I need to buy a pair of prescription swim goggles, and it seems that the
places that sell them only sell lenses in ".5 diopter" increments. I
have a card with my prescription on it, that says:

OD -5.25 -75 x 090
OS -5.25 -25 x 090

I'm presuming the "-5.25" is my "diopter," which means I am in a
dilemma. Do I order -5.0 lenses, -5.5 lenses, or one of each (if the
"-75" etc. stuff is relevant)? Which is going to be better?
