Genuine polarized sunglasses should be worn comfortably; Poor quality lenses have no technical or functional value when manufactured, and the lens material is also very poor. If you feel uncomfortable, dizzy, headache, dry eyes, and tingling after wearing them, you should immediately stop using them.

The protective function of the frame is that most polarized sports sunglasses have a curved surface design, which can effectively prevent wind and foreign objects from irritating the eyes during outdoor activities. In addition, the hardness of polarized lenses and the flexibility of the glass frame material both consider whether it will cause harm to the human body.

Polarized sunglasses are sunglasses. Polarization can be divided into three types, namely linear polarization, elliptical polarization, and circular polarization. Generally speaking, polarization refers to linear polarization, also known as planar polarization. The vibration of this kind of light wave is fixed along a specific direction, its propagation path in space is a Sine wave, and its projection on the plane of the vertical propagation direction is a straight line.

The plane formed by the vibration direction and propagation direction of linearly polarized light is called the vibration surface, and the plane perpendicular to the vibration direction and containing the propagation direction is called the polarization surface. By passing natural light through a polarizer, linear polarization can be obtained, which is often used in crystal optics research.
