Only that more further testing, on more diverse groups, did not
significantly change the results...
Proving that our adaptive visual system nulls out any differences in the
brain where vision takes place, and the same thing happens by averaging
the differences between right and left eyes. Like most people, I had
different color perception between my eyes for most of my life (for some
strange reason I no longer have this), but if I looked through either on
it's own long enough, it would adapt to showing the 'correct' color,
thus exaggerating the difference when I'd switch to the other eye. When
both eyes are being used and I quickly shift from one to the other,
there'd be less difference between them. I suspect that in the end, it's
all about the same once the brain adjusts the signal it's getting to a
comfortable white point. Pretty freaky to be in this business and know
this is happening, but that's why we use measurement tools to help.
