Legal Blindness

Legal blindness is a baseline measurement of vision loss that qualifies for benefits. Most government agencies and healthcare institutions agree it refers to a central visual acuity of 20/200 or less in the better eye with the best possible correction, and/or a visual field of 20 degrees or less.
Legal blindness always requires both eyes meet the minimum measurement; there is no such thing as “legal blindness in one eye.”
Legal blindness should not be confused with “blindness” which is generally understood to mean an inability to differentiate light from dark or see at all. Most people who qualify for legal blindness have varying degrees of usable vision.
