Since the sun's rays reaching the earth's surface contain ultraviolet rays, the cornea and crystals of the human eye are the most vulnerable to ultraviolet damage, and "cataracts" are eye diseases closely related to them. Due to the destruction of the ozone layer by the environment and the increase in outdoor activities in summer, the damage of ultraviolet rays to the human eye cannot be ignored. Wearing sunglasses is a good way to protect your eyes from UV damage. For the strong sunlight in summer, people's eyes sometimes can't be parried, because when the eyes receive too much light, it will naturally shrink the iris, and some irritating light may damage the retina. And a pair of good sunglasses can filter up to 97% of the eye light to protect the eyes from harm. Ultraviolet rays can damage the cornea and retina, and high-quality sunglasses can completely eliminate ultraviolet radiation.
