Epidemiology and Demographics

In 1987, it was estimated that 598,000 people in the United States met the legal definition of blindness[1]. Of this number, 58% were over the age of 65[1]. In 1994-1995, 1.3 million Americans reported legal blindness[2].

In November 2004 article Magnitude and causes of visual impairment, the WHO estimated that in 2002 there were 161 million (about 2.6% of the world population) visually impaired people in the world, of whom 124 million (about 2%) had low vision and 37 million (about 0.6%) were blind. [3]
