What Percentage of the Population Wears Glasses?
In the United States, approximately 64% of adults wear prescription eyeglasses. This equals about 166.5 million people. When you include contact lenses and reading glasses, the total number of adults using some form of vision correction rises to about 75% (roughly 197 million people). Globally, it is harder to get an exact number, but estimates suggest that at least 2.2 billion people have a vision impairment that requires correction.
