How do you keep your eye from going blurry while shooting bullseyes with iron sights? I do not have this problem with optics, but with iron sights my eye will start going blurry after about 10-15 shots. I almost get to the point where I can't really focus on either the front sight post or the target. They both get a halo like outline. I have 10 minutes to shoot 5 rounds into 5 different bullseyes, and my eye will go blurry about halfway through.
