Students with uncorrected vision: an uncorrected problem
Can eyeglasses improve educational outcomes among children in poorer parts of the world? World Bank studies suggest that approximately 10% of all children in developing countries have problems with their eyesight. About 97% of child eye problems are caused by refraction errors, nearly all of which can be corrected with properly fitted eyeglasses. However, most children with refraction problems in low-income countries do not have glasses.
