Principles of Polarized Sunglasses

Polarized light can be divided into three types: linearly, elliptically, and circularly. Generally, the so-called polarized light is linearly polarized light, that is, plane-polarized light. The propagation direction of the linear polarization and the vibration plane are called the vibration plane. And the inclusion plane of the vertical vibration and the transmission direction is called the polarization plane. Sunglasses can block the uncomfortably bright light, which can protect the eyes from the harmful effects of ultraviolet rays. When certain wavelengths of light (UVA, UVB, and sometimes infrared) pass through the lens, they cancel each other out on the inside of the lens, toward the eye. The overlapping of light waves is not accidental. The combination of the crest of one wave with the trough of its nearest wave results in a cancellation. Polarized sunglasses offer another mechanism for eye protection. The reflected light of asphalt is a special kind of polarized light. The difference between this reflected light and light coming directly from the sun or from any artificial source is a matter of order. Polarized light is made up of waves that vibrate all in one direction, but ordinary light is made up of waves that vibrate not in one direction.

Why is the car glass colored with polarized sunglasses?

Because car glass is coated, polarized sunglasses can see things that are invisible to the naked eye. Car film is usually a metal film, and there is a layer of the metal layer. When you look at it with a polarized lens, you see some colored streaks or colored light.

Why does glass change color when you use polarized sunglasses?

Usually, sunglasses only use the effect of reducing light. Polarized lenses can completely cut off glare caused by many factors like scattering, bending, reflection, and glare due to the nature of polarized light. And ultraviolet light, which can be harmful to the human eye, is completely blocked. So they can make the eyes in outdoor activities are not easy to fatigue, to achieve the real protection function. They can see things more clearly. If you look at the LCD inside the car, it changes color. Another function of polarized sunglasses is to check if the mounting force of the glass is balanced. That's normal. Good polarized sunglasses allow the eye to look directly at the sun at night.
