Approximately 12 million people 40 years and over in the United States have vision impairment, including 1 million who are blind, 3 million who have vision impairment after correction, and 8 million who have vision impairment due to uncorrected refractive error.
What is the most common visual impairment?
The most common causes of visual impairment globally are uncorrected refractive errors (43%), cataracts (33%), and glaucoma (2%). Refractive errors include near-sightedness, far-sightedness, presbyopia, and astigmatism. Cataracts are the most common cause of blindness.
How common is visual impairment in children?
Vision impairment is not very common among children. More than half of children with vision impairment also have at least one other developmental disability, such as intellectual disabilities, cerebral palsy, hearing loss, or epilepsy. Vision impairment is more common in older people than in children.
