I'm in that category - I've noticed is that me and other mountain climbers and hikers seem to age better. Could be selection bias - the unhealthy with poor eye

  I doubt that that's a key factor. There's a lot of luck on initial refractive error, etc. I don't need reading glasses. One reason is I have one eye with a slightly near refractive error and one with a slightly far refractive error. They're also both pretty close to nominal, so losing a bit of range on focusing doesn't hurt as much as if I'd been biased one way or another. I do notice that I prefer slightly larger text than before. I bet if I tried reading glasses that I'd find that they lend some benefit.

  I notice that after a long hike in the mountains, I can see a bit better. The effect stays for several hours. Probably the eyes need some training too, refocusing onto near and far objects frequently. We live in a computer screen world, this is very unnatural for our eyes.

    Maybe it’s from focusing to infinity for a long period of time.
