What this trial studies

This observational study aims to assess the prevalence and progression of myopia among school-aged children and adolescents in Tianjin, China, while examining the influence of socio-economic and environmental factors. Researchers will collect data on various parameters, including medical resources and school-related environments, to understand their impact on myopia development. The study will involve long-term observation of participants aged 6 to 18 years who consent to eye examinations, providing valuable insights into this growing public health issue.
