WHAT DOES PHOTOCHROMIC MEAN?
Photochromic Lenses have a coating that responds to UV light. When out in the sun, they'll get darker, and the lens will lighten without UV exposure. Check your local UV index with these babies - the higher your UV index, the stronger these will respond. Only true-blue UV light triggers the reaction so wearing these in your car, or indoors, while stylish, won't have the reactive flair.
