Optical glare

I was watching NFL football last Sunday and was wondering
why (American) football players wear grease paint
under there eyes but other athletes don't. Does the grease
paint really reduce glare, or is it, at some level, more
like war paint? Would grease paint make my eyes more
comfortable in snow and sun glare conditions? Would
war paint help me to ski faster?

I was also wondering about full contact ski racing,
but I don't want to get too far off topic here.

The Inuit of centuries past, before the invention
on dark lenses, wore snow goggles that had a
series of one or more horizontal slits. Northern
Europeans and Asians probably had something similar.
I'd like to try something like that for skiing.
No worries about fogging, plus you'd look a little
scary. Does anyone know about the type of eye shades
I'm talking about? A Google image search on
"Inuit snow goggles" (*) turns up some examples
of the one slit variety. Multiple slits would probably
work better for skiing... (?)

I just wear sunglasses. Simpler, readily available and they work pretty well
plus they are easily available on ebay - cheap....

cheers

- - Baseball outfielders sometimes do as well.

_ The theory is to reduce the reflections off your cheek bones as
you look up into the sky. On lineman it's just war paint. Unless
you have some very strange ski technique, I suspect it wouldn't
help much.

_ BTW, you can make your own slit glasses with sunglasses and
duct tape. It's an old mountaineer's trick for dealing with
snow blindness. ( Much MUCH better to avoid in the first place.)

One year the whole Swedish ski-orienteering team turned up at the
starting line for world championships with grease paint beneath
their eyes. It was an interesting idea but I never saw anyone
else try it, nor did I hear afterwards if it helped them.

In cross-country the easier thing to do is to just wear sunglasses.
Unfortunately sunglasses can cause problems in ski-O due to the
tinting changing the appearence of the colors on the orienteering
map. This would not seem like something that should cause
problems, but I tried racing a few times with sunglasses on sunny
days and I always made at least one navigation error that was
directly due to mistaken color perception when reading the map. I
eventually made myself promise to never race ski-O with sunglasses
again. I toyed briefly with the thought of trying the grease
paint, but I had no idea what exactly it was or where it could
be purchased and never bothered to find out. :-)

Try neutral grey. In film making, NG gels are used specifically to NOT
shift the color. I think any lens that really appears to be grey would
work. Perceptions might vary, bring your maps along to check (and make
sure you try them out in daylight (5000K black body) instead of the
store's greenish flourecents or purplish halogens . . .
