I got real bad eyes too, years of reading repair manuals with dirty hands and too lazy to wash my hands and get glasses.......... But the 45x I have is too much for even me.
I just bought a pocket microscope on Ebay for ten bucks. It's a lot of fun. It adjusts to 60x-100x magnification and lets you adjust the focus and has a built-in light. I've been magnifying everything in my apartment.
