Sun blindness is caused by exposure to large expanses of snow or ice for a considerable length of time.

Make a poultice from the lightly beaten white of an egg. Bandage the poultice on the closed eyes and sleep that way. There should be a big improvement the next morning. Cottage cheese in place of egg white is also effective.

CAUTION: Sun blindness is a serious condition that can lead to cataracts and retinal damage. It should be prevented by wearing sunglasses or goggles.

Preventing Sun Blindness
Skiers find this remedy helpful in coping with large expanses of snow. Eat a handful of sunflower seeds every day. (Buy them shelled, raw and unsalted.)
Within no time, the eyes may have a much easier time adjusting to the brightness of the snow, thanks to the sunflower seeds. . . and a good pair of sunglasses or goggles.
