Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The primary objective of this study is to observe the change in the incidence and prevalence of myopia as well as the the progression of myopia among primary school students population under a school-based interventions, including increasing outdoor activities and wearing special designed optical lenses. The second objective is to identify factors influencing the outcomes and assess the compliance of different intervention methods. Additionally, a cost-effectiveness analysis will be conducted to assess the implementation process, providing technical solutions and operational models for wider application.
