This must be a common problem. As I've gotten older, my near vision has gradually gone to hell, to the point that at an indoor range with low lighting, I can barely focus my eyes on the sights. If I try hard, I can do it for a little while and am accurate, but then my eyes get tired and my accuracy drops because the sights become little blurs and I have to guess where I'm aimed. This is less of a problem outdoors in bright sunlight. Short of a scope or laser, what do other folks do to help with this problem? Reading glasses would bring the sights back into focus, but then the target would become blurry - maybe that's still an improvement, I haven't tried. Bright headlamp? Fancy glasses with mirrors and diopters?
