Being in my 40's, my eyes are having trouble picking up the sights. If I use glasses to see the sights, tyen I can't see the target and visa versa. Does anyone have a possible solution? I've tried 3 dot and I can't see the dots. I've tried Prosights and can't pick up the "V" too well. Indoors you can forget the Prosight. Has anybody tried the fiber optic with the traditional notch?
