Research progress of prevention and treatment of myopia in teenagers by modern medicine

China is one of the countries with the highest incidence of myopia in the world, among which the prevalence of myopia in children and adolescents is increasing year by year, and the trend of younger age. Studies have shown that the younger the age of myopia, the more likely it is to develop into high myopia in adulthood. With the increase of myopia degree and the gradual extension of the eyeball, the probability of eye diseases (high myopia macular degeneration, open Angle glaucoma) also increases correspondingly, and refractory complications eventually lead to low vision and even blindness. If the current incidence of myopia can not be effectively prevented and controlled, it will become an important disease factor affecting the quality of life of the public in the future, and it will also become a problem for the prevention and control of eye diseases in the future. Therefore, preventing and controlling the formation of myopia in children and adolescents and (or) delaying the deepening of myopia degree is a common topic in the current research of traditional Chinese and Western medicine. The following is a summary of the relevant research on the prevention and control of children and adolescents in recent years in the modern medicine, hoping to provide references for the clinical prevention and control of myopia in children and adolescents, and provide possibilities for more in-depth, scientific and comprehensive prevention and control of myopia in adolescents in the future.
