Eligibility
Inclusion criteria
Inclusion criteria: 1. Children aged 7 to 12 (including the cut-off value); 2. Computerized optometry after cycloplegia: -6.00D = 1.0 (0.0logMAR; Snellen20/20); 5. Anisometropia (equivalent spherical lens aberration) of both eyes < 1.00D; 6. The eye examination was normal and the intraocular pressure was normal.
Exclusion criteria
Exclusion criteria: 1. Possibly suffering from eye diseases that affect vision or refractive error (such as keratopathy, cataract, glaucoma, macular degeneration, etc.); 2. There is anisometropia (the difference between the equivalent spherical lenses of the two eyes) >= 1.00D, strabismus, and amblyopia; 3. Any pathological change of the eyeball or systemic disease; 4. Halo patients, cured tics, cured ADHD, psoriasis patients; 5. Those who have used myopia control treatment methods within 3 months, such as atropine, orthokeratology lenses, multifocal soft lenses, multifocal hard lenses, and functional glasses; 6. Other reasons that the research doctor thinks are not suitable for inclusion in the project.
