This problem is one most older shooters must face. I have been struggling as I age with corrected vision and target shooting. I am mainly a hand gunner and use contacts, although I own bifocal glasses. It seems like I have a choice of seeing my gun sights clearly, or the target clearly, but not both. Full distance correction really doesn't work for me, since I have always relied heavily on a classic sight picture. I shoot best, when I use a reading contact lens in my right (sighting) eye. That way I get a clear sight picture, but a useless target picture outside of ten yards. I have tried a contact lens cutting the difference half way, but I find I shoot best with a reading lens, if I can figure out where the center bullseye is! How do the rest of you older competitors deal with the dual vision issue?
