What is Legal Blindness?
Legal blindness refers to visual acuity of 20/200 or one-tenth of normal. This, however, does not mean that a person is completely unable to see things. This only means that your vision problem cannot be corrected with eye glasses or contact lenses any better than 20/200.
Who Has Legal Blindness?
Legal blindness simply means that what a person with healthy eyes can see from 200 feet away, a person considered to be legally blind can see only from 20 feet away.
A person is also said to be legally blind if he or she cannot see the line below the second big E at the top of the eye chart.
In the United States, about 1.1 million people are considered legally blind. Blindness is usually caused by various eye diseases such as cataracts, glaucoma, macular degeneration, and diabetic retinopathy.

The definition of legal blindness also helps legally blind people receive governmental benefits- from educational to monetary assistance.
