Photochromic glasses Lenses are clear when indoors or at night and automatically darken to a sunglasses tint when exposed to UV sunlight. Lenses will begin to clear as soon as they are away from UV sunlight, and will be noticeably lighter and mostly clear within a few minutes. They absorb UV radiation that can otherwise damage your eyes.
