Inclusion criteria

Inclusion criteria: 1. Age 8-12 years old (inclusive), gender is not limited; 2. At the time of screening, the equivalent spherical power (SE) of both eyes was -0.50D~-6.00D (computer automatic refraction after ciliary muscle paralysis); binocular columnoscopy <=1.50D; Anisometric refraction in both eyes (according to the equivalent spherical power) <=1.50D; 3. Intraocular pressure in both eyes is <=21mmHg; 4. Best corrected distance visual acuity in any eye at least 5.0 logarithmic visual acuity at screening; 5. Subjects voluntarily participate in the clinical study and obtain written informed consent signed by the legal guardian and the child.

Exclusion criteria

Exclusion criteria: 1. Current or past history of overt strabismus (including intermittent strabismus) and amblyopia in any eye; 2. Confirmed pathological myopia; 3. Abnormal refractive media of any eye (e.g., keratoconus, conical lens, spherical lens, etc.); 4. Other congenital eye diseases; 5. Participation in other clinical trials within 30 days before screening; or are using atropine, OK lenses, or any other treatment to control myopia; 6. Regular use of eye medications and artificial tears; 7. Only one eye meets the selection criteria; 8. Severe systemic diseases, which the investigator considers unsuitable for participation in this study; 9. Poor compliance, unable to go to medical institutions in time and regularly as required; 10. Other reasons that the study doctor deems unsuitable for inclusion, etc.
