Details and patient eligibility

About

The goal of this clinical trial is to evaluate the efficacy and safety of visual function training software (model: SJ-JRS2021) in the treatment of mild to moderate amblyopia in children. The main questions it aims to answer are:

Whether virtual reality training is more effective than occlusion therapy
Safety of virtual reality training in amblyopia treatment If participants have refractive problems, correct the refraction first and wear corrective glasses. The experimental group will be treated using visual function training therapy software (model: SJ-JRS2021). The control group will be treated with occlusion therapy covering the contralateral eye for 2 hours a day. Researchers will compare experimental group with control group to see if the experimental group has better corrected vision recovery.
