Preventing myopia in children is something that many parents attach great importance to. "I dried my eyelids every day, and my girl's eyesight recovered to 50！The reporter noticed that there has recently been a wave of "eyelids"** myopia craze on the Internet, and even claimed that the degree can be "cleared". Does eyelid tanning really have such a miraculous effect?Xiao Liwei, an attending physician in the Department of Ophthalmology of Nanjing Hospital of Integrated Traditional Chinese and Western Medicine, pointed out that although sun exposure can stimulate dopamine and vitamin D synthesis and effectively reduce the development of myopia, it cannot achieve this effect by simply "drying the eyelids", let alone reducing true myopia.
Netizen posted: I have been exposed to the sun for 13 months, and my vision is 46 back to 50
The reporter found that in recent times, the people who pay attention to "eyelids" on the Internet are mainly parents of the post-80s and post-90s, and the topic of "eyelids" has become a hot search, and the number of readings on related topics has reached hundreds of thousands. The main concern is whether sun-drying eyelids can really make myopia "clear" and whether sun-drying eyelids is harmful.
Xiaohongshu netizen "Lin" wrote in a post that his daughter's physical examination was still 5 when she was in the first grade0 vision, but the physical examination vision at the beginning of the second grade becomes. 7。"Seeing the child's vision decline, I didn't understand it at first, and then I was a little scared. ”
Lin said that because some parents in the child's class took their children to have vision restoration, he also formulated a "vision restoration plan" for his daughter. The reporter noticed that in the plan posted by "Lin", the first item is the so-called "eyelids". "Lin" said that the child closes his eyes and basks his eyelids twice a day, before 9 o'clock in winter and 7 o'clock in summer, for 5 minutes each time. In addition, the "Vision Recovery Program" also includes outdoor sports, covering training, rice character exercises, and more. "The program lasted for about 13 months, and the child's vision returned to 50 up. ”
The reporter noticed that most of the "eyelids" posted on the Internet were similar to those described by "Lin", and the time was in the morning or evening, closing his eyes and facing the sun for 5 to 10 minutes. In general, only the eyelids are exposed on the face, and the other faces are protected by a sunscreen mask, which is claimed to absorb natural red light and act on the eyes, shortening the eye axis. Some parents said that their eyes were warm when they were sunburned, and they felt much more comfortable and clear after sunburning. However, many netizens questioned in the comment area, "Can this really work?" and "I didn't understand the principle of drying eyelids after reading all the comments." ”
Exposure to outdoor light can help prevent myopia.
However, "drying eyelids" to treat myopia is not scientific.
It is not scientific to reduce myopia by drying eyelids. Xiao Liwei, an attending physician of the Department of Ophthalmology of Nanjing Hospital of Integrated Traditional Chinese and Western Medicine, said in an interview with reporters that the main causes of myopia are genetics, excessive use of near eyes, and reduced outdoor activities. Myopia in adolescents can be intervened, and sun exposure can stimulate dopamine and vitamin D synthesis, effectively reducing the development of myopia. However, simply drying the eyelids cannot achieve this effect, let alone reduce true myopia. At the same time, the eyelids are relatively thin, and high-intensity ultraviolet radiation may cause damage to the cornea and lens.
In Xiao Liwei's view, moderate outdoor light can help prevent myopia. For example, children and adolescents should maintain more than 2 hours of outdoor light every day, and no less than 10 hours of outdoor light a week, reduce the time and intensity of near eye use, and help prevent myopia. And these do not mean that simple "eyelids" can be equated with myopia and vision restoration. Experts remind that protecting your eyes requires a balanced diet, less sweets, and adequate sleep are also necessary factors to protect your eyesight. More than 10 hours of sleep for elementary school students, 9 hours for middle school students, and 8 hours for high school students can help with eye health. "In general, myopia prevention requires a combination of prevention and treatment, and it still requires reasonable eye intensity, sufficient outdoor exercise, standardized diagnosis and treatment of integrated traditional Chinese and Western medicine, and the establishment of eye health records," Xiao Liwei said.
Experts emphatically remind that early behavioral intervention is the most valuable in the prevention and treatment of myopia. Use your eyes up close for 20 minutes, preferably 6 meters away, for more than 20 seconds. In addition, the previously released "Clinical Practice Guidelines for Appropriate Traditional Chinese Medicine Techniques for the Prevention and Control of Myopia in Children and Adolescents" recommended 9 appropriate techniques of traditional Chinese medicine with conclusive evidence, such as acupuncture, auricular pressure pills, moxibustion, and acupressure, which are also helpful for the prevention and control of myopia in traditional Chinese medicine.
