Blindness avoided for millions of children

The major causes of childhood blindness are congenital cataract; uncorrected refractive errors, such as near-sightedness, far-sightedness or astigmatism; retinopathy of prematurity (a disease of some premature babies); vitamin A deficiency (xerophthalmia); tumors; and glaucoma. Most of these conditions are treatable and, when detected and cured, can help to ensure fruitful lives for millions of children.
