Photochromic glass contains silver ions and copper ions. A simplified version of a redox equilibrium is shown below. In bright sunlight the high energy u.v. light causes silver atoms to form and the glass darkens. When the intensity of the light is reduced the reaction is reversed and the glass lightens. Cu + (s) + Ag + (s) ⇌ Cu 2+ (s) + Ag(s) clear glass dark glass When the photochromic glass darkens
