- Photochromic Reading 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. They are an excellent solution for people who hate constantly switching between their reading glasses and their shades
- Photochromic lenses are also referred to as light-sensitive lenses". Glass lenses are adding silver halide, but now is the mainstream of photochromic resin lenses, adding of spiro and other chemicals in the acrylic resin lens, so that the original colorless and transparent lenses, in bright light, will become colored lenses, to do the protection, so is suitable for indoor and outdoor use.
