How many blind people are in the world?
The WHO estimates that in 2002 there were 161 million visually impaired people in the world (about 2.6% of the total population). Of this number 124 million (about 2%) had low vision and 37 million (about 0.6%) were blind. In order of frequency the leading causes were cataract, uncorrected refractive errors (near sighted, far sighted, or an astigmatism), glaucoma, and age-related macular degeneration.
