A major feature of the Low Vision Public Education Program is a traveling exhibit. This exhibit will travel to various shopping malls around the country starting in 2000. "The traveling exhibit will help educate people with low vision on the services and visual aids that can help in maintaining independence and quality of life," Janiszewski said. "Visitors can use the multimedia touchscreen program and view a display of vision aids that can help a person with low vision perform routine tasks, such as reading or cooking. The exhibit will provide a resource list of local low vision agencies and organizations, and allow on-site volunteers from local organizations to answer questions."

Vision is the sensory modality that permits the individual to perceive the environment in terms of brightness, color, orientation, and depth. The organ for vision is the eye, where the retina consists of two sensory cells called cones and rods. Cones permit high visual acuity and color perception. Rods are suited for vision in low-light conditions. The rods and cones detect the light it receives from the environment and indirectly transduce the information to neural action potentials. The neural information is then transferred to the brain for processing in the visual cortex of the opposite side.

The exhibit, part of the NEI's Low Vision Education Program, is hosted by NEI grantee organizations and community groups. The exhibit, which made its debut in Birmingham, Alabama, in February, contains an interactive multimedia touch screen program; provides information on low vision materials and local services and resources; and displays aids and devices that help people with low vision live full lives. It includes five colorful kiosks and is designed to attract a cross-section of the population, from the young to senior citizens. Volunteers from the hosting organizations and groups staff the exhibit and help answer questions.

Vision is an essential part of everyday life, depended on constantly by people at all ages. Vision affects development, learning, communicating, working, health, and quality of life. In the United States, an estimated 80 million people have potentially blinding eye diseases, 3 million have low vision, 1.1 million people are legally blind, and 200,000 are more severely visually impaired.

Whether your visual impairment is mild or severe, low vision generally means that your vision does not meet your needs. Using visual devices to improve your vision usually begins after your ophthalmologist has completed medical or surgical treatment or determined that such treatments will not improve your vision.
