The Cause and Fix for Uncomfortable Glasses

If your glasses ever feel uncomfortable on your face, you'll find the answer to why in this article, and learn how to solve the problem.

Whether you wear glasses all day or just for a few hours at a time, it’s critical that you feel at ease. Unfortunately, uncomfortable glasses is quite a common problem. Typically, outgrown glasses are the issue, but sometimes new glasses are uncomfortable as well.

If you’re always saying or thinking “my glasses are uncomfortable,” keep reading to learn the causes and solutions to ensure you are pain-free when wearing your prescription glasses.

Why do my glasses hurt my nose?

You may suffer from a painful nose bridge if you wear glasses for lengthy periods of time. The main point of contact between your face and your glasses is the nasal bridge.

As your nose supports and carries the weight of your spectacles, it can sometimes cause your glasses to feel uncomfortable on the nose. As well as a correct fit, looking for prescription glasses with adjustable nose pads can be a good option to reduce this discomfort.

DID YOU KNOW?

If you’ve got a low nose bridge or high cheekbones, Asian fit glasses may be a more comfortable option for you.

How to adjust nose pads on glasses

If your current glasses have nose pads that you feel cause more harm than good, you can get the nose pads adjusted to fit the shape of your nose.

Choosing the right material for nose pads can also help you feel more comfortable when wearing your glasses. Materials such as silicon and finding the correct position will be the key to how to keep glasses from slipping off your face.

Why are my glasses uncomfortable behind my ears?

Along with our noses, our ears are another common area of contact with glasses. Ache behind the ears is most often caused by frames that are excessively tight. If your glasses are too small, they will press on your skin and damage and disrupt your circulation.

This can cause sore skin, redness, and even headaches. The correct fit or a quick adjustment can easily solve this issue.

High-index lenses vs. regular lenses

Good-fitting glasses should sit snugly on the bridge of your nose without pinching or feeling too tight on your head. Even when you’re moving around, the frames shouldn’t press into your face. It’s possible that the sizing is incorrect if your glasses pinch or move about.

When buying prescription glasses or sunglasses, it is critical to get the glasses sizing correct. Use our size guide to ensure a proper fit and reduce the risk of soreness on the bridge of your nose or behind your ears.

Sometimes all that is required to alleviate discomfort is a simple adjustment. When it comes to adjusting glasses, SmartBuyGlasses understands that you might not have the time to take the frames to a professional.

Fortunately, with the appropriate guidelines, you can adjust your glasses like an expert from the comfort of your own home. For assistance, see our instructions on how to adjust plastic glasses.

The last factor to consider is the material of your frames. Heavy frames, in addition to a poor fit, might cause discomfort. As a solution, you can experiment with glasses made from lightweight materials such as carbon fibre or titanium glasses.

Now with the correct knowledge of how to avoid uncomfortable glasses, you can shop with ease online at SmartBuyGlasses and know you’ll be comfortable no matter what.

Everything You Need to Know About Gradient Sunglasses

Ask our opticians

Gradient sunglasses work well in both outdoor and indoor settings , reducing eye strain while letting in enough light for great vision clarity.

What are gradient sunglasses?

Gradient sunglasses come in dozens of frame styles and colours, but they all have one thing in common. As opposed to standard tint shades, these glasses have a gradient lens tint. This means their lenses are darker at the top, gradually fading to a lighter shade towards the bottom.

Because they feature a variation in lens tint, gradient lenses handle transitions between light and dark better, offering the best of both worlds: complete clarity of view and protection from the sun’s rays from above. For an enhanced view, you can also add prescription lenses to gradient tint sunglasses.

How do gradient sunglasses work?

In a practical sense, gradient glasses work by providing both effective protection from sunlight and a clear field of vision thanks to the varying intensity of the tint. The lens is dark at the top to protect the eyes, but clear at the bottom to allow for clear reading.

The gradient lens tint is achieved by adding a metal oxide to the lens during the production process, creating a difference in tones. Another method is dipping the lenses in dyes, with the same result. This transition from a lighter to a darker tone is what differentiates them from regular sunglasses, which have a standard lens tint.

Are there different types of gradient sunglasses?

You’ve probably seen plenty of brown gradient lenses out and about, but you can choose from a wide range of colour options for your gradient lens tint. Colours aside, there are two styles of gradient available. Most people go for the more popular single gradient with its ‘top-down fade”.

If you want something a little different, there are also double gradient lenses, which are tinted from both the top down and the bottom up so that the midsection is the lightest. Double gradient sunglasses can also incorporate two different colours into the lenses.

When can I use gradient sunglasses?

Gradient lenses are commonly used for driving, and they operate in much the same way as sun blinds on a car’s windshield. They protect the eye from overhead sunlight while simultaneously allowing a perfect view of what is both inside and outside the vehicle.

They’re also practical in cloudy and overcast conditions as they let in more light than regular sunglasses. If you are hiking, they offer protection from the sun’s rays above you while also allowing you to easily see where you are treading.

Snow or water sports enthusiasts also benefit from the unique qualities of gradient sunglasses for this reason. That said, if you are looking purely to reduce glare, you may want to look at getting a polarised or mirrored pair instead.

DID YOU KNOW?

Some double-gradient sunglasses have two top-down fades, resulting in two clear sections and two dark sections on each lens.

Are gradient lenses better than polarised lenses?

Polarised and gradient sunglasses share some common features. Both types reduce glare (to different extents) and eye strain, protect your eyes from sunlight, and provide general comfort when outside in the sun.

However, there are also some differences between them, so one type may be more adapted to your specific needs. For example, polarised lenses have a filter to reduce reflected glare that is not present in gradient sunglasses, making polarised lenses superior in this regard.

Gradient sunglasses

The light and dark combo of gradient glasses is particularly advantageous when you’re going between indoors and outdoors. However, not all gradient sunglasses provide UV protection, so they may not be the best option for spending extended periods under strong sunlight.

Because gradient tint sunglasses provide shade from overhead light while giving you a clear field of vision, they are well-suited for driving, reading outdoors, gardening, and other similar activities. Looking at LCD screens is also more comfortable with a pair of gradient sunglasses.

Polarised lenses

The lens material of polarised sunglasses is treated with a chemical to filter light coming in. This light filtration then blocks horizontal light waves created by the sun’s reflection off surfaces, which we experience as glare. Therefore, polarised sunglasses limit glare intensity to a greater extent than gradient glasses.

As such, polarised sunglasses are perfect for watersports, skiing, golf, and other outdoor activities. Most polarised sunglasses also block UV rays, which is vital if you plan on being out in the sun for long periods.

Exposure to UV rays elevates the risk of developing conditions such as cataracts later in life. UV protection should always be a top priority when choosing a pair of sunglasses.

What are the benefits of gradient sunglasses?

Gradient sunglasses bring form, function, and style together in a very versatile package. When passing from bright to darker settings, you’ll have clear, comfortable vision in both cases, without the need to take them off.

If you’re looking for sunglasses purely for style purposes, gradient sunglasses offer a compromise; a subtle fashion statement without having to obscure your eyes with dark lenses. Classic silhouettes like the Ray-Ban Aviator and Wayfarer come in a range of gradient options, while Balenciaga and Prada have some more modern, trend-based frames.

You don’t have to sacrifice proper eye contact while wearing them either, thanks to their light shade. Prescription gradient lenses are available if you need more than just aesthetic appeal from your eyewear.

If you think that two-tone sunglasses are a good fit for your lifestyle, we advise you to go for a pair with UV protection. The harmful effects of UV rays aren’t limited to your skin. When it comes to eye health, UV protection is extremely important.

Before investing in a pair of shades, take into consideration what you’ll be using them for. Depending on your habits, gradient sunglasses could be more suitable than regular sunglasses.

If you have any questions about gradient sunglasses, you can ask one of our certified online opticians. Be sure to check out our other Optical Center articles to stay well-informed on all things ocular.

Transitions® Lenses

Ask our opticians

Transitions® lenses contain photochromic molecules, which cause the lenses to automatically darken and clear depending on the surrounding light conditions.

If you’ve ever found yourself fumbling between your prescription eyeglasses and prescription sunglasses when moving from indoors to outdoors, Transitions® lenses are a great solution to make everyday life simpler.

Transitions® lenses are a type of photochromic lens that is transparent when indoors but automatically darkens outdoors when exposed to UV rays. With their unique design, they may eliminate the need for two separate pairs of glasses.

What are Transitions® lenses?

Considered light intelligent lenses, Transitions® lenses are eyeglasses that are designed to adapt to changing environments. Their lenses automatically adjust their tint according to the surrounding light conditions. These light-adaptive lenses are designed to darken when exposed to UV light and become clear again indoors or in low-light conditions.

These light-adaptive lenses are designed to darken when exposed to UV light and become clear again indoors or in low-light conditions.

How are Transitions® lenses different from ordinary lenses?

Transitions® lenses differ from ordinary lenses primarily in their ability to adapt to changing light conditions. Transition lenses are designed to be light-sensitive and react to UV exposure, while standard lenses are not.

Transitions® lenses offer built-in UV protection. When they darken, they block a significant amount of harmful UVA and UVB rays, reducing the risk of eye damage. Unless specifically treated with a UV coating, ordinary lenses may not provide the same level of UV protection.

It’s important to note that while Transitions® lenses provide convenience and UV protection, they may not be suitable for every individual or specific situation. Personal preference, lifestyle and specific optical needs should be considered when choosing between Transitions® lenses and ordinary lenses.

Personal preference, lifestyle and specific optical needs should be considered when choosing between Transitions® lenses and ordinary lenses.

What is the difference between Transitions® and photochromic lenses?

Transitions® lenses and photochromic lenses work the same way and are essentially the same thing. Transitions® is a brand name and type of photochromic lens manufactured by Transitions Optical Limited.

Therefore, the primary difference between the two lies in their names and the companies that produce them. Photochromic lenses, including Transitions® lenses, are eyeglass lenses that automatically adjust their tint in response to changing light conditions.

While Transitions® lenses are a well-known and widely used brand of photochromic lenses, other lens manufacturers also produce photochromic lenses under different names. These lenses may have slight variations in activation and fade speeds, darkness levels, or available lens options.

Still, the core technology and purpose remain the same—to provide an adaptive tint that adjusts to different lighting conditions.

How do Transitions® lenses work?

Lens technology is constantly evolving and continuously improving. Transitions® lenses work through a process called photochromism. The lenses contain unique photochromic molecules that undergo a chemical reaction when exposed to UV light, causing them to change their molecular structure and darken.

In their unexposed state, Transitions® lenses are transparent, allowing for clear vision indoors or in low-light conditions. When the lenses are exposed to bright light from the sun or other sources, the molecules in them react and change form. As a result of the chemical reaction, the molecules rearrange themselves, causing the lenses to darken.

The speed at which Transitions® lenses darken depends on the presence of UV light, its amount and the temperature. In the bright sun, they will change more quickly; in less light, they’ll change more slowly. They generally begin darkening within seconds of UV exposure and continue to darken for a few minutes.

When Transitions® lenses are no longer exposed to UV light, such as when you move indoors, or the sun goes down, the molecules gradually return to their original configuration. This causes the lenses to lighten and eventually become clear again, typically taking about 2-3 minutes.

Pros and cons of Transitions® lenses

It’s essential to consider individual preferences, lifestyle and specific optical needs when assessing the advantages and disadvantages of Transitions® lenses. While they offer numerous benefits, some individuals may still prefer dedicated prescription glasses and sunglasses for specific purposes or styles.

One of the most significant advantages is their convenience and cost-effectiveness. They eliminate the need to switch between two pairs of glasses when transitioning between indoor and outdoor environments. While the upfront cost of Transitions® lenses may be higher than regular lenses, they can potentially lead to long-term savings.

Transitions® lenses also offer built-in UV protection, which is essential in safeguarding your eyes from sun damage caused by UVA and UVB rays. By adjusting their tint based on the surrounding light, they also help reduce eye fatigue and strain, reduce glare and provide comfortable vision by optimising the amount of light entering the eyes.

There are also some potential disadvantages to consider. The speed at which Transitions® lenses darken and clear indoors may vary depending on temperature, UV intensity and lens brand.

In very hot climates, the lenses may not darken as much as desired, potentially providing less sun protection. Likewise, the lenses may not lighten as quickly in extremely cold temperatures, causing them to remain darker indoors.

Another thing to consider is the limited lens activation behind the windshield. As most car windshields are designed to block a significant amount of UV radiation, which is necessary for the lenses to activate and darken.

Some models, including the Transitions XTRActive® lenses, have more photochromic molecules allowing them to transition even while in the car. These lenses always have a very light base tint and will not go as dark in the car as outdoors.

Can you get non-prescription Transitions® lenses?

Transitions® lenses are available in prescription and non-prescription options, allowing individuals with or without vision correction to enjoy the benefits of light-adaptive eyewear.

Non-prescription Transitions® lenses are commonly used by individuals who do not require vision correction but still want the convenience of photochromic glasses. They provide the same light-adaptive properties as prescription Transitions® lenses, automatically adjusting their tint in response to changing light conditions.

Can Transitions® lenses offer blue light protection?

Transitions® lenses are designed to protect your eyes from UV rays outdoors and harmful blue light indoors. Transitions® Signature® GEN 8™ lenses are specifically designed to filter up to four times more blue light indoors than clear lenses.

If you spend a lot of time in front of digital devices, you may want to consider Transitions® XTRActive®, which filters up to seven times more blue light indoors than clear lenses.

DID YOU KNOW

Transitions® lenses offer vision correction and protect against blue light and UV rays, making it easy to transition from screens to sunlight.

How to care for Transitions® lenses

To ensure the longevity and optimal performance of your Transitions® lenses, taking proper care of them is essential. Clean them regularly to remove dirt, smudges and oils. Use a mild, non-abrasive lens cleaner or a gentle soap solution with lukewarm water. Avoid using harsh chemicals or abrasive materials that could damage the lenses.

When cleaning your glasses, use a soft, lint-free microfiber cloth specifically designed for cleaning eyeglass lenses. Store your Transitions® lenses in a protective case to prevent scratches or accidental damage when not in use.

Excessive heat or prolonged exposure to direct sunlight can potentially affect the performance and longevity of the lenses. Avoid leaving your glasses in hot temperatures, such as a closed car during sunny days. When not wearing your glasses, store them in a cool, dry place away from direct sunlight.

Most photochromic lenses perform well for 3+ years, but eventually, they will become less reactive to light conditions and take longer to shift between clear and tinted. It is important to schedule eye exams with your eye doctor to maintain eye health. They can assess the condition of your glasses, check for any signs of wear or damage and ensure your prescription is up to date.

What are High Index Lenses?

Many people are concerned about thick lenses, but high-index materials allow for thinner lenses even for high prescriptions.

SUMMARY

High-index lenses are designed for strong prescriptions. They offer a thinner, lighter alternative to traditional lenses. Usually made from lightweight plastic, they bend light more efficiently and provide a sleek fit for most frames. Although they can be more and expensive, they improve comfort and are better suited to higher prescriptions than other materials.

The lens or refractive index measures how efficiently a lens material bends light, determining the thickness of a lens: materials with a higher index bend light more effectively, allowing lenses to be thinner while providing the same level of vision correction.

This is especially beneficial for individuals with stronger prescriptions, as high-index lenses reduce the bulkiness typically associated with traditional lenses.

Read on to learn exactly what high-index lenses are and how they compare to other lenses.

What makes high-index lenses special?

In the past, those with higher prescriptions wore thick glass or plastic lenses that were quite bulky and gave a bug-eyed look due to the thickening of the lens towards the edges or centre. However, the emergence of high-index materials changed this.

Now, strong refractive errors such as high myopia, hyperopia, presbyopia, or astigmatism can be corrected with thinner lenses that don’t compromise on efficacy.

High-index lenses are thinner, lighter and more durable. Prescription glasses equipped with high-index lenses are noticeably slimmer, lighter and more aesthetically pleasing, which is why they are recommended for people with strong eyeglass prescriptions.

Thanks to high-index lenses, strong prescription glasses can now be worn in stylish, semi-rimless and even rimless styles. Most high-index lenses are also aspheric, making them slimmer and greatly eliminating the “bug-eye” look.

DID YOU KNOW?

The first high index lenses were produced in 1983 by Mitsubishi Chemical, made from polycarbonate.

What are high-index lenses made of?

Most high-index lenses are made of a particular type of lightweight plastic that bends light more efficiently than other lens materials. Notably, Mitsubishi Chemical has patented many of these advanced materials, specially designed for their superior refractive index.

While high-index lenses made of glass also exist, they are prescribed less frequently due to their heavier weight and reduced impact resistance compared to their plastic counterparts.

Advantages of high-index lenses

High-index lenses are the solution for accommodating high prescriptions in thinner lenses. That is not all, though; here are all the advantages of choosing high-index lenses:

Thinner and lighter than other lenses: The specific plastic blend makes it possible to create thinner and lighter lenses that provide better light refraction than regular ones.
Versatility: High-index lenses can be customised according to your needs and preferences. They can be single vision, progressives, transitions and can be treated with many coatings such as blue light block, polarisation, anti-reflective and more.
Comfort: Because they are lighter and thinner than other types, high-index lenses offer a higher level of comfort. With high-index lenses, your glasses will not be heavy on your ears and nose, making your life easier.
Great fit for most frames: High-index lenses fit many different frames. Always remember that the bigger the frame, the thicker the lens, so opticians recommend smaller frames if you have a strong prescription.

Disadvantages of high-index lenses

Although the pros outnumber the cons, here are a couple of things to consider when it comes to high-index lenses:

More fragile than other lenses: High-index lenses are not as impact-resistant as other types of lenses. This means that they may not be the best fit for children or those doing sports.
More expensive than other lenses: These lenses offer many benefits but are also a bit more expensive than regular lenses. For many wearers, though, their benefits outweigh the price.

Difference between high-index and other lenses

High-index vs. regular

Both regular lenses and high-index ones bend light to correct refractive errors. The difference is that regular lenses have to be thicker to correct strong prescriptions, while high-index lenses are made of a material that bends light more efficiently. This allows the lenses to be lighter and thinner.

In general, the stronger the prescription, the higher the index should be for the glasses to offer comfortable vision and fit. For example, a regular lens with a 1.50 index and a 1.67 high index lens can have the same prescription, but the high index lens would be around 30% thinner.

High-index lenses vs. polycarbonate

Polycarbonate lenses have a 1.59 index, making them thinner than standard lenses but not as thin as high-index lenses.

They are, however, more impact-resistant than high-index lenses, offering increased durability. This is why polycarbonate lenses are recommended for children’s glasses, sports eyewear and safety goggles, even though they don’t provide the same visual clarity as other plastic lenses.

1.67 vs. 1.74 high-index lenses

Both 1.67 and 1.74 high-index lenses can accommodate strong prescriptions. The difference is in the thickness. 1.74 high-index lenses are up to 10% thinner than 1.67 high-index lenses.

For reference, 1.67 high-index lenses are recommended for prescriptions with an SPH correction between +/-7.00 and +/-9.00 and a CYL correction between +/-3.25 and +/-4.00.

1.74 high index lenses are instead known for being “as thin as possible” and recommended for even stronger prescriptions, namely those with an SPH correction of +/-9.25 and above and a CYL correction between +/-4.25 and +/-6.00.

Are high-index lenses right for me?

Whether high-index lenses are right for you depends on your prescription, lifestyle and personal preference. These lenses are ideal for those with strong prescriptions who want thinner, lighter and more aesthetically pleasing eyewear. Their versatility and ability to fit a variety of frame styles make them a top choice for many.

However, it’s essential to weigh the pros and cons. While high-index lenses offer comfort and style, they may be less impact-resistant and more expensive than standard options. If you lead an active lifestyle or need durable lenses for sports or heavy-duty use, other materials like polycarbonate might be more suitable.

Consider your unique needs and consult with your optician to determine whether high-index lenses align with your vision requirements and daily activities. And if you need any additional clarifications, feel free to reach out to our opticians–they’re here to help.

Glasses for Small Faces: Tips on Getting the Perfect Eyewear Fit

Ask our opticians

Ask now

Face shape is often cited as a consideration when buying glasses, but face size is also important. Here's our guide to glasses for small faces.

Wondering if you need glasses for small faces? Have you ever been shopping for glasses and found that no matter how many pairs you try on, you still look like you have massive bug eyes?

Glasses that drown your features, overpower your face, and slide off your nose? If you can relate, you most likely have a small face shape and would benefit from buying glasses for small faces.

There are plenty of brands that now manufacture petite glasses specifically for narrow face shapes. This means that you can find the perfect pair, pull off the most stylish of looks and be trendy with your eyewear, no matter your face shape and size.

How should glasses for small faces fit?

Comfort is the number one factor here. The aim of glasses for small faces is to provide a better, more secure fit without compromising comfort. So when you try on a pair of glasses for small faces, ensure they are the right size and feel secure without squeezing your head.

Glasses for small faces are designed to have a shorter lens width, shorter temple arms, and a narrower bridge frame. You can learn more about glasses frames here.

Many people with a narrower face shape resort to wearing children’s sunglasses. However, this often involves temples that are too short. Glasses for small faces are, therefore, the perfect solution, offering frame arms that are slightly longer than those on kids’ eyewear.

DID YOU KNOW?

People with small faces sometimes resort to wearing children’s glasses for a better appeaance on their face, but the temples are usually too short.

How to find out if you need glasses for small faces?

There are several ways to find out if you need a smaller size of glasses.

Option 1: Find out what size your current glasses are. Look at the inside of the glasses frames, and note the numbers that appear. Read on to find out what the measurements mean.

Add a few millimeters to the measurements if you feel they are too tight, or reduce the number if they are too large when you wear them. For more information on finding glasses measurements, read our article here.

Option 2: Take a ruler or flexible measuring tape. To find your face width, stretch the measuring tool from temple to temple. Next, repeat the action across your jawline. This starts roughly an inch below your ear. Pick the larger of the two measurements: this is your face width.

Now you need to find your face length. Go from your chin to the middle of your hairline. And here comes the maths: divide your face height by your face width. If you have a narrow face, your face height will be over 1.5 times the width.

Option 3: The process is considerably more straightforward if you already know your eye and bridge size. Simply follow this equation:

Eye size + bridge size = frame size

Eg. 47mm + 21mm = 68mm

Average frame sizes

In general, spectacles will look their best when the total width of the face matches that of the glasses frames. When considering glasses for small faces in particular, it is actually not a problem if the frame size is equal to, if not wider than, the face width.

This means you should not worry if your glasses frames extend beyond your temples by about 3mm on each side. This widens the appearance of the face, creating a sense of balance with the length of the face.

For average face sizes, the frame width is generally 138mm wide. In contrast, a narrower face will require a frame width of nearer 126mm, which is quite a significant difference. If you find your face measurements within these figure ranges, you might want to consider wearing glasses for narrow faces.

Here are some typical measurements for glasses for small faces.

Total frame width: 123-127mm (114-122mm for properly petite faces)

Lens width: 47-50mm (45-46mm for tiny faces)

Bridge width: 16-20mm (15-16mm for the narrowest of faces)

The lens width quoted here will offer a narrow fit in most frame shapes. However, round frames are an exception. Round frames tend to have slightly wider bridges and more petite lenses. On average, 43-48mm represents a typical lens width in round glasses for small faces.

Due to the smaller lens size, the bridge size will be 2 or 3mm wider than that of other frame shapes.

Tips for checking that your glasses for small faces fit you well

Simply put, small glasses that fit properly will have frames that closely match the width of your face. In addition, the bridge will sit comfortably on your nose. A plastic fix bridge should sit flush at each side of the nose; there should be no gap at the top of the bridge on the frame and the bridge of the nose.

Metal frames with nose pads can be adjusted by moving the pads out or in to loosen or tighten the fit at the bridge. In addition, your eyes will be perfectly centered in the middle of the lens.

Those are the basics. Next, you want to double-check that the glasses fit securely on your face. If you can fit a finger down between the side of the frame and your temple, then it’s too big and won’t be able to be adjusted. The issue will only worsen and get especially bad in warm weather.

If the frames pass this test, they can move on to the next round! In this next step, you want to be 100% sure that the glasses fit comfortably on your head and don’t feel too tight. If when putting the glasses on, the sides stretch out, it will be too tight and will leave red marks down the side of the face.

This would stop you from wearing the spectacles for long periods. When trying on the frames, one way to check this is to see if there are any red marks or a hint of indentation behind your ears when you remove them. If you do find such a mark, choose a different pair.

Yet another checkpoint before buying petite glasses is how flush they are to your face. Consider whether your eyelashes are touching the lenses. This can be adjusted in most metal frames but not so easily in plastic frames. 9 out of 10 frames will have a slight tilt in them to accommodate this.

You need to ensure that your eyes can move freely without your lashes coming into contact with the glasses. At this point, it is important to remember that your prescription lenses will be thicker than the test pair.

One final pointer to consider before settling on a pair of eyeglasses for small faces is where they sit on your face. Make sure the frames rest on the bridge of your nose rather than your cheekbones. The glasses don’t fit you correctly if the frames move as you switch between facial expressions.

Tips for choosing glasses for small faces

Once you’ve found a few pairs that meet the measurement criteria and pass all the good-fit and style tests, you can consider the frame design that will be most flattering for your narrow face.

People with smaller faces often find that more delicate frames, such as metal frames or thin acetate ones, are more flattering. Such petite frames complement their petite features and narrow face shapes.

Another thing with glasses for narrow faces is that narrow frames draw more attention to your eyes. Therefore, it is recommended to find an acetate frame, the color of which matches your eyes. It will make your eyes stand out and make the glasses look perfectly natural on your face.

Best glasses shape for small faces

Here are some quick tips for finding the frames that complement your face shape. Find your face shape with the helpful guide here.

Oval face shape:

Narrow frames will make your face appear overly long
Find frames with more height, such as round or square glasses
Thicker frames with wider lenses or aesthetic embellishments will help widen your face

Short face shape:

Tall frames will cause your face to look swamped in the glasses
Go for shorter frame shapes like rectangular or oval
Avoid oversized or pilot frames. These would accentuate the short face shape
Be cautious with extra thick frames or black frames, as these could make your face look even smaller

Pear-shaped face:

Go for frames that are heavier on the top, such as browline glasses

Round face shape:

For round faces, we recommend more angular glasses frames with plenty of character, such as cat eye frames
Square frames with bold colors will project a look of total confidence

Square face shape:

As the exact opposite of round face shapes, balance a square face with round or oval frames for a softer look

Diamond or Heart-Shaped face:

Take the focus off the pointed chin with a pair of browline glasses or classic cat eye frames

The two most important things to consider when choosing a pair of glasses for small faces are your face shape and the lens index. The lens index depends on your prescription details; the higher the prescription, the higher the index. Ask your eye doctor or one of our opticians for advice on the best lens index for your prescription.

Glasses that fit you properly are essential to ensure your prescription lenses do their job. Your eyes must be centered in the lenses to guarantee clarity of vision.

As a general rule, positive prescriptions result in larger-looking eyes. Therefore, those with higher prescriptions should be careful of looking “bug-eyed” due to thicker lenses. On the other hand, high negative prescriptions can cause the lenses to peek out at the side of the frames.

To help remedy this combination, avoid rimless glasses for small faces. A solution for higher prescriptions could be choosing thinner lenses that will reduce the magnification of the eye. For high negative prescriptions, plastic frames will help hide the thickness.

What glasses look good on a small face?

In this article, we have gathered all the tips to find the perfect eyewear fit. The most important things to know when shopping for glasses for a smaller face are your face shape and size. With this information and by following our tips and guidelines, it will be easy to find the perfect glasses.

Remember that the same tips also apply to sunglasses, blue light glasses, and any other type of glasses. If you have any further doubts or questions, you can always reach out to our team of certified online opticians for support.

Check that your stylish glasses for small faces fit you well

To put it simply, glasses for small faces that fit properly will have frames that closely match the width of your face. In addition, the bridge will sit comfortably on your nose, and your eyes will be perfectly centred in the middle of the lens.

Those are the basics. Next you want to double check that the glasses fit securely on your face. Test this by shaking your head to and fro, and tilting it up and down. If the glasses slide down even a fraction, these are sadly not the glasses for you. The issue will only worsen over time, and get especially bad in warm weather.

If the frames pass this test, they can move on to the next round! In this next step, you want to be 100% sure that the glasses fit comfortably on your head, and don’t feel too tight. If the frames put any pressure on the point behind your ears, you will inevitably suffer from headaches.

This would stop you wearing the spectacles for long periods of time. One way to check this when trying the frames on, is to see if there are any red marks or a hint of indentation behind your ears when you remove them. If you do find such a mark, choose a different pair.

Yet another checkpoint before buying glasses for small faces, is how flush they are to your face. Consider whether your eyelashes are touching the lenses. You need to ensure that your eyes can move freely, without your lashes coming into contact with the glasses.

At this point, it is important to bear in mind that your prescription lenses will be thicker than the test pair.

One final pointer to take into account before settling on a pair of glasses for small faces, is where they sit on your face. Make sure that the frames rest on the bridge of your nose, rather than on your cheek bones. If the frames move as you switch between facial expressions, the glasses don’t fit you correctly.

Eye Twitching- Meaning, Causes, Prevention & Treatment

Why Is My Eye Twitching?

Eye twitching is usually just a harmless muscular spasm, but there are other potential causes. Read up on them in this article.

Eye twitching occurs involuntarily when your eyelid blinks irregularly. This unusual blinking may occur several times per day.

As two facial muscles cause your eyelid to close and open, eye twitching may occur if there are problems with these muscles. Eye twitching can also be caused by other muscles in the eyes. Even if you have the correct prescription glasses, other factors can play a part.

Many people experience eye twitching from time to time, especially when they are tired or have had a lot of caffeine. It’s incredibly common and affects almost everyone. The majority of eye spasms or twitches are totally harmless and do not cause any significant issues. For most people, eye twitching on a continuous basis is infrequent.

Why does my eye twitch?

Your eye twitches from involuntary spasms in your eyelid muscles. In other words, it feels like your eyes are fluttering. You may not notice anything or may feel a small tug on your eyelid.

Although it might seem like everyone can see your eye twitching, it is usually quite subtle and difficult to notice, especially behind a pair of glasses or sunglasses.

A common cause of eye twitching is called ocular myokymia, also known as myokymia. Myokymia causes eye twitching that only affects the eyelid. This form of twitch or spasm is fairly prevalent and affects almost all people at some stage of their life. While it affects either the upper or lower eyelid, only one eye is normally affected at a time.

The eye fluttering might be unobtrusive or become more noticeable and annoying. Although twitching normally stops after a few minutes, it can happen again after a few hours, days, or weeks.

Eye twitching from myokymia could be caused by any of the following:

Consuming too much caffeine
Tobacco use
Alcohol use
Blepharitis (inflammation)
Eye strain or irritation
Conjunctivitis (Pink eye)
Allergies
A reaction to certain medications
Stress

There are other possible causes for eye spasms that are much less common. One is benign essential blepharospasm, which begins when both eyes blink excessively and eventually causes the eyelids to clench shut. Although this sort of eye twitching is uncommon, it can be very severe and cause difficulties.

While researchers believe it could occur from issues with certain areas of the brain, there is uncertainty about the exact cause. However, we do know that it can create problems with the muscles that surround your eyes.

Hemifacial spasm is a nervous system condition that causes the muscles on one side of the face to twitch uncontrollably, including your eyelid. The most common cause is when a blood artery contacts or pulses against a facial nerve.

Very rarely, other conditions that impact the brain or nervous system can cause eye twitching:

Parkinsons disease
Brain damage
Meige syndrome
Multiple sclerosis
Bells palsy

These conditions usually have other serious, identifiable symptoms that accompany the eye fluttering.

DID YOU KNOW?

Although it’s defintely perceptible by you when your eye twitches, it’s often compltely unnoticeable to others.

How to stop eye twitching

You know how annoying an eyelid twitch can be if you’ve ever had one. The severity of an eye twitch determines how it is treated. If your twitch is minor, there are certain things you can try at home before seeking medical care.

First, you can keep a journal and write down when your eye spasms happen. You should also make a note of your intake of some known triggers such as caffeine or tobacco. In addition, record your stress level and amount of sleep. When you start to notice a correlation, adjust your habits and see if the problem resolves itself.

If you are less patient and want to try to remedy the situation as fast as possible, you can try to reduce your eye twitching by doing the following:

Get the proper amount of sleep. A twitchy eye could be resolved with something as simple as a nap. Having a regular sleep pattern will also help you feel more well-rested.

Reduce your stress level. Eliminating stress from your life can relieve eye twitching.

Eliminate caffeine. It is common for adults to consume caffeine. We find it in coffee, but also in tea and certain soft drinks. Try to reduce your intake as much as possible.

Apply a warm compress. Addressing the affected area with a warm compress can help to relax the muscles and stop the eye fluttering.

Take a break from screens. Reduce your eye strain by minimising your screen time. Alternatively, use blue light glasses to protect your eyes during screen use.

Use eye drops. Those who suffer from irritated or dry eyes may find that it contributes to eye twitching. You can address this with eye drops.

Eye spasms that are more severe or recurrent, such as blepharospasm and hemifacial spasm, likely require medical attention.

When to worry about eye twitching

If you have a twitchy eye, it’s usually nothing to be concerned about. If the spasms are persistent, you may have a more serious condition that warrants treatment. If you have any of the following symptoms, you should see an optometrist or ophthalmologist:

The eye twitching has persisted for more than 3 weeks
Your eyelid completely clamps down with each twitch or you find it difficult to open the eye
Other parts of your face or body are twitching as well
Your eye is red, swollen, or has a discharge
Your eyelids are drooping
You feel that there is “shaking” in your vision
You feel like there’s something in your eye and also feel light-sensitive

Now that you know all you need to know about eye twitching, you can take the measures to get some relief. While eye twitching has many causes, they are rarely a cause for concern and usually goes away without the help of a medical professional.

However, be cautious of a persistent eye twitch and consult a professional if symptoms remain or worsen.

Why High Curvature And 3D Edging Lenses Are Important

Ask our opticians

Ask now

Learn about how advancements in technology have solved long-standing problems in the lens shaping process.

Blended lenses

For some glasses wearers, such as those with presbyopia, there may be a need for two or more lens powers to be applied onto the same lens. For this reason, bifocal and trifocal lenses were invented.

Bifocal lenses have two lens powers applied (one for distance and one for near vision).

Trifocal lenses have the lens powers for near and distance vision, with the addition of a lens power for intermediate vision.

Most bifocal and trifocal lens have visible lines where the lens powers change from near to distance or intermediate and this can be bothersome to some wearers.

The advancement of blending technology means that the lens segments can now be blended so the division of the segments is less visible, flowing smoothly between distances rather than having rigid division.

The only drawback with blended lenses (not to be confused with progressive lenses) is that some wearers experience reduced optical clarity, specifically at the points when the lens segments transition.

High curvature lenses

The differences in the thickness of the lenses is the result from the differences in the curvature.

A higher power lens results from a high curvature. A lower power lens results from a low curvature.

When a prescription is applied to a lens, the lens front remains unaffected. All of the lens power is applied to the back of the lens i.e. the surface which faces your eyes directly.

The prescription of wraparound lenses that we often see being used for sports and safety glasses usually has a base curve of 8 or so. It is worth noting that there are limits to the lens power with such a high base curve.

Where the sum of the lens power of one or both of your eyes falls outside the range of -4.00 to +3.00, there is a chance that wraparound lenses will not correct your eye condition effectively.

Beveling lenses has never been an easy task but the evolution of high base curve eyewear presents even bigger challenges.

The primary reason for this stems from having to cut (or bevel) the lenses in such a way that it comfortably sits in the groove of a frame.

This is not always an easy task with minus (i.e. thinner) lenses and there are even more complications with high curvature lenses.

DID YOU KNOW?

Anti-reflective coatings are a great help for glasses wearers, but a hindrance for lens manufacturers. The slippery texture makes the task of beveling more difficult.

3D edging

The introduction of 3D edging technology has resolved many problems caused by traditional lens technologies, the most common being the lens slipping during the edging process.

One of the main benefits of 3D edging technology is that it comes with an advanced tracer, which measures the base curve of the eyewire, also known as the lens frame.

With a 3D tracer, this can be measured with extremely accurate precision and the system can also measure the curve of the lens to the exact dioptric value.

Other benefits include cutting-edge features which allow the shape of the lens to be modified with greater precision, with the result of an improved lens fit.

The development of anti-reflective coatings has been a blessing for glasses wearers, however for lens manufacturers, this poses a problem in that they make the lenses too slippery to handle during the beveling process.

The ‘advanced torque feedback’ feature of 3D edging systems means that the roughing and finishing cycles of the grinding process are monitored and adjusted more frequently than traditional lens technologies.

How Do You Know What Strength Reading Glasses To Get?

Struggling to see clearly up close? Discover how to find the perfect reading glasses strength for you.

Have you noticed yourself squinting at your phone or struggling to read a menu at your favourite restaurant?

While it’s common to need reading glasses as we get older, younger people can also benefit from them due to prolonged screen time or other factors.

Understanding how to choose the right strength reading glasses can make everyday tasks much easier and more enjoyable, regardless of your age.

Do I need reading glasses?

If you’re starting to notice that reading books and holding your phone at arm’s length is becoming a daily practice, you might be experiencing the first signs that you need to wear reading glasses.

As their name suggests, reading glasses are designed to help with near vision, allowing you to see objects up close and perform tasks that require a focused eye.

As we age, our eyes undergo natural age-related changes. One common condition is presbyopia, which typically affects people in their early to mid-40s.

Presbyopia is the gradual loss of your eyes’ ability to focus on nearby objects. It happens because the lenses in your eyes become less flexible over time, making it harder to adjust your focus for different distances.

If these symptoms sound familiar, it might be time to consider getting reading glasses. They can help alleviate the strain on your eyes and make close-up tasks much more comfortable.

How to understand reading glasses strength

Reading glasses come in various strengths, measured in diopters, typically ranging from +1.00 to +3.50.

The lens strength you need depends on how much assistance your eyes require to focus on close objects. The higher the numbers, the stronger the lenses.

Reading glasses always have a “+” symbol before their strength number. We offer a large range of strengths, from +0.25 to +4.00, to suit everyone’s vision needs.

Why the right reading glasses strength is so important

Wearing the correct strength reading glasses is crucial for comfortable and effective vision correction.

Using glasses that are too weak or too strong for you can cause blurry vision, eye strain, frequent headaches and even worsen your vision over time.

It’s like wearing shoes that don’t fit – they might work for a short while, but eventually, they cause discomfort and problems.

How to find the right reading glasses for you

Finding the right reading glasses involves understanding your vision needs and testing different strengths.

Consulting an optometrist can eliminate guesswork and ensure you get the most suitable glasses.

However, before you book your appointment, here are 3 ways to determine if you need reading glasses:

At-home reading glasses test

While an at-home test isn’t the most accurate way to determine the correct reading glasses strength, it can still provide a helpful starting point.

Here’s a simple method you can use with an online reading chart:

Step 1: Print out a reading chart or use the one below
Step 2: Position yourself in front of your computer, about an arm’s length from the screen. Ensure your screen brightness is set to a comfortable level to avoid additional eye strain.
Step 3: Start from the top and try to read the smallest print you can without straining your eyes. Perform this step one eye at a time. First, cover one eye and see which line is most readable. Then, do the same with your second eye.
Step 4: Once you hit a row that you can read easily, take a note of the corresponding glasses strength number. It is possible that your eyes may have mismatched numbers.
Step 5: If possible, repeat the test with different charts to confirm your result.

Remember, this method offers a general idea of your reading glasses strength, but for the most precise results, we recommend visiting an optometrist for a comprehensive eye exam.

Choose reading glasses strength 'by age'

As you get older, the lens in your eyes changes, and you might need stronger reading glasses.

Here are general guidelines for reading glasses strength by age (this may differ if you already wear prescription glasses):

Ages 40–49: +0.75 to +1.50 diopters
Ages 50–59: +1.50 to +2.25 diopters
Ages 60 and up: +2.25 to +2.75 diopters

It is recommended that your first pair of reading glasses have a lower diopter. As you age and notice text becoming harder to read, you’ll need to increase the strength of your glasses.

Regular eye exams can help you keep your glasses up to date.

DID YOU KNOW?

The average person spends about 7 hours a day on digital devices, which can increase the need for reading glasses.

Choose reading glasses strength in person

Buying reading glasses in stores or over the counter allows you to try different strengths and find the best fit.

If there are any, use in-store reading charts or bring your own reading material to test the glasses.

Don’t hesitate to ask staff for assistance to ensure comfort and proper fit.

Different types of reading glasses

The most common type of lenses for reading glasses are single-vision lenses. In this case, both lenses have the same power.

Multifocal/progressive lenses, on the other hand, have multiple prescriptions in one lens, which makes it easier to switch between seeing close up, in between and far away.

Progressive lenses are the best choice for those looking to correct more than one problem, while single-vision lenses can be a good option if you need the same power for both eyes and only have one prescription.

And if you spend a lot of time in front of screens, adding a blue light block to your lenses can make a big difference by reducing eye strain, fatigue and headaches.

Do reading glasses help with astigmatism?

Although the symptoms of astigmatism and presbyopia may seem similar, reading glasses cannot help all individuals with astigmatism. It is important to remember that generic reading glasses only magnify whatever you look up close.

People with astigmatism may also be nearsighted or farsighted, so reading glasses are not advised if you suffer from astigmatism. To determine whether you have astigmatism, we advise seeing an eye professional.

My glasses don't work, what do I do?

If you’re already wearing reading glasses and have difficulty reading, you probably need to update to a new pair, especially if you got your readers a long time ago.

Just like us, our eyes age as well, which is the most common reason for an increased diopter.

The best solution is to head to your local optometrist and get an eye test to get the perfect pair of reading glasses for you.

If you’re struggling to find the correct reading glasses for your vision needs, it’s always best to visit your eye doctor.

Finding the right reading glasses for your needs

Finding the perfect reading glasses doesn’t have to be a daunting task.

By understanding your specific vision problems and considering options like at-home tests or in-store trials, you can discover the right strength to enhance your clarity and comfort.

Remember, the goal is to make your daily activities more enjoyable and strain-free.

Costa sunglasses are tailored to water-based activities. Their lenses contain technologies designed to optimize the experience.

Costa Del Mar, Spanish for “Coast of the Sea”, is an American brand which was founded in 1983 by Ray Ferguson. As the name implies, Costa sunglasses, Costa prescription sunglasses and the Costa Lens Technology are specifically designed for the increased enjoyment of water-based activities, sports and adventures such as fishing or boating.

Costa is world-renowned for its superior lens technologies which provide comfort and UV protection, allowing wearers to get the most out of their day on the water without being disturbed by reflective glare.

Mirror lenses

Costa mirror lenses are among the most scratch-resistant on the market as they are made with multilayered thin-film coating through a high-tech beam ion deposition process.

Costa mirror lenses are available in different colours including Blue, Green, Sunrise Silver, Copper Silver and Gray Silver.

Costa lens colours

The Costa collection offers a range of 7 lens colours and each one is best suited to different light conditions from low-light to extremely bright light conditions.

DID YOU KNOW?

With Costa C-Wall technology, liquid droplets are repelled much more effectively than on standard lenses, making C-Wall lenses very well suited to watersports.

Blue Mirror

Blue Mirror is most suitable for extremely bright light conditions when the glare is blinding such as in open water and offshore. Blue mirror lenses have a Gray Base and just 10% light transmission which helps to reduce glare from the water when you are boating or fishing in deep water, especially when the sun is very bright.

Green Mirror

When fishing inshore or on flats waters, Costa Green Mirror lenses are an ideal choice as they improve vision and contrast with their Copper Base and 10% light transmission.

Gray Silver Mirror

Those who need lenses for everyday activities on both water and land, the Gray Silver Mirror lenses with Gray Base and 10% light transmission are ideal. The Cost Gray silver mirror can reduce water glare and provide complete comfort.

Copper Silver Mirror

This lens colour is well-suited for sight fishing, everyday activities, cloudy days and all other environments or situations with varying light. Costa Copper Silver Mirror has neutral contrast, copper base and 12% light transmission.

Gray

The colour is a perfect choice for everyday activities on both water and land with 12% light transmission.

Copper

Copper is made for sight fishing, driving and everyday activities. Copper lenses increase the warm tone and contrast to make things pop. It helps to reduce glare, to increase comfort and to reduce strain on the eye.

Sunrise Silver Mirror

This lens colour is a perfect choice for low-light conditions such as sunrise and sunset. Costa Sunrise Silver Mirror heightens contrast and increases performance with 25% light transmission. However, these lenses are not suitable for driving.

Costa polarised 580® lenses

For any activities on the water and outdoors, eliminating reflective glare is key to reduce eye strain and ensure eye comfort. As a result, Costa sunglasses are 100% polarised.

By applying the signature Costa lens technology, Costa polarised sunglasses goes beyond polarisation with its collection of 580® Lenses which:

Block harmful blue light (HEV): 580® Lenses used in Costa polarised sunglasses allow greater clarity while protecting the eyes from UV light and HEV light. These lights are known to cause eye problems such as macular degeneration, pterygium, cataracts, etc.
Kill yellow light: Costa 580® Lenses help wearers to enjoy more vivid colours, sharper contrast and higher definition as they filter out all harsh yellow light.
Increase reds, greens and blues: For enhanced colour and sharper contrast, reds, greens and blues are increased by blocking yellow light. It makes Costa 580® Lenses the perfect option for conditions where wearers need more vision accuracy.

Costa offers two types of 580® lenses:

580G lenses: Costa 580G sunglasses provide unsurpassed clarity as they are made with a glass layer and encapsulated with a mirrored-layer.
580P lenses: these are made of Polycarbonate and Trivex which make the Costa Sunglasses 580P durable and lightweight.

Both of the lenses are scratch-resistant thanks to the Costa lens technology (C-Wall coating technology.)

C-Wall coating technology

With C-Wall coating technology, durable components are fused into the Costa lenses during their production and create a molecular bond.

Therefore, instead of applying a separate layer, the durable components are chemically bound into the lenses creating one single layer. This process means that the surface of the lens is completely covered so that contaminants cannot make their way through any part of the lens.

Contact angle

Costa lenses offer a contact angle of 116 degrees, far greater than the industry standard of 105-112 degrees. This high contact angle makes any water droplets that fall on the surface of the lens much rounder, making it easier for them to roll off the lens instead of flattening and spreading out which could obscure your vision.

As a result, Costa lenses are excellent at repelling water, sweat and other liquids as they can be easily wiped off from the surface of the lens. Furthermore, C-Wall also creates a smudge-free barrier for easier cleaning, preventing oil, dirt and other chemicals from sticking to the surface of the lens.

Bayer Abrasion test

Thanks to its C-Wall coating, Costa lenses have a superior scratch-resistance with a 7+ rating in the Bayer Abrasion test, greater than the industry average of 3-5. This ensures that all Costa lenses offer incredible durability.

Shop for Costa Del Mar sunglasses today at SmartBuyGlasses where there are several options to choose from in both our Costa women’s sunglasses and men’s Costa sunglasses collections. As well as having the option to buy the latest collections, you can also find end of season styles at discounted prices in our Costa sunglasses sale selection.

What Are Eye Floaters?

What Are Eye Floaters?

Ask our opticians

Ask now

Eye floaters can cast a shadow over your vision but are usually nothing more than a temporary nuisance. Read on to find out about the causes, symptoms, and treatment of eye floaters.

Eye floaters are spots in your vision that drift during eye movement. These eye flashes can become more intense when you look at something bright, such as the blue sky, sun, or artificial light flashes.

Some eye flashes might appear as black spots in vision, dots, or cobwebs that seem to dart away from you when attempting to look directly at them. In very rare cases, they are cause for concern, but it is important to contact your eye doctor immediately if you experience such symptoms.

What causes eye floaters?

One known cause of eye flashes and floaters is age. As the protein fibers that make up the vitreous, a gel-like substance of the eye, begin to shrink down to shreds, they can cause shadows. This is the most common issue causing black spots in vision and does not typically pose any serious threats to your eye health.

Sometimes, if the vitreous pulls away from the back of the eye, it is called posterior vitreous detachment. Floaters more often happen as a symptom along with a posterior vitreous detachment, but you can also get them without one.

Other, less common causes include:

Typically, colored contacts, also known as decorative contact lenses, are available in both prescription and plano forms:

Eye injuries: Inflammation in the back of the eye due to retinal detachment is one example of an eye injury that can cause floaters in vision.
Bleeding in the eye: Conditions such as diabetes can cause bleeding in the vitreous humor and can cause you to see black spots.
Nearsightedness: People with myopia are more likely to experience floaters.

Symptoms of eye floaters

Eye floaters can be a common occurrence for many people, but how do you know if you have them? If you notice tiny specks or cobweb-like shapes drifting across your line of vision, it’s possible you have eye floaters. These small, shadowy spots are caused by small clusters of cells or proteins that form in the vitreous.

While eye floaters typically do not require medical attention, it’s important to stay vigilant of any sudden increase or significant changes in the number and shape of eye floaters. It could indicate a larger issue, such as a detached retina, that could be a medical emergency.

Am I at risk for floaters?

As we age, it’s not uncommon to experience vision problems such as eye floaters. While they don’t typically pose any serious harm, they can indicate underlying health issues such as high blood pressure. Additionally, individuals who suffer from migraines or have undergone eye surgeries may also be more prone to floaters.

If you’re concerned about your general or peripheral vision, it’s always best to consult with your eye specialist to see if you require treatment. They can offer advice on how to manage your symptoms and ensure that any potential health issues are addressed.

When should you see a doctor?

Other signs that suggest you should speak with a doctor include an increased number of black dots, flashes of light or squiggly lines in vision, particularly in the same eye as pre-existing floaters. Darkened vision on the sides of the eye could also be a telltale sign. These symptoms could be linked to more serious issues, such as a retinal tear.

A retinal tear is a serious condition that should be treated immediately. If untreated, it could lead to permanent vision loss. If you have experienced any of these symptoms related to your eye floaters, you should speak to your doctor immediately to ensure you get any necessary treatments to maintain good eye health.

How will my eye doctor check for floaters?

During a dilated eye exam, your eye doctor will carefully inspect your eyes for any abnormalities, including floaters. To check for floaters, your eye doctor will use a special instrument to look at the inside of your eye.

They may also shine a bright light into your eye to better see any changes or irregularities. By carefully examining your eyes, your eye doctor can identify any issues, such as retinal tears early and help keep your vision clear and healthy.

DID YOU KNOW?

The process of checking for eye floaters is simple, painless, and nothing to be worried about. It is vital to visit an eye doctor if you are concerned about your vision to identify problems as early as possible.

Can a pair of glasses treat eye floaters?

Since you usually notice floaters and flashes under bright lights, wearing dark-lensed glasses can help minimise the effect they have on your eyesight. Glasses with a tint that reduces glare are the best option for those who experience eye floaters. At SmartBuyGlasses, there is a huge range of polarised sunglasses that are perfect for reducing eye flashes while outdoors. You can also reduce glare with a pair of photochromic lenses.

Other ways to treat eye floaters

When you have eye floaters diagnosed by a professional, they do not usually require any intervention. Eye floater treatments depend on the severity of the symptoms. If you have experienced a retinal tear or detachment, then treatment may include a laser or freezing treatment. What may occur is that this symptom of spotty vision or burst blood vessels will indicate a greater problem that could involve a surgical procedure. For cases of age-related vision spots, no treatment is recommended, just diligent monitoring of new floaters that appear. In this case, eye floaters shouldn’t threaten your overall vision. If your vision bothers you, try shifting your eyes up and down to shift the fluid around. This exercise can help eliminate the problem.
