The Ministry of Education said: nearly half of China’s primary school students are myopic, and more than 80% of high school students are myopic

Abstract: there are many ways to treat myopia, and there are many misunderstandings. For example, some parents abuse drugs for treatment, or are eager to find various therapeutic devices for their children. Many myopia therapeutic instruments on the market have the problems of exaggerated curative effect and false publicity. Most therapeutic instruments have no definite curative effect, only auxiliary function.

data show that the incidence of myopia in children and adolescents in China has increased in recent years, and it has increased significantly with age. In 2010, the national physique monitoring bulletin made by the State Sports Administration showed that the prevalence of myopia among Chinese primary school students was 31.67%, 58.07% among junior middle school students and 76.02% among senior high school students. By 2014, the results of the “national survey on students’ physique and health” of the Ministry of education showed that the detection rate of poor eyesight of Chinese primary school students reached 45.71%, 74.36% of junior middle school students and 83.28% of senior high school students. The data also show that the myopia rate of Chinese teenagers is much higher than that of European and American students.

the causes of myopia are mostly related to genetics and nutrition.

in November 2016, the national health and Family Planning Commission, the Ministry of education and the State Administration of sports jointly issued the guiding opinions on strengthening the prevention and control of myopia among children and adolescents, requiring to strengthen the prevention and control of myopia among children and adolescents. What are the causes of

and

myopia? Why is the myopia rate particularly high in China? Yu Xiaoyi explained in combination with scientific research results in recent years.

and

Yu Xiaoyi pointed out that heredity, environment and the interaction between heredity and environment are the mainstream explanations for the causes of myopia in the academic circles.

and

studies show that heredity plays an important role in the formation of refractive state, especially myopia. Incidence rate incidence rate of myopia is far higher than that of Europe and America. For example, the incidence of myopia in black race is the lowest in the world. Two, myopia is the most common problem in the world. For example, the incidence of myopia in China and Japan is much higher than that in Europe and America. For example, the incidence of myopia in black race is the lowest in the world. China’s myopia is two. It has a certain genetic tendency and coding, and is determined by multiple factors. ”

and

. In terms of environmental factors, the most familiar one is the “near industry theory”. This theory holds that juvenile myopia is an acquired myopia caused by too much close work such as reading and writing, or the incidence of myopia is closely related to close work. At present, this statement has also gained consensus in the academic circles.

in addition to heredity and eye habits, physique and nutrition are related to the occurrence of myopia. The incidence of myopia in patients with gastroptosis, renal ptosis and flatfoot is also higher than that in normal people; Teenagers who like snacks, sweets and dental caries have a high incidence of myopia, which may lead to abnormal refraction due to improper food matching.

“in general, genetic factors and near eye work are two important factors affecting the occurrence and development of myopia, and nutrition and physique may also become inducing factors.” Yu Xiaoyi said.

[hot issues]

ask: do you need to wear glasses often?

answer: it depends on the specific degree of

when a child is confirmed as myopia, the most common question asked by parents is whether it is better to wear glasses or not? Will myopia get deeper and deeper after wearing glasses?

Yu Xiaoyi pointed out that this can not be generalized. At present, the mainstream view in the industry is that, For diopters below 2.50 (i.e. 250 degree myopia) mild myopia glasses should be mainly used far away and can be taken off when reading and writing. Patients with medium and high myopia should wear them often, but they need to reduce a certain degree as appropriate, which can not only improve vision, but also promote the strengthening of adjustment and convergence function and prevent the occurrence of exotropia. At the same time, the reasons for the deepening of myopia are very complex, which are related to Congenital heredity, acquired environment Racial factors are related, but not directly related to glasses. “Generally speaking, whether myopia patients are treated or wear glasses, whether glasses are often worn or off, and how many degrees they wear should be carefully checked by ophthalmologists and determined in combination with the specific situation of each patient.” Yu Xiaoyi also suggested that teenagers should check their eyes every six months.

ask: is the myopia therapeutic instrument reliable?

A: the myopia therapeutic instrument is only an auxiliary instrument.

and

have many ways to treat myopia, and there are also many misunderstandings. For example, some parents abuse drugs for treatment, or are eager to find various therapeutic devices for their children. Many myopia therapeutic instruments on the market have the problems of exaggerated curative effect and false publicity. Most therapeutic instruments have no definite curative effect, only auxiliary function.

laser surgery is another popular treatment method in recent years. Yu Xiaoyi believes that there are many kinds of laser surgery, which can not be generalized. It depends on which kind of Personal eye conditions are suitable for. But the main premise is eye health. If high myopia has caused lesions, even surgery is difficult.

[experts talk] how to prevent myopia?

first “cast a good fetus”,

and

How should myopia be prevented and treated? Yu Xiaoyi humorously summarized it as the following points. Step 1: cast the tire. Heredity is an important factor in myopia. Step 2: multi-point outdoor activities to control environmental factors. If there is no choice in the first step, we should make efforts in the environment, including paying attention to the eye environment, more outdoor activities, etc. Outdoor activities are not only conducive to physical health, but also conducive to eye health. Step 3: eat healthy. Step 4: see a doctor and look for professional treatment. Step 5: do more visual rehabilitation to prevent myopia.
