Is doing eye exercises harmful to your eyesight? Over the years, the distinctive melody of eye exercises has accompanied generations of students to spend a wonderful youth time, and it has even become a part of youth memories. Recently, there is a debate about whether eye exercises can effectively prevent myopia. Some people think that it can't prevent myopia, but it may also be harmful. Then-on the eve of May Day, some media quoted relevant scholars as saying that doing eye exercises can not only prevent myopia, but also may be harmful to vision, which surprised many generations who grew up with eye exercises. Tang Xiao, a sophomore in a university, said: "I was surprised to see that eye exercises are harmful to my eyesight." I grew up doing eye exercises. I feel that I have been watching for a long time, and my eyes feel particularly comfortable after doing eye exercises. I am convinced of its role in protecting my eyesight. "So, is China's high myopia rate related to doing eye exercises? According to a survey, the number of myopia patients in the world has been increasing steadily in the past ten years. According to the report of the World Health Organization (WHO), 20% of children in the world need to wear glasses, and the proportion is higher in some countries. Experts believe that about 50% of children in Singapore are nearsighted; In Japan, it is estimated that two-thirds of teenagers aged 17 are nearsighted. " According to incomplete statistics, at present, the number of people with myopia in China accounts for 40%, of whom 20% wear glasses, and some people have not yet discovered or realized the problem of myopia. "Mars, an associate professor at the Optometry Medical Center of Peking Union Medical College Hospital, said," Asia has always been a high incidence area for myopia, especially in China, Japan and South Korea. The myopia rates of these three countries are among the top three in the world. In recent years, the number of people with myopia in Asia has increased. At present, scientists have not found the original reason for the increase of myopia and hyperopia. "Mars said. She believes that there are many reasons for myopia, and now, there is no recognized conclusion in the medical community all over the world. Generally speaking, hereditary myopia accounts for a large part, and at least 40% of myopia is caused by heredity; Less than 60% of the rest is caused by the day after tomorrow. Living environment, reading habits, eating habits, long-term close work and lack of B vitamins are the common causes of myopia. She further stressed: "In the visual development stage, especially before 13 years old, reading books at close range for a long time, eating too many sweets and lacking B vitamins are particularly prone to myopia. "It is understood that only China is carrying out eye exercises in the world, while the myopia rate of Chinese students ranks second in the world, with 28% for primary school students, 60% for junior high school students and 85% for senior high school students. In the United States, which does not do eye exercises, the myopia rate is only 25%. " However, this does not mean that eye exercises are harmful to vision. Cui, chief physician of Beijing Center for Disease Control and Prevention, said. Cui Xiangyi introduced the development history of eye exercises to reporters in detail. Eye exercises were invented by Liu Shiming, a physical education teacher at Beijing Medical College, in the late 1950s. Teacher Liu has great attainments in Chinese massage. He has eye diseases himself. In his usual exploration, he created a set of eye exercises to treat eye diseases and achieved certain results. At this time, the Beijing Municipal Education Bureau is conducting a vision survey in primary and secondary schools in the city, and the survey results are very worrying. The doctors of the Municipal Health and Epidemic Prevention Station and the leaders of the Education Bureau inquired about Liu Shiming's self-made health exercises, so they actively studied and discussed them, and finally created eight eye exercises. Like interval exercises, eye exercises are mass sports, which can improve people's awareness of eye protection, regulate blood circulation in eyes and head, regulate muscles and improve eye fatigue. ""This set of eye exercises has passed the examination of the director of Beijing Hospital of Traditional Chinese Medicine and director Lu of Guang 'anmen Institute of Traditional Chinese Medicine, which is supported by the theory of traditional Chinese medicine. At their suggestion, the technical and scientific methods of acupoint selection were standardized, and at the same time, the eight sections were changed into five sections. In this way, five eye exercises came out with the support of the Municipal Education Bureau. Since then, Zhang, a professor of ophthalmology at Tongren Hospital, pointed out that eye exercises are beneficial to eye health. This is the position of western ophthalmology authorities. " Cui Xiangyi said. It is understood that Professor Li's inscription on the wall chart of eye exercises in the Third Hospital of Beijing Medical University is: Eye exercises are a kind of massage therapy based on the massage method of meridians and acupoints in traditional Chinese medicine and combined with medical sports, which can relieve eye fatigue and is conducive to the prevention and treatment of myopia. From a medical point of view, doing eye exercises can't prevent myopia. There are many reasons for myopia. It should be said that eye exercises are only a way to prevent myopia, "Li Ying said. I think that no matter which part of the human body, proper health care is beneficial. Similarly, eye exercises can relieve visual fatigue, relax eye muscles, dredge meridians and improve blood circulation in the eyes, so they still have a certain effect on preventing myopia. "Dr. Chen Yueguo, a myopia treatment expert at the Eye Center of Peking University Third Hospital, said in an interview with the media that from the perspective of western medicine, the cause of myopia is the elongation of the axial length of the eyeball. Doing eye exercises can't stop the change of the axial length of the eyeball, so it has no substantial effect on preventing myopia. Chen Yueguo believes that when primary and secondary school students do eye exercises, they can give their eyes a chance to relax, which is the same as using this time to look at the distance and do outdoor sports. " It is worth noting that it is best to do eye exercises under the guidance of professional health care doctors. Attention and methods, don't touch the eyeball, so as not to cause some unnecessary harm. "Mars warned. Mars believes that the myopia of ordinary teenagers mostly belongs to "pseudomyopia", which is a kind of functional myopia caused by overuse of eyes and neuromodulation. However, if spasmolysis is not carried out in time, it will develop into true myopia after a long time. She suggested that to prevent myopia, we must cultivate children's good hygiene habits from an early age. To cultivate their correct writing and reading posture, books and eyes should be kept the same size; Reading time should not be too long; There should be proper light for writing and reading; Conduct appropriate outdoor activities; Don't eat too many sweets; Eat more vegetables, fruits, animal livers and egg yolks containing B vitamins. Myopia itself is not terrible. If you find myopia, you should go to a professional eye center for scientific optometry and glasses as soon as possible, and don't go to an optical shop for glasses casually, so as not to accelerate your development.
