The Historical Journey Behind the Invention of Glasses

goodfair.xyz – Glasses are a very useful seeing aid if you have vision deficiencies. The discovery of glasses has a long history, until finally this tool developed rapidly and became part of world fashion trends. Especially in old age, where their ability to see is no longer as good as when they were young, glasses have a big impact on their lives. Whether it’s for reading, watching television, etc. So, who invented the first glasses and how were glasses discovered? In fact, it is not known who invented glasses first . However, the tragedy of Seneca in the Roman period which took place around the 4th century BC (BC) is said to be the era of the first glasses in the world. At that time, the Romans used glass balls filled with water as magnifying glasses for reading.

However, most historians believe that the first form of glasses was produced in Italy by monks or craftsmen in Pisa (or perhaps Venice) around 1285 to 1289. These reading magnifying lenses are shaped like two small magnifying glasses and are mounted on a bone, metal, or skin support that can be balanced on the bridge of the nose. The first known artistic representation of the use of glasses is a painting by Tommaso da Modena in 1352.

His paintings depict monks reading and writing manuscripts. One monk uses a magnifying glass, but another has glasses perched on his nose. Reported by Glasses History , Thursday (25/3/2021) the first glasses were known to only be used to correct hyperopia and presbyopia. And minus glasses for myopia appeared much later, namely around the early 1400s. It is believed that, before the invention of glasses , the first visual aid, called a ‘reading stone’ was discovered around 1000 AD. History records that this reading stone is a glass ball that is placed on top of reading material to enlarge the letters.

Then, the first wearable glasses were invented around 1284 in Italy. It is thought that Salvino D’Armate was the inventor of this viewing aid. Salvino D’Armate is predicted to be one of the figures most often associated with the invention of the first wearable glasses around 1284 However, glasses as we know them today were invented in 1929 by Sam Foster. He made them using polarizing filters and sold them to the public at Atlantic City Woolworths. In the 17th century people recognized the principles of concave and convex lenses.

Glasses can be manufactured with a single lens that corrects distance or near vision or can be manufactured with multifocal lenses that correct both distance and reading. Concave glass is used to correct nearsightedness, so that light rays can be distorted. Convex lenses are used to help correct nearsightedness, so that the light rays converge. The cylindrical lens used to correct astigmatism was invented by Sir George Airy in 1825. Meanwhile, bifocal lenses can be used to treat nearsightedness and presbyopia with the lower part for viewing close objects such as for reading, first created by Benjamin Franklin in 1784.

The first eyeglass frames were made by Spanish craftsmen in the 1600s. They attached silk ribbons or string to the frame and looped them around the user’s ears. Then, in 1730, Optometrist Edward Scarlett designed rigid temples that sat over the wearer’s ears. Glass, plastic or polycarbonate is one of the lens materials for glasses. Glass is the original material for glasses because it has good optical clarity, but glass lenses can be very heavy in stronger prescriptions. Plastic lenses are much lighter than glass but scratch easily. The lightest and thinnest lens material for glasses is polycarbonate, also called CR-39. Glasses have become one of the inventions that changed the world and had a huge impact on life. Lenses must be prescribed by an ophthalmologist or optometrist and made by an optician.
