reading glasses, .50 strength, how to search?

Searching for [reading glasses .50] gets me 2.50, etc., on both Google and Amazon. ReadingGlasses.com has expensive ones, but I'm hoping to find good, low-strength reading glasses for the same price one would pay in a drug store. Strength .5 and/or .25. Any specific recommendations or search tips? (and what is the unit of measurement, anyway?)
