Eligibility criteria
Inclusion Criteria: 1. Child (female or male) aged 6 to 12 years. 2. Myopia (SER of at least -0.50 D and no more myopic than -6.00 D) in each eye as measuredby cycloplegic autorefraction. 3. If present, astigmatism of ≤1.50 D in each eye as measured by cycloplegic autorefraction. 4. Anisometropia SER of \< 1.50 D as measured by cycloplegic autorefraction. Exclusion Criteria: 1. Have used other myopia control methods other than those used in this study, such as instruments (orthokeratology lenses, multifocal glasses, progressive glasses), drugs (atropine, etc.); Only single vision glasses are allowed for myopia correction; 2. Have used myopic control methods such as traditional Chinese medicine, auricular acupuncture, massage, and reverse beat within 30 days before screening; 3. Use of any local or systemic antimuscarinic/anticholinergic medication (e.g., atropine, scopolamine, tropicamide, phenamine, diphenhydramine, oxytropine, tricyclic antidepressant, etc.) within 21 days before screening; Allowing for tests such as cycloplegic optometry;
