Brief Summary

The prevalence of myopia among high school students in China is as high as 80%-90%. For college students with longer years of education, the majority of myopia and the factors influencing the prevalence of high myopia should be better understood for timely prevention and treatment. This study aims to investigate the prevalence of myopia and education-related influencing factors among college students at Nankai University.
