In recent years, the problem of myopia among adolescents in China has shown a trend of high incidence, younger age and more serious. According to the data of the National Health Planning Commission, in 20 18 years, the overall myopia rate of children and adolescents in China was 53.6%. In 2020, the data of adolescent vision survey released by the Ministry of Education showed that,
During the epidemic in COVID-19, the myopia rate of primary and middle school students in China increased 1 1.7% compared with 20 19 years, and the myopia rate of primary school students increased 15.2%. In the world, myopia is also the most common eye disease among teenagers.
According to the World Vision Report released by WHO, the global myopia population is 2.6 billion, including 3 1.9 children, and the incidence of myopia is relatively high in East Asia. The occurrence and prevention of myopia is long-term and cumulative, which is not easy to attract attention and has misunderstandings. Myopia is a chronic eye disease, and the development of vision presents a long-term changing process.
It is precisely because the harm of myopia is not easy to detect immediately, and wearing glasses can control the purpose, which makes the society not know enough about the harm of myopia and pay insufficient attention to the prevention and treatment of myopia. Although myopia is a chronic disease, it is harmful. Myopia is usually accompanied by astigmatism, glaucoma and other symptoms, while high myopia has many complications such as macular and retinal detachment.
Increase the probability of students suffering from cataracts in adulthood, which will lead to blindness in severe cases. Myopia will not only bring inconvenience to daily life, but also cause continuous correction costs and increase the economic burden of poor families. Parents have misunderstandings about myopia prevention and treatment. In the minds of some parents, myopia is a normal physiological phenomenon and can be prevented by wearing glasses.
However, frame glasses only play a corrective role and have no effect on myopia. Unreasonable wearing glasses will aggravate myopia. Some parents think that "laser surgery can be done once and for all", but laser surgery can only correct vision, achieve the purpose of taking off glasses, can not cure fundus diseases, nor can it reduce the risk of blindness.
In addition, myopia correction surgery belongs to medical cosmetic plastic surgery, which is not covered by medical insurance reimbursement, which deepens the misunderstanding that "myopia is not a disease" to some extent. September, 2020 10, students of experimental primary school in Shaowu City, Fujian Province conducted eye sensitivity adjustment training in the practical class of myopia prevention and control, and the heavy academic pressure caused students to use their eyes unscientific.
