In spring when snow shines in the bright sun, peoples of Siberia, in order to protect the eyes against snow blindness wore special goggles, which were two round or oval copper plates with narrow slits sewn in a deer suede or cloth bandage. Men wore them for the journey, going out hunting or to a pasture. The goggles were tied on the back of the head with deer suede strings.
