Myopia has nothing to do with eye exercises. What is the real reason

Abstract: most of the problems of Chinese teenagers’ myopia refer to the myopia caused by acquired factors. This kind of myopia is the so-called simple myopia, also known as “school myopia”. It is generally believed that it is mainly caused by the environment and their own behavior. It is an important factor causing children’s and teenagers’ myopia at present.

recently, a “useless theory of eye exercises” on the microblog attracted attention and heated discussion. Microblogging pointed out that doing eye exercises for 49 years is useless and impairs people’s eyesight. In this regard, experts show that eye exercises can alleviate fatigue and have a certain scientific basis. Pressing the right acupoints is still helpful to the eyes. Recently, netizens of

and

said in their microblogs that, “Eye exercises have harmed Chinese teenagers for 49 years. In the world, only China has done eye exercises and massaged useless acupoints. In the past 49 years, the myopia rate of Chinese teenagers has risen to the second in the world, reaching 360 million people. Eye exercises can not improve their eyesight. Many students massage with dirty hands, resulting in red eye disease and eye infection. Eye exercises were carried out by Liu Shi, Physical Education Department of Beijing Medical College in 1963 Director Ming created it himself, and the result was forced to be implemented throughout the country, which has no scientific basis. ” In fact, Fang Zhouzi also wrote in 2007 that doing eye exercises is not completely harmless. He often touches and rubs his eyes with unclean hands, which increases the risk of eye infection and even respiratory tract infection, because the virus will enter the upper respiratory tract from the nasolacrimal duct.

Fang Zhouzi’s view five years ago is reasonable, because simply relying on the promotion of eye exercises can not play the role of preventing myopia. Because eye exercises are at most an introduction, I hope to draw people’s attention to the care of eyesight. However, it can be said that this intention has not been realized, because the pressure brought by the change of social environment has led people to put vision problems in a secondary position.

most of the problems of Chinese teenagers’ myopia refer to the myopia caused by acquired factors. This kind of myopia is the so-called simple myopia, also known as “school myopia”. It is generally believed that it is mainly caused by the environment and their own behavior. It is an important factor causing children’s and teenagers’ myopia at present. At present, almost all people in the industry generally believe that the causes of simple myopia are: poor eye environment, such as insufficient light, dirty atmosphere, narrow visual space, frequent flickering changes of visual objects, etc; Did not develop good eye hygiene habits, such as incorrect sitting posture when reading and writing, staying in bed for a long time, reading, watching TV, surfing the Internet for a long time, playing computer games, etc; In addition, heavy learning burden, high psychological pressure, unreasonable nutritional structure, lack of due outdoor activities and physical exercise, etc. are also the reasons for students’ myopia.

myopia don’t rely on eye exercises. The myopia rate of Chinese students is only second to that of Japan. The myopia rate of Chinese students has soared to the second in the world in this century, second only to that of Japanese

and

. One of the evidence of netizens shelling eye exercises is that “in the past 49 years, the myopia rate of Chinese teenagers has risen to the second in the world, reaching 360 million people”. According to relevant ancient Chinese literature search, the incidence rate of myopia in China has risen to second in the world, as second only to Japan in 2002. Some surveys even believe that the myopia rate of 50% to 60% of students in China has ranked first in the world, but it is certain that the number of students in China must be the first in the world.

sampling monitoring results of myopia prevention and control of primary and secondary school students in China in 2002 show that the myopia rate of primary and secondary school students is 26. 96%; 53 junior high school students. 43%; High school students are more than 72%; By 2011, the myopia of primary school students was 28%, that of junior middle school students was 60%, that of senior high school students was 85%, and that of college students was 90%. The upward trend continued rapidly.

and

students’ myopia rate soared in the late 1990s: learning pressure surged, myopia was younger, and

and

netizens said that eye exercises had harmed Chinese teenagers for 49 years, which was groundless. Because the myopia rate of children in China was low in the mid-1970s, accounting for about 15% to 20%. It did not rush to 55% or even 80% until 90s. In 1998, the incidence rate of myopia in the world ranked fourth in the world, and increased to second in twenty-first Century. The reason is not difficult to understand: the intensification of social competition has penetrated into the field of school education, increasing the burden on students, resulting in an increasing proportion of students suffering from myopia. In the education reform in the late 1990s, college students no longer assigned jobs after graduation and had to find jobs by themselves, which increased the pressure for students to test well in the school. The survey of

and

shows that the general trend of myopia rate of Chinese students is: it increases with age; Urban students are higher than rural students; Girls are higher than boys; Students in big cities are higher than those in small and medium-sized cities; The students in key schools are higher than those in non key schools. This shows that the myopia rate of students has increased rapidly in recent ten years, which is related to the heavy learning burden and the pressure of entrance examination. Today, many children have reported to a wide range of early education, Mathematical Olympiad and other training classes since kindergarten. Intense learning and great mental pressure have overwhelmed children’s eyes. In the face of great pressure to enter school, it is difficult to implement eye protection measures in place.

scientific research shows that the myopia rate of students in China, Japan and South Korea is high. Due to education and sports,

the myopia rate of Japan, China and South Korea ranks among the top three in the world in the sampling survey of 29 countries in the world. Ian Morgan, a professor at the Australian National University, published an article in the lancet in May this year, saying that the educational tradition and system in East Asia may be the main reason for the high number of myopia students in this region. Poor reading habits and academic pressure are closely related to the occurrence of myopia. East Asia has made remarkable achievements in the field of education, but students seldom enjoy the sunshine because of their heavy burden and lack of outdoor activities.

the report points out that the myopia problem of East Asian students is largely due to the environment rather than genes. The people who are most likely to suffer from myopia are actually people who stay closed, whether they are reading indoors, playing games or watching TV. The Sydney myopia study by Australian scientists found that children with poor reading habits, books too close to their face and too long reading time are more likely to be short-sighted. An appropriate amount of outdoor activity time can help protect eyesight and prevent myopia.
