At what percentage do you become a registered blind person?

20/200: In most states, the break point is 20/200 which is the next line below the big e on most charts. This allows, if present in both eyes, to be able to receive a number of charitable benefits and tax benefits as well.

Reduced vision : Legal blindness in most states is 20/200 or worse in the better eye. Most states also have a minimal peripheral visual field (side vision) requirement of 20 degrees or less in the better eye.
