Common Vision Disorders in Children

According to a 1991-1994 CDC study of metropolitan Atlanta area children, approximately 9 in every 10,000 children ages 3 to 10 have low vision or blindness. Two thirds of the children had other disabilities besides having vision impairment. The World Health Organization defines low vision as a visual acuity of 20/70 to 20/400 with the best possible correction.
