Refractive Errors Clinical Trial
Official title:
Prevalence of Refractive Errors in Primary School Children in The New Valley
The study aim to determine the prevalence of refractive errors in primary school children aged 6-12 in The New Valley , Egypt .
The refractive state of the eye changes as the eye's axial length increases and the cornea and lens flattens. In general, eyes are hyperopic at birth, and become slightly more hyperopic until the age of 7, at this point we see a myopic shift toward Plano until the eyes reach their adult dimensions, usually by about the age of 16. ;
