Answer :
Students are considered legally blind when the visual acuity in their better eye is 20/200, which is much weaker than normal vision.
Students are considered legally blind when visual acuity in the better eye is 20/200. This means that what they can see at 20 feet, a person with normal vision could see at 200 feet. Legal blindness also includes cases where the person’s visual field is 20 degrees or narrower.
Visual impairment ranges from low vision to total blindness, with low vision defined as having visual acuity worse than 20/60, but not as severe as legal blindness. Health professionals and educators make adaptations to support students with visual impairments, including those that are legally blind. Awareness of these conditions is vital to addressing them effectively, especially given the expected increase in the population with visual impairments due to aging demographics. Hence, option d. 20/200 is the correct answer.
