TINTED BY THE LIGHT
It’s a bright, sunny day, but you don’t have your sunglasses on hand.
Not to worry. Thanks to technology, your prescription lenses can help
protect your eyes from changing light conditions and ultra-violet rays.
Photochromic lenses are optical lenses that darken on exposure to
specific types of light of sufficient intensity, most commonly ultraviolet
light. Since they react to UV light, the lenses fade back to
their clear state indoors.
