There's no point in getting higher index lenses with a low prescription like that. You won't notice any difference in thickness, and the optical properties are better for the lower index (1.49) CR39 are better. Much less expensive, too.
"Index" is short for "index of refraction," not "index size." "Size" refers to the physical size of the parts of the eyeglasses. --~--~---------~--~----~------------~-------~--~----~ Check us out at the oft-updated http://glassyeyes.blogspot.com!
