Since I'm getting 'on' a bit, I have gone from perfect eyesight to needing glasses for everything. I wear bi-focals now and I'm having a very hard time at the range trying to see sights. It's a bit frustrating. Anyone else have this problem or have any suggestions to make this any easier ? Was considering just wearing readers.....the target might be a little blurry, but at least I wouldn't have to crain my head back to get the sights in focus.....gettin old ain't easy....
