If you want to get inexpensive magnifier glasses which is also called reading glasses just to see whether you are comfortable with the diopter and don't need to fill the prescription, you can just go to the drug store to try them on. Buying them online is not as convenient as the real store. However, the reading glasses in the drug store is not very expensive.
