Low Vision

The term "low vision" (or "partial sight.") usually indicates vision of less than 20/200.

The 10th Revision of the WHO International Statistical Classification of Diseases, Injuries and Causes of Death defines low vision as visual acuity of less than 6/18, but equal to or better than 3/60, or corresponding visual field loss to less than 20 degrees, in the better eye with best possible correction.
