Ryan,
When doing AP, focus should be set as close to technical perfection as possible, not to suit the imager's eyes, [unless you don't expect anybody but yourself to look at your pic.] Your camera's auto focus system doesn't attempt to focus to suit your eyes, it gets as close to technically correct as its designers ability allows. The stunning Nat.Geo pics are focused as close as possible to technical perfection, not to the imager's eyes. If all our members posted their pics focused to their eyes, some of the pics would be quite awful.
If one's eyes are not crash hot, one wears appropriate glasses or lenses
in order to see nice sharp pics. If I focus using live view I have to do that with my glasses on; with a mask it doesn't matter whether I wear glasses or not. Of course some people have really bad eyes, and glasses won't them, but that's another story. A Bahtinov mask [or other focal assistance] allows everyone to see your image as you would like it seen.
