Eye glasses and their development over the years shows us how things that we assume to be much more modern than they really are can trace their lineage back to the ancient world, in some cases. This is the actual case with glasses or spectacles, which has been with us in some fashion going back to when the Egyptian pharaohs and their civilization was the dominant power in the world.
The technical definition of “spectacles, ” or “glasses” today are that they are frames that hold lenses which are then placed in front of a person’s eyes to aid in correcting vision, in protecting the eyes from harm or to guard against ultraviolet radiation or all three at once. Given the development of fashion, it should all be said that some are worn strictly for fashion purposes nowadays.
There have been a number of versions of spectacles down through the centuries, also. This includes the monocle (which is a single eyeglass lens), the pince-nez (worn on the bridge of the nose and held there by a pair of pads on either side of the nose) and other types, including highly stylized scissors-glasses, which sat on a Y-shaped frame and were used to correct distance-vision issues.
Scholars have identified references to the ability to use glass to magnify going back as far as the ancient Egyptians of nearly 2800 years past. There are writings from the first century from a teacher of the Roman ruler Nero that mention how looking through a glass of water could improve the ability to read writing, and Nero is known to have used a gemstone to look at writings.
The Arab scholar and inventor Abbas Ibn Firnas, who lived in the 9th century, is credited with producing what are thought to be the first corrective lenses. He’d worked to develop extremely clear glass and put these glass stones to work in viewing objects and writings. An actual shaped convex lens was discussed in a book on optics dating from the year 1021.
The 13th century seems to have been a time of much work and experimentation on spectacles and glasses. Scholarly works from 1235 made mention of how certain kinds of class could be used to greatly improve reading vision, for one. The Chinese of the 12th century are credited with actually producing the first pair of fashion sunglasses, which were used to help reduce glare, by the way.
The first actual pair of eyeglasses that could be worn regularly are thought to have been invented in 1284 in Italy. Most scholars agree, at any rate, that they came into being at some point between 1280 and 1300, and were invented in Italy. The great American inventor and statesman Benjamin Franklin invented the first bifocals in 1784. Corrective lenses were developed in 1825.
Since then, eye glasses have been a part of our lives in ways both big and small. People of all ages where them nowadays almost without a second thought and, in many instances, life would not be bearable without them, especially when considering the vision problems that many people are either born with or develop. They have had a long life with us, as a matter of fact.
