• How bad can your eye prescription be if you are legally blind?

  Legally blind has nothing to do with the prescription numbers. Legally blind means that your best vision cannot be corrected with glasses or contact lenses any better than 20/200. A normal person with 20/20 vision can see objects clearly that is 200 feet away from him, while the legally blind person can only see the object clearly that is 20 feet away from him. A legally blind person can't see objects clearly that is very far or close.
