"In winter and early spring, the light of the Far North
reflected by the snow and ice is of rare intensity. To protect the eyes, the
Inuit therefore imagined a long visor and glasses, whose small circular or slit
holes let in very little light. Set against a decorative background typical of
the Bering Strait region, visors and glasses from the nineteenth century adorn
this square. The visors of the lower Yukon, Alaska and Kodiak Island are
adorned with ivory, Arctic duck tail feathers or sea lion whiskers. Walrus
ivory glasses date from 500 to 2000 years ago."
