Eligibility
Inclusion criteria
Inclusion criteria: 1. Aged 6 to 12 years, regardless of gender. 2. Ability to provide informed consent, signed by a parent or legal guardian who understands and accompanies the participant. 3. Spherical equivalent refraction under cycloplegia = -0.50 diopters (D) and > -3.00 D in both eyes; anisometropia and astigmatism = 1.50 D; best-corrected visual acuity (BCVA) of 0.8 or better in both eyes. 4. Willingness to wear exclusively the spectacles provided by the investigator for more than 10 hours per day throughout the study period, with no additional myopia control interventions.
Exclusion criteria
Exclusion criteria: 1. Known allergy or intolerance to cycloplegic agents. 2. Use of any myopia control intervention within the past 3 months, including but not limited to: atropine, orthokeratology (OK) lenses, defocus spectacle lenses/multifocal soft contact lenses, or red light therapy. 3. Diagnosis of any ocular condition other than myopia in either eye, including but not limited to: manifest strabismus, corneal disease, conjunctival or eyelid injury, or other disorders (e.g., keratoconus, herpes simplex keratitis); history of ocular surgery (including strabismus surgery); any ocular or systemic disease that may be associated with myopia or its progression, such as Marfan syndrome, retinopathy of prematurity, diabetes mellitus, etc. 4. Any other condition which, in the opinion of the investigator, would make the participant unsuitable for inclusion in the study.
