Out of curiosity are you male? There are physical differences between men's and women's eyes where men's eyes are better at edge and motion detection and women's eyes are better at detecting the difference between blue and green.

Or at least adults are, possibly because of the environment they grew up in (the science is still murky on that one).

Some women are even tetrachromats, with four different color receptors (it’s pretty rare).

[jedberg]

That's orthogonal though. Both men and women can be tetrachromats, it's just more common in women (but exceedingly rare in both populations).

Yes; thanks for pointing that out, that's an important factor too, I guess.
