Recently, a regulation in a primary school in Hangzhou that "students whose eyesight is less than 5.0 cannot be rated as three good students" has aroused heated discussion. Many netizens said, "I was so scared that I immediately threw away the book", "This is discrimination against people born with myopia" and "Learning or not learning is a problem".
The situation of myopia among teenagers in China is not optimistic.
On April 20 19, the myopia survey of children and adolescents in China was released at the press conference held by the National Health Planning Commission. The results show that the overall myopia rate of children and adolescents in China is 53.6%, with an average of one myopia in every two people. The myopia rate of senior one students is 15.7%, which will increase to 59.0% in grade six. High myopia (myopia degree over 600 degrees) accounts for 2 1.9% of the total myopia. The latest research report of the World Health Organization shows that the number of myopia patients in China is as high as 600 million, ranking first in the world!

Faced with such a situation, the public can't help wondering, haven't we been doing eye exercises? Why are so many people nearsighted?
Eye exercises are "useful" and "useless"
From small to large, whether it is the subtle influence of various propaganda information or the discrimination of self-awareness, it tells us that eye exercises can prevent myopia, but it does not rule out the view that eye exercises are useless. 20 12 in Weibo, a netizen published an article on the "uselessness" of eye exercises, which pushed eye exercises to the forefront: "Eye exercises have harmed young people in China for 49 years, and massage has no effect on acupoints. Over the past 49 years, the myopia rate of Chinese teenagers has risen to the second place in the world, reaching 360 million. Doing eye exercises can't improve eyesight. Many students massage with dirty hands, which leads to pinkeye and eye infection.
From the medical principle, most myopia is due to long-term overuse of the eyes, which makes the eyes in a state of tension for a long time and the length of the eyeball axis becomes longer. After the parallel light passes through the refractive system of the eyeball and focuses on the retina, it becomes myopia. Obviously, doing eye exercises can't stop the change of axial length, and can't effectively prevent the formation and development of myopia. Therefore, it has no substantial effect on treating myopia.

Although eye exercises cannot treat myopia, they can temporarily relieve eye fatigue. On the one hand, when doing eye exercises, closing your eyes can make your eyes rest temporarily; On the other hand, massaging acupoints around the eyes can dredge meridians, improve and promote blood circulation in the eyes, and eliminate and adjust eye tension; In addition, eye exercises and soothing music can also relieve mental stress to some extent.
As far as personal experience is concerned, after doing eye exercises, I really feel that my eyes are much more comfortable and my vision seems to be clearer.
In addition, some literature reports also verified this point. Teachers from the School of Acupuncture and Massage of Shanghai University of Traditional Chinese Medicine conducted an intervention study on 1 16 cases (202 eyes) of juvenile mild myopia, and observed the changes of vision with the international standard visual acuity chart two months later. The results show that the effective rate of eye exercises for mild myopia is as high as 85.4%. An article in Medical Theory and Practice (No.10, No.20 15) about the preventive effect of new eye exercises on students' poor eyesight also observed similar results, and the total effective rate of new eye exercises was 86.4%.
Is eye exercises harmful? This pot of eye exercises is not easy to recite.
For the saying that eye exercises are harmful, most of them emphasize that "massage with dirty hands leads to pinkeye and eye infection." This is a health problem caused by dirty hands, and this pot of eye exercises is not good for the back.
You may have done "fake" eye exercises.
By massaging the acupoints around the eyes, eye exercises are effective. However, the survey on the irregular operation of students' eye exercises conducted by China School Hygiene shows that many students are irregular in doing eye exercises.

The statistical results show that more than 80% of the 1662 primary school students and 1458 middle school students don't know the strength of operation, how to find holes and basic techniques. No wonder many literature reports are inconsistent with the actual results, which requires primary and secondary school teachers to strengthen the standardized training of eye exercises, so that eye exercises can really play their due role.
How to prevent myopia?
In fact, to fundamentally prevent myopia, we should start from standardizing daily behaviors and habits. With the popularity of various electronic products, many young people are becoming low-headed people and night owls, and they always insist on playing mobile phones before going to bed at night, which has become a new important factor leading to myopia. Therefore, when studying, you must sit up straight and keep your head straight. When using eyes, you must read or write in a well-lit environment for half an hour to 1 hour. You should observe for a few minutes or close your eyes and have a rest. In addition, don't play computer or watch mobile phone for a long time at ordinary times, and keep your eyes at a certain distance from the fluorescent screen. Only by maintaining good eye hygiene can we avoid the trouble of myopia.
