Inuit snow goggles
Snow goggles (Inuktitut; ilgaak or iggaak, syllabics; ᐃᓪᒑᒃ or ᐃᒡᒑᒃ) are a type of eyewear traditionally used by the Inuit people of the Arctic to prevent snow blindness. The goggles are traditionally made of a piece of bone or ivory pierced with slits but new ones may be made with wood.
Like other Inuit language words, such as inukhuk/inuksuk, a different word may be used in different dialects. In the Kivalliq dialect, ilgaak (ᐃᓪᒑᒃ) is used, while the North Baffin dialect uses iggaak (ᐃᒡᒑᒃ). Both words are also used to refer to sunglasses.
The goggles fit tightly against the face so that the only light entering is through the slits. Soot was sometimes used on the inside to help cut down on glare. The slit is made narrow not only to reduce the amount of light entering but also to improve the visual acuity. The greater the width of the slits the larger the field of view.
The DC Comics supervillan Captain Cold wears a pair of protective glasses modeled after Inuit snow goggles. He does so in order to protect his eyes from the glare of the ice he creates via his Cold Gun.
