Summary

This study tests two ways to prevent or slow myopia (short-sightedness) in children aged 7 to 10. One group gets special classroom lights that mimic sunlight, another group's parents get a smartphone app that encourages more outdoor time, and a third group gets standard care. Over one year, researchers will track how children's eyes change and also look at sleep and thinking skills.
