High Quality 4-Chloromethyl styrene - Photochromic Material – Freemen

Photochromic Material

Photochromic materials are transparent materials which exhibit increased light absorption when they are exposed to light. They can be optical glasses or plastic materials. The photochromic properties usually result from the addition of a photochromic substance to a transparent material.

Typically, such materials are used in sunglasses which automatically adapt to the light conditions: they transmit most light if it is not too bright, but get increasingly dark when exposed to sunlight. The photo darkening can occur within less than a minute; the recovery to the clear state may take several minutes, depending on the temperature.
