The oldest sunglasses in the world
The World’s Oldest Sunglasses | Canadian Museum of Civilization
Enough sunglasses were first used not in tropical countries where the sun bakes and shines brightly day after day, but in regions of the Far North.
Eskimos and other peoples of northern regions know firsthand what snow blindness is. In springtime, the intensity of sunlight increases, there are more and more clear days, and therefore the sun’s rays are perfectly reflected from the crystal snow. Even within the city limits, it's painful to look at the snow on a bright sunny day. Imagine what it would be like to look with unprotected eyes at a boundless sea of snow somewhere in the Arctic? It’s very easy to get eye damage in such conditions.
Our distant ancestors who lived in these harsh regions had to look for ways to protect themselves from the bright sunlight. Lacking modern materials capable of dimmer light, they logically came up with an invention capable of reducing the intensity of the flow of sunlight to the eyes. This is how the world’s first eyeglasses with narrow eye slits were created, which became the prototype of today’s sunglasses. These eyeglasses had a very restrictive vision, but they allowed you to move around even in the blinding sunlight.
Usually such glasses were made of wood or animal bones. The most ancient sunglasses were discovered during the study of the sites of ancient Bering sea culture, which lived from the 3rd century B.C. on the coast of the Bering Sea. The age of this find is about 2000 years.
