What is low vision? What does it mean to be partially sighted?
Low vision is a significant reduction of visual function that cannot be corrected to the normal range by ordinary glasses, contact lenses, medical treatment and/or surgery. People are considered partially sighted if their best-corrected visual acuity is 20/70 or less in their good eye. Even when wearing regular corrective lenses, partially sighted people cannot read standard newsprint, or see expressions on a person’s face. There are approximately 4.3 million Americans who have been diagnosed as partially sighted. An estimated 8-10 million more Americans report vision problems that interfere with their ability to perform daily activities without help.
