Legal blindness is defined in several ways. One is that a person has vision of 20/200 or less and it cannot be corrected. This means that this person sees at 20 feet what a normally sighted person can see at 200 feet away. Another way a person can have blindness is to not have a total "visual field". This means that a person cannot see the whole scene as a normally sighted person can. This is measured in degrees. A person with a visual field of less than 20 degrees is considered legally blind. Normally sighted people have a visual field of 180 degrees in a normal eye.
Blindness has many causes. In the United States, the leading causes are diabetes, glaucoma, macular degeneration, and accidents (such a chemical burns or sports injuries). Other causes of blindness include: blockec blood vessels, complications of premature birth, and complications of eye surgery.
The degrees of blindness vary. The totally blind have no light perception at all. Other individuals who have blindness may be able to distinguish between light and dark. Some may be able to tell the direction the light is coming from, while others may be able to distinguish hand motions.
Others can see but their field of vision is obstructed due to a visual impairment such as glaucoma or cataracts.
