A visual impairment is defined as an impairment of sight which cannot be adequately corrected with pharmaceutical or surgical interventions, conventional prescription eyewear, or contact lenses. The individual may have a loss of visual acuity, loss of visual field, increased light sensitivity, distortion, loss of color vision, or loss of contrast. This creates difficulty with reading, writing, watching TV, and performing activities of daily living which leads to a loss of independence.
