Inclusion criteria
Inclusion criteria: 1. Age between 6 and 14 years old (inclusive of 6 and 14 years old). 2. Under cycloplegia, the equivalent spherical refractive power range of subjective refraction for both eyes is -0.75D to -6.00D (including -0.75D and -6.00D), and the astigmatism value of subjective refraction for both eyes is less than or equal to 2.00D. 3. Anisometropia of both eyes is less than 1.50D. 4. Best corrected visual acuity (BVCA) is greater than or equal to 1.0. 5. Parents/guardians and children sign the informed consent form.
Exclusion criteria
Exclusion criteria: 1. Any ocular or systemic diseases that may affect visual function or refractive development. For instance, strabismus, cataract, glaucoma, etc. 2. Previous history of ocular trauma and surgery. 3. Previous experience with other treatments for myopia control.
