Let me clarify what we mean by visual impairment. Not everyone is totally blind. Visual impairment is a functional limitation in seeing, even with glasses and best correction of vision that is possible. Legal blindness is defined by law to determine eligibility for services. Someone who has 20/200 or less vision in the better eye with best possible correction is legally blind. Also, a person with severely restricted visual fields, less then 20 degrees, is legally blind. Just in case you don’t understand those numbers, let me explain a little more. A simplified explanation is that, roughly, someone with 20/200 vision sees at 20 feet what someone with “normal vision” (20/20) sees from a distance of 200 feet. Visual field restriction of 20 degrees or less means someone sees through a narrowed area of vision, sometimes called tunnel vision.
