A method for providing a plurality of pairs of reading or computer glasses comprising the steps of:

• providing at least a first pair of eyeglasses that has a first lens and a second lens, wherein the first lens and second lens have a first optical center and a second optical center, respectively, that are spaced at a first optical center distance (OCD);
• providing at least a second pair of eyeglasses that has a third lens and a fourth lens, wherein the third lens and fourth lens have a third optical center and a fourth optical center, respectively, that are spaced at a second optical center distance (OCD), thereby providing at least two optical center distances (OCDs);
• and providing said glasses for sale on an over the counter (OTC) retail non-prescription basis, wherein the at least two OCDs are based upon a specific viewing distance or range of viewing distances, and further based upon a prevalence of near pupillary distances (NPDs) and their respective weighted means and standard deviations among a specified gender and race or a specified mix of genders and races of a population.
