Video magnifier icon

Video magnifiers are electronic devices that use a camera and a display screen screen to perform digital magnification of printed materials. The display screen is usually LCD or a similar flat-screen technology (although older video magnifiers have used CRT displays), and the device usually includes a lamp to illuminate the source material. Video magnifiers are designed to be mostly used by people with vision that can no longer be helped using a conventional magnifying glass.
