If you don't have space for a microscope, you can also get yourself the long-range (~400mm) 2.5-3.5x magnifiers that you may have seen your dentist wear. They're easily available on Amazon, not too expensive, and comfortable for hours of wearing. These are 2-element lenses that work really well.

Higher magnification variants (8x etc) are not nearly as comfy. They get quite long, heavy and expensive. I tried them and did not like them nearly as much. Also beware of short viewing distance, ultra-cheap products that are just a single lens element per eye.
