What does it mean to be blind or visually impaired?
What does it mean to be blind or visually impaired?
When you hear the term “blind,” you likely think of someone who has no vision at all. But that’s just one part of the visual spectrum. Here are some other terms you should know.
Partially sighted: A person who is partially sighted has some vision in one or both eyes. This term is frequently used in educational settings.
Low vision: This term describes a person with poor vision that cannot be fully corrected with glasses or contacts. In some cases, the person can see things up close but not at a distance, or vice versa. Others have poor visual acuity across the entire spectrum.
Legally blind: A legally blind person has vision that cannot be corrected to better than 20/200 in at least one eye. It also refers to those who have a field of sight of 20 degrees or less.
Totally blind: One who is blind has total loss of sight.
Students may fall anywhere along this spectrum, so it’s important to know more about their specific level of impairment. They may have an IEP or 504 on file, so study it carefully to learn what you can do to help them do well in your classroom.
