Maybe they had better vision. too.

I heard a story about this, but I can't find it on the internet and don't remember the details. Something about someone giving an elder aboriginal glasses, and him saying like "it's better, but I still can't see (thing he used to see, which IIRC was a star) like it used to.



Interestingly, several cultures actually used the number of stars a person could see in the Pleiades as a vision test.



Not all factors causing poor vision in the elderly can be solved with a pair of glasses


They sure had less light pollution!
