Photochromic lens:
Photochromic lenses - lenses that are clear indoors and darken when exposed to sunlight - offer a convenient way to protect your eyes outdoors from UV rays and bright light without having to carry around a pair of sunglasses.
The molecules in photochromic technology work by reacting to UV light. However, temperature can have an effect on the reaction time of the molecules.
