This website talks about the Inuit cultures and the types of snow goggles that they used in the past and how we have adapted that technology into a more contemporary style. they also tell a little bit about the cultures of the Inuit people. it also talks about the construction of the goggles as well as the travel of the people.

What Snow Goggles are made from

in the Inuit cultures the snow goggles are usually made from walrus tusk, animal bones, or antlers. The Inuit (Eskimo) Cultures include the Yup'ik, Inupiaq, and Inuit(Canadian). these cultures dont have a steady flow of resources due to the harsh northern climate so it oriented what the goggles were made out of. some of the more southern cultures such as the Tlingit and Athabascan cultures use a different method to making their snow goggles. the southern cultures have a steady flow of resources unlike the north. so they are almost always made from wood or antler. then the Aleutian culture uses mainly drift wood and bone for their snow goggles. 

The amazing snow goggle

this is a cool picture dipicting how the different styles of snow goggles from different areas are still similar and work similarly but they also have their slight variations. it is so interesting when you look at the tools the Alaskan Native peoples had before colonialism. snow goggles is one of the very few items that every region has a history of using them.
