The devices listed in this reference circular are designed to assist people who have visual impairments by magnifying objects and print or graphic materials. Before buying a magnification device, one should consult a low-vision specialist to determine the level of usable vision, the power of magnification needed for a particular eye condition and particular task, and to learn how to use the magnifier correctly. A student has different visual needs than a working-age adult or an older adult who may be retired. The first two sections list available products and the third section gives the addresses and telephone numbers of the producers and vendors. Subsequent sections provide a selective list of books and journal articles related to low vision, describe evaluations of specific devices, and list selective Internet resources. Because prices are subject to change without notice, contact companies directly to verify current prices and product specifications. Visit the web site of companies to check for the availability of Internet specials, free demonstration software, and home trials. Items listed in this reference circular are not part of the National Library Service for the Blind and Physically Handicapped program, and their listing does not imply endorsement. (AEF)
