I resisted higher powered scopes due to size and not feeling the need for them a long time. Probably had nothing to do with aging at all. But finally bought some higher powered variable scopes and I can certainly see better with them via the higher power settings. Much like my new Kowa spotter has more Xs than my older Zeiss did. More power has made it easier.

Plus, "Honey I'm getting older so my eyes could really use that 4-16 ATACR" worked well for me.
