Eligibility
Inclusion criteria
Inclusion criteria: 1.Age: 5-10 years; 2.Spherical equivalent refraction (SER) between +0.75 D (inclusive) and -0.50 D (exclusive) in either eye after cycloplegia, with astigmatism =2 axial length measurements during pre-baseline observation (>=3-month interval), demonstrating annualized axial elongation rate >=0.3 mm/year; 4.Uncorrected distance visual acuity (UDVA) >=4.9 (Snellen) in either eye; 5.Absence of manifest strabismus at distance/near with cover test; 6.Expected completion of >=12-month follow-up OR availability of complete annual visit data (refraction & axial length); Prospective section: 1. Recruit children who meet the above inclusion criteria in the outpatient clinic in real time; 2. After signing informed consent, conduct regular follow-ups and collect refractive and axial length data according to a standardized process.
Exclusion criteria
Exclusion criteria: 1.History of any myopia control intervention (e.g., low-dose atropine, low-intensity red-light therapy); 2.Systemic/physical conditions preventing stable spectacle wear; 3.Psychological/psychiatric disorders posing harm risks during spectacle wear; 4.Inability to adhere to study protocols for reliable measurements; 5.Active ocular diseases affecting refractive development (e.g., retinopathy, cataract, ptosis); 6.Systemic/neurodevelopmental conditions impacting refractive development Concurrent ocular/systemic medications affecting retinal modulation, IOP, or myopia progression;
