Polarized lenses
1. Polarized light (polarized) Sunglasses provide another mechanism to protect the eyes. The reflected light from asphalt roads is a special polarized light. The difference between this reflected light and the light directly from the sun or any artificial light source lies in the problem of order. Polarized light is formed by waves that vibrate in one direction, while ordinary light is formed by waves that vibrate in an undirected direction. This is like a group of disorderly and random people and a group of soldiers marching in neat steps, they form a distinct antithesis. Generally speaking, reflected light is a kind of orderly light. Polarizing lenses are particularly effective in blocking this light because their filterability plays a role.
2. Polarized sunglasses can block the uncomfortable strong light and protect eyes from ultraviolet rays. All this is due to metal powder filtration devices, which can"select"light when it enters. Colored glasses can selectively absorb part of the wavebands that make up the sunlight, It is because it uses very fine metal powders (iron, copper, nickel, etc.). In fact, when light shines on the lens, the light is reduced based on the so-called"destructive interference"process. That is, when the light of certain wavelengths (this refers to ultraviolet A, ultraviolet B, and sometimes infrared) when passing through the lens, they will cancel each other on the inner side of the lens, that is, towards the eye. The overlapping of light waves is not accidental: the peak of a wave and the trough of the wave close to it will cancel each other. The cancellation interference phenomenon depends on the refractive index of the lens (that is, the degree of deviation of light passing through different substances from the air) also depends on the thickness of the lens. Generally speaking, the thickness of the lens changes little, and the refractive index of the lens varies according to the difference in chemical composition.
