There are countless idioms about the eyes, such as dazzling eyes, intense energy, and clear ears and eyes... The importance of the eyes to people goes without saying much. But in daily life, people have many bad eye use behaviors. Wrong practice 1: People often stay up late to play Tiktok, games, and dramas when watching mobile phones in dark places or when turning off the lights. Even when the lights are turned off, people are reluctant to put down their mobile phones. Regarding this, Fu Jing, director of the Department of Strabismus and Pediatric Ophthalmology at Beijing Tongren Hospital affiliated with Capital Medical University (hereinafter referred to as Beijing Tongren Hospital), said that reading a mobile phone belongs to close range use, and combined with dim light, it is highly likely to cause or worsen myopia. However, such behavior may also lead to more serious consequences. Duan Xuanchu, the director of Changsha Aier Ophthalmology Hospital, said that playing with your phone in the dark, "Glaucoma is quietly approaching you. Duan Xuanchu said that generally speaking, the causes of glaucoma include genetic factors, bad lifestyle habits, and eye problems. Watching a mobile phone in a dark environment is very harmful to the eyes. The screen brightness of the mobile phone will have a clear contrast with the surrounding dark environment, which will increase the irritation to the eyes and damage the normal structure of the eyes. It will not only lead to a rapid deepening of myopia, but also cause an increase in intraocular pressure, affect the circulation of liquid in the eyes, increase the sense of eye fatigue, and even induce acute glaucoma. "Of course, playing with mobile phones in the dark is just an inducement. The most important thing is that individuals themselves belong to the 'glaucoma quality'." Duan Xuanchu explained that "glaucoma quality" mainly refers to people with high myopia, hyperopia and a family history of glaucoma. Once these people have a trigger, they are prone to developing glaucoma. However, even if you have the "glaucoma quality", don't be afraid. As long as you use your eyes scientifically and prevent them reasonably, the probability of glaucoma onset or blindness will be much lower. Fu Jing said that the correct approach is to keep the indoor background light sufficient when looking at the phone, maintain a certain distance from the phone, and adjust the screen to the appropriate brightness. After watching for 30 minutes, take a 5-10 minute break by looking into the distance. Doing eye exercises and looking far away are all good eye care methods, "said Fu Jing. Wrong practice 2: Do not take eye protection under strong light. In hot summer, when the sun is shining brightly, some people may apply sunscreen before going out, but do not take any protective measures for their eyes. Regarding this, Zhang Xinyuan, the chief ophthalmologist of Beijing Tongren Hospital, said that doing so poses significant harm to the eyes. Among them, short wave near-infrared with short wavelength and strong penetrability may cause damage to the lens and retina, while long wave near-infrared with weak penetrability mainly causes corneal and lens damage. Ultraviolet rays mainly damage the cornea and lens, as well as the retina and vitreous body. Generally, after 3-8 hours of ultraviolet radiation, the eyes will experience a strong foreign body sensation like entering sand, accompanied by obvious symptoms such as tingling, photophobia, tearing, and inability to open. Not taking eye protection under strong light can also lead to cataracts. Dr. Li Xiaoman from the Eye and Optometry Hospital affiliated with Wenzhou Medical University said that the lens of the eye can absorb ultraviolet rays and protect the retina, but ultraviolet rays can also accelerate the aging of the lens, gradually making it turbid, increasing the probability of developing cataracts, and leading to early occurrence of cataracts.
