This special glass called "photometric" glass. In its manufacturing process, mixed into a light-sensitive material in advance, such as catching silver of silver and Australia (collectively referred to as silver halide), there is a small amount of copper oxide catalyst.

Spectacle lenses from no color to light gray, dark brown, dark glasses and change back to ordinary glasses are silver halide becomes magic. And imaging exposure of the photosensitive film is very similar to the process of change in the glass color glasses.

See silver halide light decomposed into many black silver particles uniformly distributed in the glass, the glass lens so dim, blocking the passage of light, which is Cheap Ray Bans glasses. However, on the photographic film, the silver atoms generated in the decomposition of the silver halide and halogen atoms, still tightly side by side. Back to a little darker place, in the promotion of the copper oxide catalyst, silver and re-halogen compounds to produce silver halide glass lenses become transparent.

Silver halide resides in the glass, the decomposition and recombination reactions repeatedly infinite. Photographic film and photographic paper can only be used once, color glasses, however, has been using it.

Color glasses with the intensity of light Darker that can absorb the harmful ultraviolet rays of the human eye, is indeed the glasses in the top grade.
