Inclusion criteria
Inclusion criteria: 1. Age 6 to 12 years, any gender; 2. Refractive status meets the following conditions: (1) After cycloplegia, computer-based refraction shows both eyes with an equivalent spherical diopter between -0.50D and -6.00D (including -0.50D and -6.00D); (2) After cycloplegia, computer-based refraction shows astigmatism in both eyes not exceeding 2.0D; (3) After cycloplegia, computer-based refraction shows anisometropia in both eyes less than 2.00D; 3. Intraocular pressure in both eyes is normal (greater than or equal to 10 mmHg, less than or equal to 21 mmHg); 4. Best-corrected distance visual acuity in either eye is equal to or better than 0.8; 5. No amblyopia or any other pathological changes in either eye; 6. The patient fully understands and voluntarily participates in this study, and the informed consent form is signed by both the patient and the parent/guardian.
Exclusion criteria
Exclusion criteria: 1. Any ocular or systemic diseases that may be related to the development of myopia or affect refractive status (such as congenital cataract, retinopathy of prematurity, Marfan syndrome, diabetes, etc.); 2. Presence of manifest strabismus or obvious binocular visual function abnormalities; 3. Unwillingness to cooperate with visits; 4. Other situations where the researcher determines the patient is not suitable for inclusion; 5. Currently participating in other clinical trials that may affect this study, or having used other myopia control methods within the past three months, such as low-concentration atropine, orthokeratology lenses, red light therapy, etc.
