reading glasses diopter strengths are explained in detail ... The optical power of a lens with a focal length of 1 meter (about 39 inches) is said to be 1 diopter. Because the formula is based on the reciprocal of the focal length, a 2 diopter lens is not 2 meters but 1/2 meter, a 3 diopter lens is 1/3 meter and so forth.

Below is an example of how two power ratings can be achieved for the same 8 diopter lens. Formula A: diopters/4=power ; 8/4=2X; Formula B: diopters/4 + 1 = power; 8/4 + 1 = 3X; The question is, "Does an 8-diopter lens make an object look 2 times bigger or 3 times bigger?";

So, if a one diopter lens brings parallel rays to a point at one meter, the lens that has a focal length of two meters bends the rays LESS and the lens that brings the rays to a point at 1/2 meter bends the rays MORE.

This patent pending diopter formula delivers a very sharp red image. Tests indicate the improvement to range from 3 to 7 times better acuity! And slight added power in both lenses makes viewing easier at computer distances.
