History of Eyeglasses and SunglassesThe inventor of the first spectacle lenses is unknown. Roman tragedian Seneca (4 BC -65AD) is said to have used a glass globe of water as a magnifier to read ”all the books of Rome”. It’s been reported that monks in the middle ages used glass spheres as magnifying glasses to read.The 13th century Venetians glass blowers are known to have produced reading stones made of solid glass that was put into hand-held, single lens-type frames made of horn or wood. These reading stones were similar to hand-held magnifying lenses of todayMost historians believe that the first form of eyeglasses was produced in Italy by monks or craftsmen in Pisa (or perhaps Venice) around 1285-1289. These magnifying lenses for reading were shaped like two small magnifying glasses and set into bone, metal, or leather mountings that could be balanced on the bridge of nose.The first known artistic representation of the use of eyeglasses was Tommaso da Modena’s painting in 1352. His painting depicts monks reading and writing manuscripts. One monk uses a magnifying glass, but another wears glasses perched on his nose.The first eyeglasses can only be used to rectify hyperopia and presbyopia. And those eyeglasses for myopia appeared much later, sometime in the early 1400’s.Glasses HistoryThe first vision aid, called a reading stone, was invented around 1000 AD. The reading stone was a glass sphere that was laid on top of the reading material to magnify the letters. The first wearable eye glasses were invented around 1284 in Italy. It is thought that Salvino D’Armate was their inventor.

People have been using vision-correcting tools of some kind since as early as 60 A.D.Roman philosopher Seneca from that time used a glass globe of water to magnify the text he was reading, and Emperor Nero couldn’t see gladiator fights very well without his magnifying emerald. We’re glad we don’t have to rely on these kinds of imprecise and antiquated tools, but it’s fascinating to see how vision correction has gotten to where it is now, and the long, winding road it took to get there.Corrective Lenses Over the CenturiesIt would take almost a thousand years after those emeralds and globes of water until lenses would actually be manufactured to help with reading. It was monks in 10th century Europe who came up with the idea to polish domes of transparent quartz, which they called “reading stones.” They needed these to be able to see clearly enough to do the fine details in their illuminated calligraphy.After that, it took another couple of centuries before anyone had the idea to put a couple of reading stones into frames so that they would be wearable. A Florentian named Salvino D’Armati was credited with the invention of spectacles, but scholars are skeptical that this man actually existed, so the identity of the real inventor is unknown.
