Does modern technology help visually impaired people?
Magnification, contrast and lighting can help maximize a person’s remaining sight. New technology allows a person to control the size of the print they are reading, to adjust the contrast and color, and increase the brightness. For example, the closed circuit television (CCTV) allows the user to project any document or picture on to a screen and to magnify the document and adjust the contrast. Hand-held scanners and head-mounted devices perform a similar function as the CCTV, but use small cameras to place an image in front of your eyes or on a portable LCD screen. Large print and screen reading programs for computers are a tremendous resource. Advances in lighting technology have helped, as well.
