Expanding possibilities for people with vision loss

CCTV/Video Magnifier

Video magnifiers (also known as closed circuit television systems or CCTVs) are some of the more sophisticated and powerful magnifying tools available to workers with low vision. They may be necessary for some tasks when a hand-held or stand magnifier (a prescribed optical device) will not work; however, not all employees with vision loss will need these products. There are many video magnifiers made by several manufactures commercially available. For a full list of available video magnifiers and where to purchase them, visit AFB's Product Database.

Video magnifiers consist of a video camera connected to some type of monitor such as a computer monitor.

  1. Materials can be placed under the camera and an enlarged image of the material is displayed on the monitor.
  2. The user adjusts a zoom lens to enlarge the image to the desired size.
  3. Other features such as color, dark text on a light background or light text on a dark background, and auto-focusing enhance the user's efficiency when performing literacy tasks.
