provides sunglasses testing and certification services

sunglasses can selectively absorb part of the band that makes up the sun's rays because they use very fine metal powder (iron, copper, nickel, etc.). In fact, when the light shines on the lens, the light is reduced based on the so-called "destructive interference" process. That is, when certain wavelengths of light (in this case, ultraviolet a, ultraviolet B, and sometimes infrared) pass through the lens, they cancel each other out on the inside of the lens, I .e., in the direction toward the eye. The mutual overlap of light waves is not an accidental phenomenon: the crest of a wave and the trough of a wave close to it cause mutual cancellation. The destructive interference phenomenon depends on the refractive index of the lens (that is, the degree to which light deviates from the air when passing through different substances) and also depends on the thickness of the lens. Generally speaking, the thickness of the lens does not change much, and the refractive index of the lens varies according to the difference in chemical composition.
