Study of the Intervention Effect of Outdoor Activity Period Patterns in Promoting Myopia Among Preschool Children
Sponsor: Fangbiao Tao
Summary
This study is a randomized controlled trial based on outdoor activity interventions at specific time periods, involving preschool children aged 4 to 5 years. It compared the axial length and myopia incidence between the intervention group and the control group at the 6th and 12th months of the intervention to determine the effect of outdoor activities at specific time periods on the prevention of myopia in preschool children. Additionally, the study investigated the association between outdoor activities at specific time periods and axial length and myopia in preschool children.
