Do Your Sunglasses Have Enough UV Protection?
Updated: Feb 10, 2022
Are your sunglasses capable of filtering out harmful UV rays? Most sunglasses have some degree of UV protection, but is it enough? Keep in mind that not all polarized sunglasses offer proper UV protection.
As a trusted eye exam company, Scope Optometry shares some tips on choosing a pair of sunglasses that provides the level of protection you need.
Why UV Protection Is Important
Being exposed to UV radiation from the sun can harm your eyes and your vision. You could develop cataracts, which is a condition that occurs when the naturally clear lens inside the eye becomes cloudy or opaque. In fact, studies have shown the more time people spend in the sun, the greater their risk of developing cataracts as they age.
By wearing sunglasses that block 100% of UV radiation, you get the best possible protection from these health risks. Just make sure to wear your sunglasses whenever you’re outdoors during daylight hours, even when it’s cloudy. Cloud cover doesn’t prevent damaging UV rays from reaching your eyes.
How to Check If Your Sunglasses Have UV Protection
Here are a few other things to keep in mind:
If you’re spending a lot of time outdoors (especially around water), consider investing in wrap-around sunglasses. These protect your eyes from UV rays that come in from the side while also keeping them from being dry. Some pairs are quite affordable.
Polarization is actually different from UV light absorption, but many polarized lenses do feature a UV-blocking coating. When you check the label if the lenses provide maximum UV protection, also make sure to do the same for the lens color and tint, lens darkness and mirror coating.
