What is Photochromic Lenses?
Photochromic lens is basically an optical device with photochromic substrates. That is, they tint (turn black) on exposure to UV radiations
and retain their original state (clear) in the absence of UV radiations.
That is, your photochromic glass will turn from clear to tinted, and vice versa.
Let me take you through a quick review of this process:
The anti-scratch coating is a protective coating applied to the front and back lens surfaces to protect against scratching. Our anti-scratch coatings are all premium and increase a lens' resistance to scratching, but there is no such thing as a scratch-proof lens. The best way to prevent scratching is to make sure that nothing hard (i.e. keys, pavement, etc) comes into contact with the lens surfaces.
