About this trial

This exploratory study investigates whether perceptual learning using blurred Gabor stimuli can improve uncorrected distance visual acuity in children aged 6-10 years with low myopia. Participants will be randomly assigned to a training group or control group. The training group will undergo individualized visual perceptual learning through a digital Vision Training System (VTS) for approximately 3 months. The study will also evaluate changes in refraction, contrast sensitivity, visual crowding, Chinese reading acuity with eye movements, and sweep visual evoked potentials (sVEPs).
