There are even blind people who use a form of echolocation Legal blindness, however, is not the same thing It simply means that you are unable to see any better than the /0 line on the eye chart when best corrected If you can see at feet what someone with / vision sees 0 feet away, you might be considered legally blind A person with /50 vision is considered to have visual impairment, according to WebMD Individuals with /50 visual acuity can see an object clearly at feet away that individuals with normal vision can see clearly at 50 feet away Those with / visual acuity are defined as having normal vision, according to All About Vision/0 This is the level at which you are considered to be legally blind That means a person with /0 vision has to be feet away from an object to see clearly, whereas a person with normal eyesight can see clearly at 0 feet away We'd like to make a special note that having / vision does NOT mean that you have perfect eyesight
