Refractive error myopia, hyperopia, astigmatism and amblyopia predominate in adolescent eye diseases, and a significant number of adolescents suffer from amblyopia. The incidence of myopia is much higher than other diseases among adolescent eye diseases. According to statistics, the prevalence of myopia among adolescents in China is as high as 60%-70%, increasing year by year, and the number of myopic eyes is the highest in the world. The prevalence of myopia among elementary school students is 30%-40%, 60%-70% for secondary school students, and up to 80% for college students. Female students are higher than male students; urban students have higher myopia than rural students.
