Sunglasses are one of the world's most ubiquitous fashion accessory, but also play an important part in protecting our eyes from harmful UV rays. We take a look at how they came into being...
Snow goggles: the first sunglasses
The earliest known use of glasses to protect eyes from the sun was the Inuit use of “sun goggles” to shield their eyes from the blinding glare of light reflected off the snow. These were made from carved driftwood, bone, walrus ivory, or caribou antler that formed a strip worn across the eye area, with thin slits that the wearer could see through. The goggles were cut so that they fit tightly to the face, and often soot or gunpowder was rubbed on the outside to absorb the light and further cut down on glare. The use of these goggles dates back to around 2,000 years ago, and as a bonus, even improved the wearers vision as the narrow slits helped focus eyesight.
The Inuits weren't the only people in history to find an innovative way to protect their eyes from glare: Pliny the Elder wrote in his Natural History that the Roman Emperor Nero used to watch the gladiator fights through polished gemstones to reduce the glare from the sun—potentially the most expensive and most ineffective form of sunglasses in history. Another form of eye protection also cropped up in 12th century China, when flat planes of smoke-tinted quartz lenses were worn by magistrates in court proceedings. However these were supposedly used to hide the expressions of the wearer, not while outside catching rays.
By the 18th century the modern form of eyeglasses had been invented, made with lenses held together by wire and the frame extending over the ear to hold them in place. A man called James Ayscough believed that changing the color of the actual lens could further help with specific vision impairments. He experimented with blue and green-tinted glass as ways to improve poor eyesight—little did he know that his idea would go on to be one of modern day’s must-have fashion accessories.
The dawn of modern sunglasses
The first instance of lenses being used to actually protect a wearer’s eyesight from light was around the early 20th century, when yellow and brown tinted glasses were prescribed to sufferers of syphilis. Syphilis causes eyes to become sensitive to light, so wearing darkened spectacles would have eased discomfort. However, not long later, sunglasses stopped becoming associated with poor health, and began to be a symbol of celebrity.
Around the 1920s, it became common for famous movie stars to be seen out in public wearing sunglasses. Not only would shielding their eyes make their identity more covert when they didn't want to be noticed, but it hid the fact that it was common for actors to have red eyes due to the powerfully bright klieg lamps used in studios.
Where celebrities go, fashion follows
With the trend firmly set by the glamorous stars of the era, the demand for sunglasses skyrocketed. Savvy businessman Sam Foster began mass-producing sunglasses made from celluloid in 1929, which he began selling on the beaches of Atlantic City in New Jersey. The market was willing with their appeal stretching beyond sun-soaked beaches, and by 1938 Life Magazine reported that sunglasses were a: “new fad for wear on city streets...a favorite affectation of thousands of women all over the U.S." The same article also stated that in 1937, 20 million pairs of sunglasses were sold, but only 25% wore them to protect their eyes.
Polarized lenses, which contain a special filter invented by Edwin H. Land that blocks intense light reflected off other surfaces like sand or snow, became available in 1936. Ray Ban, a glasses brand founded by American eye health company Bausch and Lomb, created aviator-style sunglasses using polarized lenses that were widely used by US Air Force pilots during World War II to block the glare from the sun. In 1937, they went on sale to the public and function finally met fashion with the shape of frames and color of lenses changing drastically to keep up with the catwalk.
