Definition - What does Legally Blind mean?
"Legally blind" is a status for visually impaired persons whose sight problems cannot be fixed by normal means such as through wearing corrective lenses.
To be considered legally blind, the person has to have vision of less than 20/200 (6/60), or have less than 10% field vision.
Justipedia explains Legally Blind
A person can have legal blindness from something that is genetic, i.e. they could have been born with it, or it could be a side effect of another disability or illness such as autism or cerebral palsy, or through blunt force trauma from a car accident.
People that are considered legally blind in the United States are allowed to collect full disability social security payments, and are not expected to enter the workforce, unless by choice. The act of not being able to improve the sight to a higher degree is what entitles a person to use the disability status.
Once a person is legally blind, the person usually remains so throughout their lives. People who are legally blind often have a caregiver part or full-time, which is paid for through medical aid, i.e. part of their social security benefits that the person would be entitled to.
Legally blind people are strictly forbidden from driving.
