What Was The Strange Origin Of Sunglasses? #Shorts

What was the strange origin of sunglasses?

Sunglasses, now common throughout the world, were actually invented for a reason other than to protect the users eyes from the sun. While inuits have used sunglasses for millennia in order to protect their eyes from snow-blindness, these were only made from pieces of bone with slits cut in them, working by decreasing the eyes exposure to sunlight rather than decreasing its intensity. The first transparent sunglasses were actually invented in 12th century China, known as Ai Tai, or ‘dark clouds’, they were made from smoky quartz lenses which were created in order to conceal the expressions on judges faces during trials.
