Everything I read and hear about shot placement emphasizes focusing on the front sight as one of the most important elements of accurate shooting. Since I have been far-sighted for a while, I cannot get the front sight in focus (unless I tilt my head back to bring the bifocals into play!). The target, however, is crystal clear. So, what can I do about that? I know I'm not the only older guy out there. What do you other "focus-challenged geezers" recommend?
