Wait, what? Doesn't eyeliner go on your eyelids? How would that prevent snow blindness?
I'm as lost as you.

Prevents reflected glare. Which is why it is put on the underside of the eye. The heavily underlined eyes and "Eye of Horus" motif seen in ancient Egyptian artwork have a very practical basis.
Horribly simply put, snow and sun glare reflects from the cheekbones and eye-sockets onto the retina, causing sunburn. And no, sunglasses don't help unless you're wearing full-on goggles. There's enough leakage around the edges that, with the sunglasses encouraging the pupil to dilate, you're doing even more damage than you think.
Been snow-blind once. Not a pleasant thing. I take precautions now.

also used in (american) football. they call it eye-black or black-eye to do exactly what Njall said.
But what everyone is confused about it how you go from eyeliner that goes on you lids to paint/grease/whatever you put on your face to reduce sun light to your eyes
also I just started reading this threat at page 9 to find smutty books, eyeliner, and someone handing in his manly card....

Possibly because that is what khol was originally used for.

Re: Cool Worgen Names
I .... think you might have been fooled by a urban legend. Wikipedia's Eye of Horus page doesn't make any mention of a practical use, just a religious significance. The Snow Blindness page corroborates the need for "full-on goggles" instead of sunglasses, which makes sense.
However, the contribution due to eye sockets should be negligible, and eyelids should be zero (you can't see your eyelids, after all). Your skin does not "reflect" in the strictest sense, it scatters. That scattering process reduces the intensity very significantly, because it's omnidirectional. So for light that hits your eye socket, you'll only get maybe 10% of that light scattered in such a way that the eye can capture it and image it to the retina. Given that I can only barely see my eye sockets already, that's not going to be a lot of light. Certainly nothing compared to what "leaks" in around a small pair of sunglasses. Multiple scatterings (i.e. from eyelid->eye socket -> eyeball) are going to be even weaker.
I don't believe that you'd be able to tell the difference between eyeliner and no eyeliner. For any regular pair of sunglasses (where you can see the world untinted in your peripheral vision), the oblique light is going to be a far bigger factor. For a pair that were as large as your face, maybe the only light that could reach your eye would be from reflections off of your eye sockets, and it would become relevant. But if that incidental exposure, accumulated over a few hours, was enough to cause snow blindness, then the ambient light would have to be so intense that taking the glasses off for even an instant would render you blind.
Though that brings up the interesting question of why they do it in football.

Re: Cool Worgen Names
Well eye-black, or whatever it's called, in football doesn't go on your eyelids as far as I was aware. I thought it went right below your lower eyelids and slightly onto the apples of your cheeks. My understanding was that this was to prevent possible glare which could possibly be caused by sweat but it also doubled as sunblock since cheeks can tend to burn rather quickly if they're prominent on the face and exposed. (I didn't look any of that up, but I will now just to find out if I'm close to the truth.)

I wasn't far off. It's to prevent the glare from the stadium lights.

Re: Cool Worgen Names
The bit about ancient Egyptians is what gave that impression. As far as I know, they outlined their eyes, but they didn't put it below their eyelids.

Clearly you've never spent extensive time in a desert or arctic environment. BS science vs. what folks actually do in those environments in modern and ancient times. As I said, been there. Done that. Got the snow blindness. Got the desert glare. Logged the sick time. Survived the tours.

No, I certainly haven't. And I have no doubt that you've endured snow blindness. But I'd hesitate to call 200 year-old basic mathematical and physical principles like Solid Angle and Scattering theory "BS science."
Folks doing something doesn't mean it's not a superstition or misunderstood. I can believe that using eyeliner prevents glare, and might make working in such an environment more comfortable, or prevent sunburning the skin in those areas. I have more trouble believing that the amount of light entering your eye due to scattering off of cheeks and eye sockets is a significant percentage of your total light intake, or that using eyeliner to cover those areas would make a significant difference in exposure that causes snow blindness.
<edit> I did some simple googling of snow blindness and various makeup terms, and didn't turn anything up that indicated this sort of usage. Do you happen to know of any medical research done in this particular area? I figure you've "been there, done that," which means that at some point someone gave you the reasoning behind this, and might have provided you with sources. Or you might just know where to find them, given that you work in this area.

Re: Cool Worgen Names
Mythbusters busted the "war paint" myth awhile back. Putting it on your cheeks/eye sockets doesn't do much of anything - that's why football helmets have polarized shades on them and baseball caps have bills.
Oh, and kohl was originally used as makeup, same as rouge. It's the equivalent of eye shadow, not eyeliner. It was used to darken the eyes to give a more mysterious appearance by deepening the shadows in a person's orbit, same as rouge was used to give a bright, youthful "rosy cheeked" appearance. And before the invention of rouge, women used to pinch their cheeks until they were red for the same reason.

Big chunks of "Secrets of the Ruined Temple." Ken Hite wrote all the crazy Atlantis stuff - he is simply an amazing guy. I wrote all the Indiana Jones stuff and the sample adventure. I stole one of the archaeological sites I worked for as a template.
Any time where I can write "the obligatory rolling boulder" I realize that life is good.

I think he means eyeshadow.
