Ive got a few years on you and know what you mean about eyes so.
My personal favorite is 4x as it lets me see the target way better than a 2x or a dot and I have both.I have never felt over scoped with the 4x ,but have wished for more magnification before
with the dot and 2x. 4x allows me to[ pick the spot better]
I. M. H. O .
Try the one ragged hole peep on your open sighted guns as it helps a lot,allowed me to kill my buck this year at 60 yds 5 1/2 in Bisley .45 colt.
