make your choice up front and stick to it, wearing eyeglasses or not (take off, put on repeatedly is a pita though) If do not wera your eyeglasses, do get a good set of shooting glasses
CONSISTENT head position, extremely CONSISTENT, always important in scope shooting, all the more important now
concentrate on consistent head position and cheek weld... get used to pushing eyeglasses up on your nose every shot, or use elastic to hold 'em up... slowing down a tad when shooting for "groups' never hurt anybody nohow
adjust eye relief to your very consistent head position, adjust crosshair sharpness focus to max no matter what your consistent default head/cheek position is (as was advised above, not staring through scope, close and open eyes until just right)
do NOT focus on the target (do adjust AO, if have one for a clear, sharp target view) but FOCUS on crosshairs, NOT on target, same way you would focus on a front sight for open sights or peep sight
(I wear progressive lens eyeglasses)
perverse as it may seem, eyeglasses just force you to pay closer attention to the basics which you might not otherwise
have FUN !
