subject: magnifying glass [print this page] For the most convenience in magnification, you may want to consider a pair of quality reading glasses for your hobbies and other visual demands. Readers are essentially a pair of magnifiers built into an eyeglass frame. They range in powers from +1.00 to +3.00 diopters. +3.00 being the strongest. Because they remain close to the eye, rather than close to the object, such as a regular magnifying glass the power is depicted in fixed diopters rather than "x" amount of magnification.
