Product Introduction
Polarized sunglasses selectively absorb the local band that makes up the sun's rays because it relies on very fine metal powders (iron, copper, nickel, etc.). In fact, when light hits the lens, the light is diminished based on the so-called "destructive intervention" process. That is to say, when light of certain wavelengths (herein referred to as ultraviolet light a, ultraviolet light b, and sometimes infrared light) passes through the lens, they cancel each other in the direction of the inner side of the lens, that is, toward the eye. The mutual stacking of light waves is not an occasional phenomenon: the peaks of a wave are combined with the waves of the waves that are close to them, causing each other to cancel each other out. The destructive intervention depends on the refractive index of the lens (ie the level at which the light deviates from the air through different substances) and also depends on the thickness of the lens.
