Polarized sunglasses are a kind of sunglasses. Polarization can be divided into three kinds, namely, linear polarization, elliptical polarization and circular polarization. The so-called polarized light refers to the linear polarization, also known as plane polarization. The vibration of this light wave is fixed in specific direction, the propagation path in the space is sinusoidal, and the projection on the plane of the vertical propagation direction is a straight line.
The plane of the linearly polarized vibration direction and the propagation direction is called the vibration plane, and the plane of the plane is perpendicular to the direction of vibration and contains the propagation direction. So that natural light through the polarizer, you can get linear polarization, crystal optics study often used.
Polarized sunglasses Production principle:
Polarized sunglasses can block uncomfortable light, while protecting the eyes from UV damage. All of this is due to the metal powder filter, which can be selected when the light enters. Polarized sunglasses can selectively absorb part of the composition of the sun's rays, because it uses very fine metal powder (iron, copper, nickel, etc.)
Polarized sunglasses can be divided according to use: riding mirror glasses, ski mirror sunglasses, fishing sunglasses, polarized driving sunglasses, outdoor sports glasses, golf glasses.
