Inuit snow goggles function by reducing exposure to sunlight, not by reducing its intensity
In prehistoric and historic time, Inuit peoples wore flattened walrus ivory "glasses," looking through narrow slits to block harmful reflected rays of the sun.[3]
It is said that the Roman emperor Nero liked to watch gladiator fights with emeralds. These, however, appear to have worked rather like mirrors.[4] Sunglasses made from flat panes of smoky quartz, which offered no corrective powers but did protect the eyes from glare were used in China in the 12th century or possibly earlier. Ancient documents describe the use of such crystal sunglasses by judges in ancient Chinese courts to conceal their facial expressions while questioning witnesses.[5]
James Ayscough began experimenting with tinted lenses in spectacles in the mid-18th century, around 1752. These were not "sunglasses" as that term is now used; Ayscough believed blue- or green-tinted glass could correct for specific vision impairments. Protection from the Sun's rays was not a concern for him.
Yellow/amber and brown-tinted spectacles were also a commonly prescribed item for people with syphilis in the 19th[dubious – discuss] and early 20th centuries because sensitivity to light was one of the symptoms of the disease.
Modern developments

Effect of pair of polarized filters
In the early 1900s, the use of sunglasses started to become more widespread, especially among stars of movies. It is commonly believed that this was to avoid recognition by fans, but an alternative reason sometimes given is that they often had red eyes from the powerful arc lamps that were needed due to the extremely slow speed film stocks used.[citation needed] The stereotype persisted long after improvements in film quality and the introduction of ultraviolet filters had eliminated this problem.
Inexpensive mass-produced sunglasses were introduced to America by Sam Foster in 1929. Foster found a ready market on the beaches

    Ray-Ban History

    • 12 Pages

    1936 Birth of Ray-Ban Eyewear For aviation, both military and civil, the 1920s was a decade of remarkable advances. Air traffic grew as a result. With the development of new aeroplanes that could fly higher and higher came altitude-related problems. Pilots were suffering from headaches and nausea because of glare and the great distances that they had to traverse. In 1929, General MacCready asked Ray-Ban for a new type of air force eyewear that would protect pilots from glare at high altitudes while at the same time ensuring a clear field of vision. The company took up the challenge and succeeded in developing a new pair of glasses with lenses that could block out a high proportion of visible light. This marked the birth of Ray-Ban’s first, green-lens ANTI GLARE eyewear. The first model to go on sale to the public - in 1936 - featured a plastic frame with the classic Aviator shape. 1937 Ray-Ban Trademark Registered The name ANTI GLARE was too generic. It did not distinguish the new eyewear clearly from rival products. In 1937, the Ray-Ban trademark was registered and marketed, gracing a new model with a metal frame. The name Ray-Ban was chosen for the new product to emphasise that the eyewear could block out glare and protect the user’s eyes from the sun’s rays. The Large Metal model immediately leapt to fame with the name Ray-Ban Aviator. 1938 Early Ray-Ban Models During the early years, Ray-Ban’s marketing strove to foreground the functional aspect of the new eyewear, targeting sports enthusiasts and lovers of the outdoor life. In 1938, the first Shooters were launched. These were available in two types of lens, Ray-Ban Green and Kalichrome, a pale yellow lens for use in misty or foggy conditions. Shortly afterwards, a third, ground-breaking, metal-frame model hit the market. This was Outdoorsman, originally called “Skeet Glass” and designed for specific user groups such as hunting, shooting and…
