What type of blindness is rare?

Stargardt disease is a rare genetic eye disease that happens when fatty material builds up on the macula — the small part of the retina needed for sharp, central vision. Vision loss usually starts in childhood — but some people with Stargardt disease don't start to lose their vision until they're adults.

What is considered legally blind?

Legal blindness occurs when a person has central visual acuity (vision that allows a person to see straight ahead of them) of 20/200 or less in his or her better eye with correction. With 20/200 visual acuity, a person can see at 20 feet, what a person with 20/20 vision sees at 200 feet.

There are a number of these degenerative diseases, including retinitis pigmentosa, macular degeneration and Usher syndrome.
