Snow blindness, also known as [photokeratitis][1], is predominately caused by the sun's reflection off of snow.  If one is caught out in the wild, ill prepared for snow, **what could one find in a temperate forest to help prevent snow blindness?**.

Two options I was wondering about are:

 - Improvised [No Glare][2] from charcoal/ashes like what professional
   athletes use.  However, I'd question it's ability to block reflection
   from snow and I'd be worried about getting it in my eyes.
 - An improvised hat, but again I'm not sure that would help much with
   reflection off the snow.
