About

The study used children aged 6-18 as subjects to evaluate the efficacy and safety of naked eye 3D vision training for the prevention and control of myopia in adolescents. A total of 250 subjects were recruited from Zhongshan Ophthalmology Center of Sun Yat-sen University, Shenzhen People's Hospital and Foshan Women's and Children's Hospital, with 1:1 as intervention group and control group. The study assumes that daily naked eye 3D vision training can effectively control the speed of axial elongation and the progression of myopia. The main indicators were the use of optical biometrics to detect the subjects' initial axial length and the axial length after 1 month, 3 months and 6 months of intervention. Secondary indicators were refraction, uncorrected visual acuity, best corrected visual acuity, choroidal thickness, and binocular vision.
