How do sunglasses protect your eyes from ultraviolet rays?
This creates an annoying and
sometimes dangerous intensity of light that we experience as glare. Polarizedsunglasses cut
glare and haze so your eyes are more comfortable and you can see better.
Polarized lenses contain a special filter that blocks this type of intense
reflected light, reducing glare.Your optician can verify that the lenses you
choose provide 100 percent UVprotection. But for HEV protection, color does matter. Most sunglass lenses thatblock a significant
amount of blue light will be bronze, copper or reddish-brown (see lens tint
guide).
