The last time I got reading glasses the Dr. was kind enough to tell me what my prescription was. She recommended I go to the drug store and pick up some of those cheap reading glasses they sell in different strengths. I got some great multicolored ones that remind me of confetti. I know it wouldn't work for a more complicated prescription, but maybe something would get you by just for reading. It sucks to have to search the house for a magnifying glass. (I have first hand experience at this.)
