"Snowblindness is caused by brilliant reflections or glare from the snow. It can occur even on foggy or cloudy days. The first warning of snowblindness comes when you no longer detect variations in the level of ground, followed by a burning sensation of the eyes. Later your eyes pain when exposed to even a weak light. Prevention is the best cure, but if you are stricken, complete darkness is your best medicine. Wear your sunglasses or other material with narrow eye slits cut in it (fig 185)."
