According to the Ohio Lions Eye Research Foundation, a person with 20/600 vision sees something at 20 feet away that a person with typical 20/20 vision sees at 600 feet. In another comparison, a person sees an object at 2 feet that someone with perfect eyesight notices at 60 feet.
The American Foundation for the Blind states that 20/200 vision is the clinical definition for legal blindness. Therefore, a person with 20/600 vision is considered legally blind.
With 20/600 vision, an individual sees people only as shapes, WPTV indicates. CNN explains that this level of eyesight impairment is comparable to a newborn's eyesight.
