II. Photochromic lens:
 | - The definition of photochromic lens
Photochromic lenses, often called or reactolights, darken to a sunglasses tint when exposed to sunlight, or U/V ultraviolet, and return to a clear state when indoors, away from U/V light. Photochromic lenses are made of many lens materials including plastic, glass or polycarbonate. They are typically used as sunglasses that conveniently switch from a clear lens indoors, to a sunglasses depth tint when outdoors, and vice versa. |
- The technology of photochromic lens
Tiny molecules of silver halide and chloride are embedded within a photochromic lens which is invisible and clear until exposed to sunlight/UV rays. A chemical process takes place when exposed to sunlight/UV and the molecules effectively move, change shape and absorb the light. This process changes the molecules and they darken to a sunglasses shade/tint.
The photochromic lens will remain in this 'darkened' sunglasses state whilst exposed to sunlight/UV and the molecules will reverse the process once the lenses are removed from the sunlight/UV rays returning to the original 'transparent/clear' lens.
- The benifits of photochromic lens
- Outstanding Color Performance
Fast speed of changing, from white to dark and vice versa.
Perfectly clear indoors and at night, adapting spontaneously to varying light conditions.
Very deep color after change, the deepest color can be up to 75~85%.
Excellent color consistency before and after change. Perfect blockage of harmful solar rays and 100% UVA & UVB. |  |
