Most of us have good vision, but 14 million are visually impaired
A National Institutes of Health (NIH) study found that although 94 percent of Americans aged 12 and older have good vision, the remaining six percent, or 14 million, are visually impaired.
Of these, more than 11 million have uncorrected visual impairment, such as nearsightedness. They need eyeglasses or contact lenses to improve their vision. Teenagers, people with diabetes, Hispanics, and people who are economically disadvantaged have higher rates of visual impairment and can most benefit from corrective lenses.
