Electronic Magnifiers

Electronic magnifiers, also called video magnifiers or CCTV magnifiers, use a camera and a screen instead of a glass lens. They reach magnification levels no optical magnifier can match, and they let you change colour and contrast to suit your eyes. For advanced low vision, they are often the tool that keeps reading possible.

How electronic magnifiers work

A built-in camera captures the page and displays it enlarged on a screen. Because the magnification is digital, you can zoom far beyond what a glass lens allows, often up to 20x or more on handheld units and much higher on desktop models. You can also freeze an image to study it.

Handheld electronic magnifiers

Pocket and handheld units have a small screen, usually 3.5 to 5 inches, and a camera on the back. You hold them over the text and read from the screen. Portable, battery powered, good for menus, labels, price tags, and mail when out and about.

Desktop and CCTV magnifiers

Desktop units have a large screen and a camera mounted above a sliding tray. You place a book or document on the tray and read at high magnification with both hands free. These suit long reading, letter writing, and hobby work for people with significant sight loss.

Contrast and colour modes

The big advantage over a glass magnifier is contrast control. Most electronic magnifiers let you switch to high-contrast modes such as white-on-black, yellow-on-blue, or boosted colour. For many low-vision conditions, the right contrast mode matters as much as the magnification.

Who electronic magnifiers suit

They suit moderate to advanced low vision, especially macular degeneration, where a normal magnifier no longer gives enough enlargement or contrast. If a strong optical magnifier has stopped being enough, an electronic magnifier is the logical next step. Your optometrist or low-vision clinic can advise on magnification and screen size.
