What are polarized lenses for?
Polarized lenses contain a layer of polarizing plates in which molecular chains form a light-grating structure in which dichromatic pigments, which absorb polarized light, are evenly distributed. A beam of light is absorbed when it vibrates in the same direction as the bars of the molecular chain of the polarized lens. The grating direction formed by the molecular chain of the polarizer is the axial direction of the polarizer, which is generally horizontal. When polarized lenses are worn, they absorb all the light that vibrates horizontally, thus absorbing the glare and preventing it from reaching the eyes.
