While even in prehistoric time Inuit peoples wore flattened walrus ivory glasses to block harmful reflected rays of the sun, the earliest historical reference to sunglasses dates back to ancient China and Rome. The Roman emperor Nero watched gladiator fights through polished gems.
In China, sunglasses were used in the 12th century or possible earlier. These sunglasses were made out of lenses that were flat panes of smoky quartz. They offered no corrective powers nor they protect from harmful UV rays but did protect the eyes from glare. Ancient documents describe the use of such crystal sunglasses by judges in ancient Chinese courts to hide their facial expression when they interrogated witnesses.
James Ayscough began experimenting with tinted lenses in spectacles around 1752. Ayscough was steadfast in the belief that blue-or green-tinted glass could potentially correct specific vision impairments. Protection from the sun’s rays was not a concern at this time.
Glasses tinted with yellow-amber and brown were also a commonly-prescribed item for people with syphilis in the 19th and early 20th century because one of the symptoms of the disease was sensitivity to light.
In the early 1900s, the use of sunglasses become more widespread, especially among Hollywood movie stars.
Modern Time :
Inexpensive mass-produced sunglasses made from celluloid were first produced by Sam Foster in 1929. Foster found a ready market on the beaches of Atlantic City, New Jersey, where he began selling sunglasses under the name Foster Grant from a Woolworth on the Boardwalk.
And now we have them from very expensive to almost through away kind. But whatever you favorite kinds are where them not only for eye protection but they look cool. Lisa
