One very important point to remember is that even when the legally blind person is 20 feet away from the object, others with unimpaired vision cannot assume that this person can see all the details that they are able to see.
Additionally, a person with normal vision has a total visual field of 180 degrees for peripheral vision while someone who is legally blind only has the ability to see objects that are located within a 20 degrees visual field.
