After years of using scope sighted rifles, I recently picked up a rifle with open sights. I can see the front sight and the target, or I can use my bifocals and see the rear sight, but not the front sight or the target. I was wondering if any others challenged in this way found aperture sights a good compromise. Since the rear sight is fuzzy anyway, and it is supposed to be blurred with the front sight centered in the blurry field and on the target, it seems this might work for me. But before I bought a set, I thought I would see what others of my vintage had to say.
