What are polarized sunglasses?

Outdoor driving, fishing, golf, mountaineering, skiing, sightseeing, etc. Wearing sunglasses can be seen everywhere, which not only protects the glasses from ultraviolet radiation, but also adds luster to your image. But for most of the newcomers, what are polarized sunglasses and what do polarized glasses mean? These meanings may not be understood. Today, I will give you a general introduction. 9105 Polarized Myopia Sunglasses Polarized sunglasses can block uncomfortable glare, and at the same time can protect the eyes from ultraviolet rays. All this is due to the metal powder filter, which can 'select' the light when it hits it. AIKUSTE polarized sunglasses can selectively absorb some of the wavelengths that make up the sun's rays because they use very fine metal powders (iron, copper, nickel, etc.). In fact, when light hits the lens, the light is reduced based on the so-called 'destructive interference' process. In other words, when certain wavelengths of light (herein referred to as ultraviolet a, ultraviolet b, and sometimes infrared) pass through the lens, they will cancel each other out on the inside of the lens that is toward the eye. The overlapping of light waves is not accidental: the peaks of a wave and the troughs of the adjacent waves combine to cancel each other. The phenomenon of destructive interference depends on the refractive index of the lens (that is, the degree of deviation when light passes through different substances in the air), 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. Polarized sunglasses provide another mechanism for eye protection. The reflected light from the asphalt road is relatively special polarized light. The difference between this reflected light and the light directly from the sun or any artificial light source lies in order. Polarized light is formed by waves that vibrate all the way in one direction, while ordinary light is formed by waves that vibrate non-directionally. This is like a group of people walking in disorder and a group of soldiers marching in order, forming a sharp dialogue. This is like the original blinds, the light comes in from one direction, removing the messy light, so the field of vision will be clear. Polarized sunglasses are suitable for fishing, driving, sports, sailing, skiing, hunting and other occasions. Related Reading: Polarized Sunglasses
