Abstract

An estimated 3 million people in the U.S. suffer severe visual impairments that cannot be corrected medically, surgically, or with conventional eyeglasses. People with this type of visual impairment are described as having "low vision", because in most cases the visual impairment can be attributed to reduced visual acuity. The most common complaints of people with low vision are the loss of reading, the inability to recognize faces and objects, and difficulty watching television.
