Photochromic lens

Photochromic lens

Photochromic lenses are lenses that darken on exposure to specific types of light, most commonly ultraviolet radiation. Once the light source is removed, the lenses will gradually return to their clear state. Photochromic lenses may be made of glass, polycarbonate, or another plastic.
Photochromatic lenses contain millions of molecules of silver chloride or another silver halide embedded within them. These molecules are transparent to visible light in the absence of ultraviolet rays, which is normal for artificial lighting. When exposed to ultraviolet rays, as in direct sunlight, the molecules undergo a chemical process that causes them to change shape and absorb portions of the visible light, causing the lenses to darken. This process is reversible; once the lens is removed from...

Skugga sunglasses tint on command or automatically - Gizmag

In less than a year, electrochromic sunglasses have gone from being experimental to an actual product, with Dutch startup Ctrl announcing its tint-on-demand Ctrl One cycling glasses just this month. Electrochromic sunglasses are similar to traditional photochromic transition eyeglasses, in that their lenses automatically switch from clear to tinted when exposed to ultraviolet light. That said, while photochromic lenses take several seconds to make the change, electrochromic lenses do so instantly. Additionally, their users can switch between clear and tinted modes manually – this could be particularly useful in situations such as driving, in which photochromic lenses won't darken because they're shaded from the sunlight.
