Even when you go to Web sites for the aging, information on lighting is limited. This project will add to the information currently available. It will make people aware that they can improve their daily lives through lighting and teach them how to do it. As people age, their eyes change. Older people need more light to see well than younger people do.
Older people have a more limited ability to respond to changes in brightness.
They may also lose some sensitivity to color and have trouble discriminating between colors. In addition to these normal changes, aging eyes may develop cataracts, macular degeneration, or diabetic retinopathy. Changes in the visual system caused by age or visual impairment can interfere with an older person's ability to live independently. Good lighting, however, helps compensate for visual problems and supports more comfortable and effective performance of tasks. Unfortunately, people often have little knowledge of how to adjust the lighting within their homes for deteriorating vision.
