What Eye Prescription Is Legally Blind?

Answer

A person is considered legally blind when his or her best corrected vision with conventional prescription glasses or contact lenses in the best eye results in a visual acuity no better than the top 20/200 line on the eye chart. That means the patient can read no more than the big E at a distance of 20 feet. A person can also be considered legally blind when the field of vision is narrowed to 20 degrees or less which is called tunnel vision.
