Size is not as important as structure, but as the paper in my previous link indicates, the larger the animal, the smaller (in relation to body size) the eye. For instance, if we had similar eyes to those of loruses etc, they would be the size of grapefruits.Krantz didn't think such adaptation would be necessary because the sheer size of the eye would allow for admission of a lot of light even at night.
As we and our immediate cousins in the animal kingdom (and all of their/our ancesters) do NOT have eyes of this size, I don't think his conjecture is valid. It doesn't seem to be based on any scientific or evolutionary/fossil evidence to date.
Irrelevant to the discussion - as you made a point of correcting me on, YOU are talking about higher Primates, not ungulates.I remember being astounded in Seattle in summer that I could still see quite well at 10:00 PM.
