Coloured photochromic glasses: the lens changes from clear to red/blue in response to the intensity of ultraviolet radiation, and the visual light transmission of the photochromic lens is from 85% to 15%. They are activated by UV rays and darken when exposed to the sun to protect your eyes from sunlight and glare. When the light gets darker or you go into the house, the lenses will become clear again.
