The prevalence of myopia is increasing—particularly in Asia. Several studies suggest that increased time spent outdoors may protect against the development of myopia or slow its progression. He and colleagues assessed the relationship between increased time outdoors and myopia development in a cluster randomized trial involving 1903 primary school children (mean age, 6.6 years) in Guangzhou, China. During the 3-year trial, children at 6 intervention schools participated in an additional 40-minute class of outdoor activities each school day, and children at 6 control schools continued their usual activity. The authors report that among the 6-year-old study participants, additional outdoor activity daily at school reduced the incidence of myopia over the 3-year study period. In an Editorial, Repka discusses current challenges in myopia prevention and progression.
