Because green tints offer the best distinction and biggest visual acuity of any tint, they are very talked-about.

Developed by Corning within the late 1960s and popularized by Transitions in the nineteen nineties, photochromic lenses depend on a specific chemical reaction to UV radiation. By immersing plastic lenses in a chemical bath, the photochromic molecules are actually absorbed to a depth of about 150 microns into the plastic. But when exposed to UV rays in sunlight, the molecules undergo a chemical course of that causes them to alter form. The variety of the molecules that change form varies with the depth of the UV rays.
