School-based Myopia Prevention Trial for Children With Adequate Hyperopic Reserve
Sponsor: Shanghai Eye Disease Prevention and Treatment Center
Summary
This is a prospective, school-based randomized controlled trial designed to evaluate a wearable device-supported outdoor activity program for myopia prevention in primary school students with adequate hyperopic reserve. Enrolled students in grades 1 to 4 will be randomly assigned to either a wearable device-supported outdoor activity program plus routine school-based eye health education or routine school-based eye health education alone. Outcomes will include changes in axial length and cycloplegic spherical equivalent refraction, incident myopia, intervention adherence, and safety outcomes over 12 months.

Conditions
Interventions
Wearable Device-Supported Myopia Prevention Program
The wearable device-supported program will use smart wearable wristbands to monitor outdoor activity time and provide reminders. Students in the intervention group will be encouraged to increase outdoor activity, with targets of at least 1 hour per day on school days and at least 2 hours per day on weekends. Data recorded by the wearable device will be used to quantify daily outdoor activity and assess adherence to the intervention.
Eye Health Education
Routine school-based eye health education will include general guidance on healthy visual behaviors, including reducing prolonged near work, maintaining appropriate reading posture and lighting conditions, performing standard eye exercises, and undergoing regular eye examinations.
