The difference between polarized sunglasses and non-polarized sunglasses：
1. Non-polarized sunglasses generally only have two basic functions of blocking strong light and filtering ultraviolet rays, and the efficiency of filtering ultraviolet rays is low. In our daily life, in addition to strong light and ultraviolet light, when the light passes through uneven roads, water surfaces and other places, it will also produce irregular diffuse reflection light, which makes the eyes blurred and fatigued.
2. Polarized sunglasses can filter out this kind of light, only absorb the reflected light of the object itself, and truly present what you see, making the field of vision clearer, thereby reducing visual fatigue. In addition, polarized sunglasses, due to their high-efficiency filter layer, block ultraviolet rays up to 99%, which can effectively reduce the damage of ultraviolet rays to the eyes.
3. When judging whether the sunglasses is a polarizer, you can rotate the sunglasses upward 45 °. If the color of the lens changes at this time, after turning the sunglasses back to the original position, the color returns to normal, then it can be judged that the sunglasses are polarized. If you can't see the color change of the sunglasses lens no matter how you turn it, you can judge that the sunglasses are not polarized.
The role of polarized sunglasses:
The glare, scattered light and refracted light can be effectively filtered, and only the reflected light of the object itself can be absorbed to truly present what is seen. Therefore, polarized sunglasses can improve people's vision, reduce eye fatigue, and thus play a role in eye care and eye protection. In addition, the polarizer can block all ultraviolet rays, so that people can avoid ultraviolet rays.
