blindness. lack or loss of ability to see (see vision). Legally, blindness is defined as less than 20/200 vision in the better eye with glasses (vision of 20/200 is the ability to see at 20 feet only what the normal eye can see at 200 feet). A person with 20Â° or less vision (pinhole vision) is also legally blind.
Others assume it means the same thing as total blindness (complete lack of form and light perception). In fact, the terms legal blindness and legally blind mean neither of these things.
