Further to Paul's note on diopter reading glasses, if you do a search for Computer or Reading glasses, you should find a site that sells them as light as .25 and .50 dipoter.
These work quite well and don't fuzz the target too badly. The lightest dipoter I could get at an optometrist's store was .75, for me, these make the sights the best, but the
target is quite fuzzy. The lightest I found in regular stores pharmacy's reading glass 'racks' were 1.0 dipoter.
I still shoot with just my regular prescription glasses and fuzz my way through, although now and then, I re-try the reading glasses. I always go back to my bifocals as I need
their higher "reading" magnification to see what I'm doing with the loading.
