A page magnifier can be a good choice for magnifying text or numbers. The large size of a page magnifier enables one to magnify a large section of text at one time.
Full page magnifiers are usually about 8 inches x 10 inches in size and are made to magnify an entire page of text at a time. Before purchasing a full page magnifier, please note the following:
First, a full page magnifier must be held about 3 to 4 inches above the page in order to magnify the page. They will not provide any magnification when laid directly on a page. This is due to the optical properties of magnifiers and the size and shape of the full 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, a full page magnifier is 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 like a page magnifier. (Traditional handheld magnifiers do not use Fresnel lenses because they produce magnification in part because of the curvature of the lens. Flat sheets like page magnifiers have no curvature. Therefore a Fresnel lens is used to provide magnification.) The bottom line here is that the clarity of a Fresnel lens magnifier is not as clear at that of a non-Fresnel lens magnifier. Fresnel lenses do not allow as much light to pass through the lens as a traditional (non-Fresnel) handheld magnifier allows. FYI, Fresnel lenses get their name from their inventor, a French physicist by the name of Augustin-Jean Fresnel.
Finally, the magnification of a full page magnifier is limited to about 2x magnification power. This is attributable to their large size.
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.
