简要总结

Myopia is one of the major causes of low visual acuity during childhood. It is generally more prevalent in urban areas than in rural areas. Current evidence does not address our understanding of the myopia incidence and development and associated risk geographic factors, such as green spaces. Therefore, our study aimed to evaluate the association between geographic factors and myopia base on a population-based large-scaled cohort design.
