They adapt for all of those winter reindeer games.

Hmmmm....God is...er, I mean, evolution is sooooo impressive.

You'd mentioned in a previous post that the Sa'ami may have unique eyes. Looks like their reindeer do.

Sami's

"Reindeer have a different set of eyes for summer and winter, a new study suggests"

SOooooooo, If you accidentally blinded one in summer it would be seeing fine by winter? I wonder where they store the spare set?

Thanks. I'm still wondering about the blue-blindness, and it makes some sense if you don't have any blue cones and simply rely on your rods to supplement the signal for color purposes.

The chemistry to sense "blue" light is also different from that used to sense "red" and "green", and it responds slower. In the arctic day, the "blue" lagtime might well lead to early degradation of the retina ~ maybe in the form of a retinal neuropathy, or macular degeneration.

The extra complement of "red" receptors has an arctic night advantage.

Hey, if they can pull a sleigh to every house in the Christian world in one night, they can probably do anything!

OK, Blam, here I am 10 full months from my last cataract surgery. Back in March when this thread was alive and in living color I was still wearing sunglasses at night. Little did I know that in just a couple of weeks my eyes would suddenly adapt and I could throw away the sunglasses.

Imagine my surprise when I discovered that my eyes had changed from GREEN with a black rim to BLUE, and not just blue, but a deep, penetrating hard blue ~

They've subsequently changed from that to a blue border around an orange center.

I suspect that as the days grow shorter and we head toward Christmas they'll go back to BLUE.

It seems logical that the human beings who successfully track/herd reindeer have to see at least as well as theiry quarry.

...eyes removed from animals culled in winter appeared deep blue when light was shined into them.

They're dead, James.
