The Evolution of Eyeglasses

The Eyevolution of Glasses: EYEGLASSES XXXX Through the Ages If you've thought about the history of eyeglasses at all, you may have assumed that they're a fairly modern invention. In fact, they're actually quite ancient. The first known use of glass to improve vision was in the Roman Empire, during a sporting event. This spawned over 2,000 years of innovation and invention that would help spectators better see, and enjoy, their favorite pastimes. 54-68 ID. O Roman emperor Nero is spotted using a gem to watch the gladiator games. 5 First well-documented use of glass or crystal to aid vision. However, it took about 1,200 years for eyeglasses to appear on the scene. Mid to Late 1200s 5 An Italian lay-person creates the first pair of spectacles. Ɔ Used primarily by monks and scholars working with ancient manuscripts, who didn't have much time for sporting events. Mid 1300s 5 Riveted spectacles are introduced. 5 The V-shape of the frames allows them to be balanced on the bridge of the nose. 5 Helpful to the nearsighted aristocrat attending the popular new game of croquet. 1452 5 The invention of the Guggenh press makes books available to the masses.

Early 1800s 5 Thomas Jefferson becomes the first U.SPresident to order a pair of eyeglasses made. 5 Meanwhile, the first lenses to correct astigmatism are imported. Just in time for folks to check out the new sport of "Base Ball." Early 19 00s The start of World War I cuts off America's supply of ophthalmic glass. Thus begins the company of Bausch & Lomb. 5 Movies (and later, television) create a huge demand for distance -seeing eyeglasses, but Ben Franklin's small, round frames are still in style. Mid 1900s 5 In the 1940s, acrylic lenses pave the way for the plastic lenses of today. In the 1950s, eyeglass fashion hits a new peak. 5 The ladies cheering on Elvis prefer the cat's-eye frames, while men favor thick, black rectangular frames. Their grandchildren will wear the same frames and call themselves hipsters. 1962 5 The first lightweight plastic lens is manufactured. 人 A 人 5 Just in time for people to get a good look at The Beatles. 1970 5 Plastic frames overtake metal as the material of choice.
