About

The study aimed to collect multi-factor information on school-age children with pre-clinical myopia, and to identify the initial factors and warning signs of myopia.

Full description

The incidence of myopia is high in China. At present, the mechanism of myopia is unclear, and the main theories are genetic and environmental aspects. Many factors may affect the occurrence and development of myopia in students, such as ocular biological parameters, peripheral refractive state, differences in binocular vision function, eye habits, and outdoor time. In this study, the multi-factor information on pre-clinical myopia in school-age children was collected to find out the initial factors and warning signals of myopia.
