Brief Summary
Refractive errors constitute the leading cause of visual disability worldwide and that myopia progresses dramatically when students reach school age. Studies from different countries have reported inconsistent associations between educational outcomes and refractive errors. Therefore, our study aimed to assess the associations of high academic performance with ametropia prevalence and myopia progression in Chinese schoolchildren base on a multicohort observational design.
