Suggested Uses: Books, Newspapers, Magazines, and other Reading Material

A page magnifier can be a good choice for magnifying text or numbers. They come in a variety of sizes. The most common size is 8 inches x 10 inches (about the size of a standard sheet of paper). Smaller wallet sizes and bookmark sizes are also available. Before purchasing, please note the following:

First, this type of magnifier must be held about 3 to 4 inches above what you are trying to magnify in order to provide magnification. They will not provide any magnification when laid directly on top of your reading material. This is due to the optical properties of magnifiers and the size and shape of the page magnifier. If you are looking for something you can rest directly on top of your reading material, take a look at our dome magnifiers or bar magnifiers.

Secondly, unlike a traditional handheld magnifying glass, they are made with a Fresnel lens. A Fresnel lens provides magnification via a series of slightly raised concentric circles. This is one of the only ways to produce magnification on a thin, flat sheet, where the lens has no curvature. (With a traditional handheld magnifying glass, the curvature and thickness of the lens is directly related to the magnification power.) Fresnel lenses do not allow as much light to pass through the lens as a traditional (non-Fresnel) handheld magnifier allows. As a result, the clarity of a Fresnel lens magnifier is not as clear at that of a non-Fresnel lens magnifier.  FYI, Fresnel lenses get their name from their inventor, a French physicist by the name of Augustin-Jean Fresnel.

Finally, the magnification is limited to about 2x magnification power. This is attributable to their large, flat size and the use of the Fresnel lens.

Full page magnifiers are great for occasional use if you need just a little extra help seeing some small print, but they are not generally recommended for anyone with poor eyesight or a low vision condition such as macular degeneration, due to the limitations in clarity.

They can be made of a hard, rigid plastic such as the Carson Rigid Frame Magnifier. Or, a thin, flexible plastic sheet, such as the Carson MagniSheet.
