![]() The Social Security Administration of the United States declares a taxpayer disabled for economic purposes and eligible for supplemental security income when the best corrected visual acuity is 20/200 or worse in the better eye, the visual field is limited to 20 degrees or less in the better eye, or both. Blindness is defined as visual acuity of less than 20/400 or corresponding visual field loss to less than 10 degrees in the better eye with the best possible correction. Low vision is defined as visual acuity between 20/60 and 20/200 or corresponding visual field loss to less than 20 degrees in the better eye with best possible correction. The World Health Organization lists several categories of visual disability. Individual states and the District of Columbia have their own vision requirements for initial and renewal licensing. While there are strict federal vision standards for commercial licensing, there are no such international standards, and there are no federal standards for unrestricted noncommercial passenger vehicle drivers’ licenses in the United States. ![]()
