Travel across the cosmos knowing you're better than everyone else with these Photochromic Pit Viper 2000s. Completely unexplainable alien technology allows the lens to darken when exposed to UV light, and stay clear in low light conditions, so you're prepared for anything.

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.
