Exclusion criteria
Exclusion criteria: 1. Myopic patients; 2. Subjects with a history of intraocular surgery, refractive surgery, or a combination of organic eye disease related to vision loss, or, according to the investigator's judgment, any other potential reasons that may lead to a decrease in BCVA; 3. Treatment history of low compliance with amblyopia treatment informally assessed by the investigator; 4. History of light-induced epilepsy; Wear rigid breathable contact lenses; Any reported ocular anatomical abnormalities (for example, partial opacity of the lens, myelinated nerve fibers, etc.); 5. Subjects' participation in other clinical studies within 3 months; 6. The presence of other conditions such as subjects not wearing glasses and not being able to cooperate in completing the test, as assessed by the investigator; 7. Any situation that may prevent the subject from completing the daily continuous 20-60 minutes of training in front of the close-up monitor. For example, the subject is unable to pass the Vision Planet suitability test-own or with guidance from others; 8. Always see strabismus with near eye deviation >= 10? (measured by PACT). 9. Subjects had paracentric gaze.
