A new study has found that spending as little as 15 minutes a day outside in bright sunlight could help prevent myopia in children.
The study was published on Aug. 13 in the Journal of the American Medical Association (JAMA). It was conducted as part of the Shanghai Time Outside to Reduce Myopia trial—a school-based cluster randomized clinical trial that followed school children in Shanghai for two years between October 2016 and December 2018.
