Farsighted men and nearsighted women

[mtbc]

I was thinking about the traditional image of primitive humans with men going out on hunting parties, looking for fauna that may keep its distance, and women foraging for nuts and berries, doing close-up scrutiny of the flora. I then searched a little on PubMed, another useful US government website. A glance at the literature does indeed suggest that the hyperopic are disproportionately men and the myopic are disproportionately women. While I am pleased to so easily find seeming support for a casual hypothesis, I am loath to credit how I arrived at it from a storybook view of prehistory that, as I vaguely recall, significantly differs from what is now believed.
