Lenses are made from photochromic material, which darkens upon exposure to high-frequency light, like UV rays from the sun. Lenses change back to a clear state under low, ambient light conditions. Lined with a special coating, the lenses also filter and block out a degree of blue-violet and LED light emitted from digital screens like computers, tablets and cellphones.
