This study focuses on the impact of outdoor sports design on preschool children’s vision. A model kindergarten in downtown Shanghai was selected to investigate children’s eye habits and parents’myopia. The factors affecting children’s visual acuity were analyzed by single factor analysis. Parents’myopia was the main cause of vision problems in early childhood(P＜0.001). Some outdoor exercise games were designed based on the eye muscle regulation mechanism to help improve children’s visual acuity, and were implemented in different age groups. The Snellen acuity chart examination and computer optometry refractive data were comprehensively analyzed. After the implementation of the exercise game, there was a significant difference in visual acuity between the two groups(P=0.012), and it was found that the effect was most obvious for children with potential visual risks, especially for middle and older children. This kind of sports game has a positive role, which is suitable for popularization in kindergartens and families.
