When it comes to scopes, just be aware that aging-related farsightedness and, moreover, wearing corrective eyeglasses, may well play havoc with using a scope. This, because the image you're looking at in the scope is only a couple inches from your eye. Focusing slowed by age will make it even worse.
I've been having a heck of a time seeing the image in a scope while wearing my glasses, which I need for anything more than arms-length away. Helpng a friend sight in his rifle earlier this fall, I had to ditch my eyeglasses to see the target through the scope, which would have been impossible in a hunting situation. I've always tried to shoot with both eyes open, especially because I don't want to create bad habits for shotgunning, and that gets awkward with one eye on the scope (seeing a very clear image) and one looking downrange (seeing mud). I'm actually considering ditching the scope and going to a ghost ring sight for my rifles. Most shots here in Maine are under 100 yards, so I don't think I'll be losing out going that route. The other alternative would be going to a scout-style setup, but that means drilling new holes, something I'd rather avoid.
A high quality CQB (Close Quarters Battle) style 1-4x scope, like a Nightforce Compact NXS 1-4, set on 1 power, may be the optimum sight for reasonably close range shooting. It can be shoot both eyes open, just like a shotgun, quickly and accurately. There should be no problem in using the scope with eye glasses on as long as it is adjusted properly.
