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).

Blindness is the inability to see anything, even light. If youâre partially blind, you have limited vision. For example, you may have blurry vision or the inability to distinguish the shapes of objects. Complete blindness means that you canât see at all and are in total darkness. Legal blindness refers to vision thatâs highly compromised. What a person with healthy eyes can see from 200 feet away a legally blind person can see only from 20 feet away.
