Polarized sunglasses are manufactured according to the principle of the polarization of light, in addition to anti-ultraviolet, and reduce the intensity of light, but also can effectively filter out glare (belong to a kind of sunglasses).
Ordinary sunglasses are often used to block sunlight and ultraviolet rays to reduce eye fatigue and damage caused by strong light stimulation.
Polarizer is the principle of polarized light, the object seen will not change color. The vehicle is driving at high speed, after entering the tunnel, wearing ordinary sunglasses in front of a piece of light immediately dimmed, serious can not see the road in front, and the polarizer will not have an impact.
2, the difference in the degree of blocking ultraviolet light
The UV blocking rate of the polarizer reaches 99%, while the blocking rate of the ordinary dyed lens is quite low.

One of the functions of the polarized lens is to filter out glare, scattered light, and refracted light, absorb only the reflected light of the object itself, and truly present what is seen so that the driver can improve vision, reduce fatigue, increase color saturation, and have a clearer vision.
Ordinary sunglasses take the color of the dyed lens to weaken the light into the eye, but glare, refracted light and scattered light enters the eye, and can not achieve the purpose of eye candy.
Polarized sunglasses or ordinary sunglasses which is better
