What is 1.00 in reading glasses?

They are "diopters," and act as a measurement of the magnification level in the lens. A lower number means less magnification, and as you go up, the magnification gets stronger and stronger. You'll typically see glasses that start with a diopter level of around +1.00 and go up to +3.00.
