The Principle Of Polarized Sunglasses

- Aug 14, 2019-

Sunglasses are also an indispensable eye in our lives. Whether it is spring, summer, autumn and winter, as long as it is sunny and sunny, we will see some people wearing sunglasses to block the sun from shining on the eyes. People who buy sunglasses often should have heard of polarized sunglasses. What is polarized sunglasses? What are the benefits of wearing polarized sunglasses? I will give you a specific introduction today. 

Polarized sunglasses are made according to the principle of polarization, giving another layer of protection. Because polarized sunglasses add a polarizing film layer to the lens, it is possible to use the polarization to guide the light direction to remove the messy light entering the human eye and to prevent glare. 

The polarized light is formed by waves that are all vibrating in the same direction, and the general light is formed by waves that are not directional vibration. In general, reflected light is an orderly light. The polarizing film layer in polarized sunglasses has a strong filterability for such reflected light, and this lens only allows polarized waves vibrating in a certain direction to pass. The reflected light on the road surface is a kind of special reflection light, which is manifested in the disorder of the light. The polarizing film layer in the polarized sunglasses can function, and it does not allow the light waves vibrating in parallel with the road to pass. In fact, the long molecules of the filter layer are directed horizontally and absorb horizontally polarized light. In this way, most of the reflected light is eliminated, and the overall illumination of the surrounding environment is not reduced. 

In addition to some reflected light, harmful light in life has the most mentioned ultraviolet light. The UV-resistant film in polarized sunglasses is effective against UV rays and protects the eyes.
