Just tried out my new Radians cheapo bifocal shooting glasses that I bought off of amazon. IMO I have to lean my head back to see my gun sights through the bifocal section which feels unnatural. With my drugstore reading glasses I can do better job of positioning them where I want on my nose and then all I have to do is tilt my head slightly Not so with the Radians. They'll make so-so work glasses. I then flipped the Radians upside down to simulate the Hansen eagle Eye glasses with the bifocal section on on top and that feels natural on account that people lean their head down when looking through gunsights. But when I tilt my head,my head is out of alignment with my gun sights. Maybe I'll just use my Crimson Trace laser and just point and shoot.
Mudfoot,I think the Crossman red dot sights might be the thing for you but you most likely be needing some kind of corrective lens glasses to go along with it. I just ordered my first red dot sight for my Tanfoglio Appeal Bullpup 22LR. Guess I'll mount that next to my scope.
