Other related information

The patients were classified into a Glasses treatment group (treated with only glasses) and the Occlu-pad treatment group (treated with glasses in combination with the Occlu-pad).By analyzing visual acuity at 3 months and 6 months after amblyopia training begins, verify the amblyopia training effect of Occlu-pad.
