Is the red lens of sunglasses good for glasses?

The weather is getting hotter and the ultraviolet rays are strong. People like to wear sunglasses when traveling, especially young people. They not only like to wear sunglasses, but also hope that the styles of sunglasses are unconventional and the lenses are brightly colored. It is worth noting that it is best not to wear sunglasses with red lenses, otherwise you will get eye diseases such as cataracts. In recent years, the cataract patients in the eye clinic are younger, and the high incidence of the disease is in summer every year. The reason may be caused by sunglasses. Professor Li Yuehua from the Geriatrics Center of Xiyuan Hospital of Chinese Academy of Traditional Chinese Medicine explained that the human body has an instinctive reaction to protect itself. When the eyes encounter strong light, the pupils will naturally contract, and the intensity of ultraviolet rays passing through will also be weakened. Although sunglasses don't have the function of isolating ultraviolet rays, their pupils will shrink a lot because of weak light. At this time, in the face of the invasion of ultraviolet rays, the eye door is wide open, and its damage can be imagined. Clinically, some patients often suffer from cataract and other related diseases because of wearing inappropriate or inferior sunglasses. Therefore, everyone should choose sunglasses produced by regular manufacturers, and the colors can be green, gray, brown and so on. Medium depth. It is best not to choose red, because red lenses have the worst absorption effect on ultraviolet rays and cannot protect eyes. In the past, the onset age of cataract was 50-60 years old. In recent years, the survey shows that the proportion of patients aged 30-40 is gradually increasing, and the total number of young patients is increasing at a rate of about 10% every year. Cataract is no longer a patent for the elderly. Professor Zhu Siquan, director of the Cataract Center of Tongren Hospital, said that young people still have problems such as heavy work pressure, working at computer desks for a long time and frequent use of mobile phones, which will lead to younger cataract. It should be noted that the early symptoms of cataract are not only decreased vision, but also decreased visual field, stereoscopic vision, color discrimination, aberration, reading speed and eye adaptability. Once the cataract is diagnosed, the earlier the operation, the better. Zhu Siquan said that it used to be thought that cataract could only be operated when it was mature, but with the maturity of technology, the earlier the operation, the less trauma.
