It enables people to carry out long-term activities even under strong light, the eyes are not easy to feel tired, the function of real protective glasses is achieved, and the things that can be seen are clearer, and the three-dimensional is more aesthetically pleasing. It has been proved by scientists that ultraviolet rays in the sun can damage the skin, but many people do not know that excessive exposure to ultraviolet rays in the sun can also be harmful to human eyes. Every part of the eye is also damaged in the process of sun exposure, and it will also accumulate. If this continues for a long time, it will have a destructive effect on the cornea, retina, lens, etc., and will lead to cataracts, actinic corneas and other eye diseases. Although wearing sunglasses glasses can avoid such accidents, general sunglasses can only use the function of reducing light, because ordinary lenses cannot filter sunlight, so they can only reduce the intensity of glare, ultraviolet light, etc., and cannot completely block These harmful sun rays, so their function is only to reduce eye damage, and cannot completely prevent people's eyes from being hurt. But the biggest advantage of general sunglasses is that they are popular, so many people are wearing sunglasses. In order to reduce the damage to the eyes, the biased sunglasses came out like this. Like the polarized sunglasses inside, they all have the ability to filter the sun's rays. Completely reduce the damage of glare, ultraviolet light and other strong light.

Polarized sunglasses also have a good effect in the prevention and treatment of ophthalmic diseases, It's not just anti-glare and play a role in dressing up. All in all, the special effect of the polarizer is to effectively exclude and filter the scattered light in the beam. The light can be put into the visual image of the eye on the light-transmitting axis of the right track, so that the field of vision is clearer and more natural, so that people can easily and naturally see the beautiful light in the strong sunlight. It is polarized sunglasses that have this feature, so this feature is used to block harmful light, so that no matter the sunlight touches any object, it will cause harmful glare due to natural reflection or refraction. However, polarized sunglasses can completely absorb these strong lights that can cause glare and eye damage, so that they can truly protect the eyes.
