When Were Glasses Invented?
Have you ever wondered when were glasses invented and who had the genius idea of creating them? This article is about the history of glasses, who invented them, and how they slowly developed into what they are now.
When the first were glasses invented – the early stages
Optical devices were in use back in 1000 A.D. In Ancient Rome, Seneca is believed to have read “all the books of Rome” using a glass globe of water as a magnifier, while monks in the Middle Ages were said to use glass spheres as magnifying glasses to read.
Sources are unclear on when glasses were developed and by whom; some credit the invention to Salvino D’Armate; his epitaph in the Santa Maria Maggiore church in Florence referred to him as the “inventor of spectacles.”
Others, on the other hand, credit the invention to Friar Alessandro Della Spina of Pisa. While it seems evident that glasses were invented somewhere in Italy, it’s hard to name the exact inventor.
The first-ever glass frames were created in Venice. The city is well-known for welcoming the most talented glass blowers. Frames were made of bone, leather, or metal, and these glasses were used to magnify words and help during reading.
The first evidence for eyeglasses is Tommaso da Modena’s 1352 portrait of cardinal Hugh de Provence reading in a scriptorium. While it would have been impossible for the cardinal to use eyeglasses (he lived way before glasses were invented), the painting proves that in the mid 13hudreds, glasses were already ordinary and used by cardinals.
Who invented eyeglasses, and how were glasses made?
The invention of printing and the distribution of more and more books led to a higher demand for prescription glasses: people needed better vision and help to read. The most significant developments around glasses started happening during the 17th century. Most importantly, glasses slowly transitioned from just magnifying words to correcting vision.
Here are the most significant steps in the development of glasses:
In the 1600s: concave lenses are invented to improve distance vision.
1727: temples finally make their appearance thanks to optician Edward Scarlett, making glasses more structured and stable on the face
1784: Benjamin Franklin invents the bifocals dividing lenses into two zones: one for distance vision, one for near vision
1827: Thomas Young discovers astigmatism and later invents cylindrical lenses that are now used to correct it
1959: Bernard Maitenaz invents progressive lenses, giving up on the line that used to divide bifocal lenses
1950-60: hard plastic contact lenses are being used and become more common
During the 19th & 20th centuries, the development of eyewear continues, and glasses are constantly redesigned with thinner lenses and different frame designs.
Glasses today are made with lightweight materials, such as plastic or metal, to ensure comfort and durability; this was not the case many years ago, as lenses were made with heavy glass, and frames were made of leather or bone.
DID YOU KNOW?
Many of the earliest known uses of corrective lenses were in Italy.
When did eyeglasses become common?
At the beginning of the 19th century, glasses were still handcrafted and not accessible to everyone. Not only were they scarcely produced, but because of their handmade nature, they were costly and only available to wealthy families.
However, the industrial revolution was just around the corner, making it much simpler for working men and women to get the necessary eye correction. Thanks to the mass manufacture of both frames and lenses, these became more available, giving more people a chance to have better vision and good eye health.
