Abstract: according to statistics, more than half of the world’s 7 billion people have visual impairment. In China’s 1.3 billion population, the incidence of myopia is as high as 25%. Among them, teenagers are mostly myopic, and about 70-80% of students in middle schools are myopic., Experts say that genetic factors play an important role in the occurrence and development of myopia. If one of the husband and wife is myopic, the probability of children’s myopia is about 50%; Both husband and wife are nearsighted, and the probability of children’s nearsightedness is as high as 85%. From the perspective of eugenics, ophthalmologists do not recommend that men and women with high myopia marry and have children., Statistics show that more than half of the world’s 7 billion people have visual impairment.

Therefore, myopia is called “national disease”, which seriously affects China’s population quality and national security., How to effectively prevent and control the occurrence and development of myopia.
