I wear glasses for reading. I am far sighted, and can shoot a rifle, with or without a scope, without issue. However, close range presents a problem. I have bifocals, and focusing on a close target, and sights presents an issue. I have to tilt my head back to see the sights, and then back forward to see the target. I can never frame sights and targets at the same time. The main reason, I will never be a competition shooter. Oh to be young again. Any advise, or tips appreciated.
