Abstract: the “useless theory” of eye exercises is mainly based on the fact that the myopia rate of teenagers has been rising in recent 50 years, which has ranked second in the world. On the contrary, countries such as the United States do not do eye exercises, but the myopia rate of students is much lower than that of Chinese students.
in 2006, Fang Zhouzi said in the media that “eye exercises are pseudoscience”. Therefore, the “useless theory” of eye exercises, which has been popularized for more than 50 years, was questioned by students, parents and teachers. The advantages, disadvantages and retention of eye exercises have become a topic of public concern. The “useless theory” of
eye exercises is mainly based on the fact that over the past 50 years, the myopia rate of teenagers has been rising and has ranked second in the world. On the contrary, countries such as the United States do not do eye exercises, but the myopia rate of students is much lower than that of Chinese students. Obviously, it is unscientific to consider only the incidence rate of myopia without considering race differences and eye behavior differences.
are the least racial race of black race, and the incidence rate of white race is high. In China, the prevalence rate of Han nationality is the highest, followed by Bai nationality, less Uighur nationality, Kazak nationality and so on. From the perspective of eye behavior, American students have less academic burden than Chinese students, and their time to read closely will be reduced. Of course, in addition, the genetic factors and electronic screen contact time of children in the two countries are also different. Therefore, it is useless to simply blame eye exercises because the myopia rate of Chinese students ranks second in the world!
as long as they are operated correctly, eye exercises can alleviate visual fatigue by relaxing eye muscles, dredging meridians and activating collaterals, improving eye blood circulation and nerve function. They play a positive role in eye health and are proved to be beneficial to the prevention and treatment of myopia. Through objective research, it is found that after eye exercises, there are positive changes in naked eye vision, eye fatigue work index, eye blood flow velocity, eye blood flow resistance index and so on.
however, we can’t expect 10 minutes of eye exercises every day to protect our eyes for more than 10 hours every day. This is impossible. Therefore, in addition to doing eye exercises, we should scientifically arrange the time of eye use. What worries us most is that even for 10 minutes of eye exercises, young people have not seriously completed, failed to find the acupoints, and do not necessarily follow the standard actions. Whether eye exercises are correct, serious and lasting is the decisive factor of whether they are useful or not! The role of eye exercises is gradual and cumulative. Naturally, it is also a process of qualitative change caused by quantitative change.
to sum up, heredity and overuse of eyes are the main causes of myopia. Parents, teachers and students must believe in the scientific and positive role of eye exercises. Persistence has an effect. Habits accumulate over time. Eye care also needs to be adhered to day after day. Experts appeal that if you can’t shorten the time of using eyes, Then eye exercises must be beneficial and harmless.
