According to the Social Security Administration, 20/80 visual acuity is not “poor” enough for a patient to be legally blind. According to the Emory Eye Center, patients with 20/80 vision may need eyeglasses or contact lenses to help with the visual acuity needed to perform fundamental tasks like writing a check or reading the newspaper.
A person with statutory blindness has a corrected vision of 20/200 or less, according to the Social Security Act. Because the Snellen acuity chart, also known as the eye chart with the giant “E” at the top, contains no lines between 20/100 and 20/200, anyone who cannot recognise any letters on the 20/100 line is classified as statutorily blind by Social Security.
Patients with 20/80 vision may see objects from a distance of 20 feet that those with normal or 20/20 vision can see from a distance of 80 feet. The Snellen acuity chart evaluates a patient’s visual acuity but does not identify the cause of his vision problems. According to Ophthalmic Technician, doctors collaborate with patients to make this discovery and make the necessary repairs.
According to the American Medical Society, to drive an automobile, one must have vision corrected to at least 20/40 in the better eye in all but three states. Drivers who need corrective glasses to achieve these requirements have their licences restricted. Commercial drivers are subject to even stringent federal regulations than non-commercial drivers.
