Ringman,
"I" is the operative word in your post.
Your eyes can not use the exit pupil, so you do not get the benefit.
With higher magnification resolution always increases - the exit pupil decreases.
Anybody able to utilise the full exit pupil will notice the scope "darkening" as magnification increases.
They will also notice resolution increasing - as to you.
You only see one of the two happening - due to you personal situation. And you draw the wrong conclusions.
Also - when turning up the magnification to 15x still lets you distinguish deer antlers with an exit pupil of 3.3 mm, it is in the real world bright daylight still.
Also I know, my healthy young eyes would resolve still same antlers for me with your binos.
I do sympathize with you eye situation and am glad the higher mags keep you in the game. I also realize to enjoy my good young eyes while I can - age comes at it own speed invariably.
That said -
I urge you to never forget - that below your riflescope is a barrel. Scopes are for aiming; not for identification.
second - try to view the interdependencies in optics. What you see is only half the story and you are drawing the wrong conclusions.
Keep learning - its the smart thing to do.
