Where did the first sunglasses come from?
Sunglasses have an ancient origin. In prehistoric times devices made from tusks with small horizontal slits in them were worn to reduce the glare from the sun. Colored lenses of a sort were worn in Greek and Roman times. An optician named James Ayscough began making glasses with tinted lenses in the mid 17 hundreds. He didn't make them to protect from the Sun rather to alter vision. Sunglasses for the masses were first sold by Sam Foster in the 1920s. He named them Foster Grant's. Does that name ring a bell?
