For those with a more specific use in mind for their eyewear, it is worth checking the options of tinted sunglasses. Besides the fact that there are multiple types of eyeglass tinting to opt for, they all have unique benefits that they bring with various suggested uses.
As their name suggests, the tint in gradient sunglasses recedes from top to bottom, so the top of the lenses are darkest, gradually receding until there is no tint at the bottom. Gradient lenses, therefore, offer the best of both worlds: complete clarity of vision and protection from the harmful UV rays from above.
Photochromic lenses are a certain type of lens that react to different levels of UV light. You may also be familiar with this technology under another name: Transitions.
High exposure to ultraviolet (UV) rays emitted by the sun can be harmful to your skin and eyes. Plus, quite often these UV rays can reflect off surfaces such as water and buildings on cloudy days.
