Exclusion criteria
Exclusion criteria: 1.Known systemic or ocular diseases that may affect vision or refraction (including infections). 2. Systemic diseases affecting ocular health (e.g., diabetes mellitus, Graves' disease, ankylosing spondylitis, multiple sclerosis, Sjögren's syndrome, systemic lupus erythematosus). 3.Use of systemic or topical medications known to alter ocular status/affect ocular health during the study period. 4.History of ocular trauma. 5.Amblyopia. 6.Manifest strabismus. 7.
