Diopter Defined: a "diopter" is a term that refers to magnification power of a device and is the unit of measure used by eye doctors. While magnifiers are frequently referred to in "X" powers, this definition can vary across manufacturers. Diopter, however, does not vary and is a consistent measurement.

Biconvex Defined: Convex is curving out. This particular lens on this magnifier is biconvex which means that it curves outward on both sides.
