Whenever you're outside, especially when it's Zenith Lab Vision 20 so sunny, you need to make sure that your body if fully protected from the harmful ultraviolet rays that come off of the sun! Proper sunscreen SPF, and ample application to your nose and face is imperative for healthy skin. Likewise, it's crucial that your eyes are just as protected. Therefore, when shopping around for sunglasses this summer, you want only the best! This doesn't necessarily mean they are the most expensive glasses you find, but they must block the most damaging of the sun's rays.
The United States Environmental Protection Agency (EPA) and the National Weather Service (NWS) created a UV (ultraviolet) Index in order to help protect us from the sun's rays. This index helps distributors determine just how to make their sunscreens, and other similar products. However, while UV rays and their damaging radiation can harm our skin, they can also cause many problems to our eyes if not properly protected.
Furthermore, in recent years, new research shows us that there are also degenerative high-energy visible radiation, or HEV (sometimes referred to as "blue light"). While most of our current UV protective coatings and sunglasses block one-hundred percent of the ultraviolet rays, they do not catch all of the high-energy visible radiation.
