Eye appointment update: Turns out my VA eye doctor is a shooter too. My question to him concerned sight picture for open sights. I need glasses for reading but can't see far away with them on. If I shoot with my reading glasses on, I can focus pretty good on the rear and front sights but the target turns into a blob. This happens with long and hand guns. Note: I normally wind up shooting with just my safety glasses on, not my reading glasses. This leaves the sights fuzzy but I can see what I'm throwing a bullet at.
His answer to me was, put a scope on it. Anytime I am target shooting or hunting, scope it. He said this is the #1 problem for shooters, as far as changing eyesight. Plinking is just that and who cares if you miss a can by a little bit. For targets and killing, you want to have the best vision on sight and target, and for that, it will take a scope. He said there are some doctors that might recommend a lens surgically implanted but there have been mixed results from those types of things.
My entire life, I have only shot two rifles and zero hand guns with a scope. Looks like that might be changing soon.
