The lenses contain photochromic molecules that undergo a chemical reaction when exposed to UV radiation, causing them to darken. The degree of darkening depends on the intensity of the UV radiation and some of photochromic molecules present in the lenses.

Lecheng Polarized Lenses
Polarized lenses are a type of sunglass lenses that reduce glare and eyestrain caused by reflected light. They have a special chemical applied to them to filter light, which blocks horizontal light waves bouncing off a smooth surface such as water or a car hood. This filtering creates vertical openings for light, allowing only light rays that approach your eyes vertically to fit through those opening. As a result, the image you see with polarized lenses is a bit darker than usual, but objects look crisper and clearer, and details are easier to see.
-
