A Brief History of Eyeglasses: How This Simple Invention Has Helped Us See for Centuries
It’s hard to believe eyeglasses were invented centuries ago when eye infections were the norm. They were invented way back in 1284 by Salvino D’Armate, who happened to be an Italian bishop.
Nowadays, people would argue that this invention is one of the most important inventions in all of human history because it paved the way for further discoveries in both scientific research and ancient and modern artworks.
We live in an era where information is at our fingertips, and we can easily access it no matter what time of day or night it is. The evolution of the computer and mobile devices nowadays has made our lives much easier. So why would eyeglasses have such an essential role in this modern world?
Eyeglasses changed human perception, improved vision, and allowed people to see well enough to do things like reading books and watching movies. This invention also laid the groundwork for further scientific discoveries.
The history of eyeglasses is full of interesting and amusing stories. Many people know that Leonardo da Vinci designed a rudimentary pair in the 15th century. They were the first ever to use lenses, which made them obsolete by the 20th century. But have you ever heard about how this invention has helped us see for centuries?
How Did Eyeglasses Work Back Then?
Eyeglasses were born from an ancient form of telescope known as a “perspective glass.” It seems as though these glasses weren’t as beneficial for mankind until almost 400 years later when they became prevalent with technological advancements in Europe during the 17th century.
Eventually, eyeglasses came in two different styles; the pince-nez and the lens. The pince-nez was the type of glasses you might have seen a professor wear. It consisted of two hinged lenses attached to a small bar connected to a nose rest. This is also called “French glasses” since it originated in France during the 1730s and 1740s.
Despite being less fashionable, the lens glasses were more relaxed and easier to wear than the pince-nez. They could correct vision problems such as nearsightedness, farsightedness, and astigmatism by placing lenses in front of the user’s eye sockets.

Evolution of Eyeglasses
Initially, glasses had no frames, but they soon became fashionable objects in their own right. The first frames were a combination of silver and gold, which were immensely popular amongst royals. Later on, the glasses became more affordable and could be found on the faces of both men and women.
The invention of eyeglasses since the 14th century has helped people with vision problems see clearly; however, it wasn’t until the 18th century that eyeglasses became a symbol of intelligence and fashion. Paris was one of the first places where spectacles were very popular.
During the 19th century, glasses were considered a sign of prestige and wealth. Eyeglasses only became more popular during the 20th century, when they became even more affordable. Today’s glasses are much stronger and can be made with plastic or metal frames. They are also equipped with spring-loaded hinges to make them easier to wear.
The Invention Of Glasses
The oldest glasses are found in Venice, Italy. They were discovered on the San Giovanni d’Asso church site and date back to 1268. They were not spectacles, however, but magnifying glasses. While they did allow a person to see objects more clearly, they were not as useful for everyday wear as modern glasses. Glasses would not be invented for another century.
The invention of eyeglasses was first documented in Italy in 1280 by an anonymous author. He describes windsor eyeglasses history with lenses for both eyes and long and short-sightedness problems. This is the first known documentation of both corrective and varifocal lenses.
During the next two centuries, the technology surrounding glasses became more advanced. A new type of lens was invented in the mid-1400s, which improved the lens made in 1280. Still, it wasn’t until the 15th century that lenses were created that could correct for both near- and far-sightedness.
It wasn’t until the 16th century that spectacle frames began to be used for glasses. This advancement allowed more people to wear glasses because it made them easier and more comfortable. And, during the 17th century, people started wearing glasses in their daily lives.
The Invention Of Reading Glasses & How They Helped People Read
Many people who wear glasses say they can’t read without their glasses. Glasses were indeed developed in part to help people see better. But they were also created to help people read better.
A French inventor named Antoine Fontana is often credited with inventing glasses with clear lenses for reading in 1368. He is often referred to as the “Father of Spectacles.”
But that’s not exactly true. In reality, he created a new style of spectacles called “closer glasses.” They were so named because they allowed the wearer to bring things closer. He developed them for his use because he was going blind in his left eye, and he needed visual aids to make this helpful eye again.
Nearly 75 years later (1444), the first document was written that officially described these glasses. Fontana’s glasses were the second type of reading glasses ever made since the first type was invented in France in 1329. These first reading glasses were heavy and thick. This style of glass was also called “cathinol.”
The next significant advance in eyeglasses came with the invention of the bifocal spectacles by Dr. John Keeler at the Ohio State University in 1850. The bifocal lens was created for people who needed to read up close but wanted to see fine details from a distance. A more popular style of reading glasses, which came along at about this same time, were called “half-rim” and “falsetto.”
The Invention Of Eyeglasses
We all know that glasses protect our eyes from the sun’s rays. But this idea wasn’t invented until 1896 when a German-American inventor named Otto Wichterle created a new type of eyeglass lens made of cellulose acetate as from windsor eyeglasses history. And a few decades later, Eyeglasses were invented when Sam Foster, owner of the largest Eyeglasses factory in the world, attached lenses to delicate wire frames.
Since then, Eyeglasses have become popular all over the world. They’re not just for people who need glasses to see; they are now an accessory for anyone who wants protection from the sun’s harmful rays and appearance enhancement. The Eyeglasses industry grew from $50 million to over $4.5 billion in just the last ten years.

The Invention Of Glasses With More Than One Lens
Another essential invention in eyeglasses came a short time later when glasses with more than one lens were invented. The idea of having two or three lenses was first discovered by an Italian (Cornaro) mathematician named Santorio Santorio between 1557 and 1571 as from antique eyeglasses history.
It is believed that he took the idea from a manuscript of Leonardo da Vinci’s “Codex Atlanticus,” which contains drawings of glasses with two or three lenses. It is widely accepted that he lived in Florence, Italy, during the late 1500s and early 1600s.
He experimented with this new invention and determined the best distance between lenses and eye by performing experiments on himself. He discovered that the ideal distance was five or six inches and that this configuration was most convenient for people who worked at tables or desks.
The first written description of bifocals was discovered in 1590, but there is some debate as to whether it was invented before Santorio Santorio’s discovery. The first recorded use of bifocals was in 1609 when a German inventor named Johannes Gutenberg (who invented the printing press) used them to read from his printing machine as from antique eyeglasses history.
Nearly 40 years later, James Ayscough discovered that bifocals could be made lighter if the top lens was thinner. He also created a lens attached to a pair of spectacles to switch from one to the other easily. This type of spectacle frame is still in use today.
In 1657, a Dutchman named Hans Lippershey invented the first spectacle frame with a hinge that allowed the lenses to be flipped up when not needed. It wasn’t long after that when Robert Hooke invented a mount for spectacles to be worn on the forehead instead of on either side of the nose and ears.
The Invention Of Glasses With Adjustable Lenses
It was the early 1900s when people started wearing glasses made of plastic. And it was in the 1920s, that eyeglasses with adjustable lenses came into use. In 1925, John Lister Conley invented the three-point adjustable system for eyeglasses. It consisted of three metal screws with a metal frame around them and a hinge.
He developed these frames for better vision correction and different uses, such as astigmatism, myopia (nearsightedness), hypermetropia (far-sightedness), and presbyopia (age-related nearsightedness).
The Invention Of Eyeglasses With Removable Lenses
People have worn Eyeglasses since the early 1900s, but in the 1960s, a man named Dr. Herbert O. Yardley invented removable Eyeglasses that were commercially available. Yardley was born in New Jersey in 1934 and started working for Johnson & Johnson in 1956 as a developer of therapeutic eyewear.
In 1964, he developed a pair of Eyeglasses with cataracts (cloudy lens) that had replaceable lenses for people who needed them and patented his frames.
From first eyeglass lens history timeline, his company became the foundation for how we buy and wear Eyeglasses today, selling his idea to companies like Ray-Ban and Maui Jim (and later through heavy advertising campaigns).
The Invention Of Glasses With Contacts
From first eyeglass lens history timeline, the next significant invention in glasses was the development of contacts, invented in the 1950s and 1960s by a man named Edward Laskowski. He was interested in developing contact lenses because he had astigmatism and myopia.
Laskowski developed a method of attaching an insulating layer to his lenses, which allowed him to design clear lenses safe for contact lens wearers with cataracts, keratoconus (a form of corneal abrasion), and astigmatism. His contacts were first sold commercially in 1955 (by Kodak) and were the first contact lens product so widely available.
What Were The Most Important Inventions in Glasses?
Materials: Glass, Plastic, and Polymers.
People have been wearing glasses for centuries, but it was the 18th century when people started wearing glasses for cataracts made of glass. The Modern Age of Glasses was in the early 1900s when plastic contact lenses were invented, and eyeglasses with adjustable lenses came into use.
The Invention Of Glasses With Adjustable Lenses
The biggest technological advancement in glasses was the invention of adjustable lenses. The first commercially available glasses with adjustable lenses were called “De Kalb” frames, invented by Henry J. Gaisman and Louis Elfenbein in 1918.
Before this point, most people who needed glasses had to have their lenses replaced every time their prescription changed (which happened regularly). This new invention was a huge step forward, particularly for people who wore glasses every day or had progressive prescriptions.
The development of eyeglasses can be attributed to a few separate but similar inventions. It started around the 10 th century when spectacles were invented. Early glasses models used a double convex lens to correct vision. This was not very effective and could only be used by people sitting close to a book.
Another version of spectacles was invented in 1286, and this is where modern glasses come from. They were invented by Salvino D’Armate, an Italian mathematician who thought lenses would help him read better as from ful vue eyeglasses history. Spectacles are true wearable glasses, as it has two lenses that fit over both eyes.
Early eyeglasses were similar to spectacles. These glasses had a small convex lens for close vision and a round lens for distance vision.
They were the first to use lenses, the first pair of glasses was created in 1606 by Italian mathematician Giovanni Battista Della Puente, but it took until 1614 to be mass-produced. The first pair was made of pewter and cost 10 guilders (a huge sum).
The same year Henry IV of France also had a pair made, making them both extremely expensive. It was not until 1625 that spectacles became affordable for the middle classes.

The First Written Record of Eyeglasses
The first-ever written record of eyeglasses is from Italy in 1286. The location and name of the inventor have been lost to time. The text described glasses with two convex lenses to correct “migraines and myopia.”
The term myopia (nearsightedness) came from the Greek word “myops,” meaning close or nearsighted. A person with myopia can see things as if they were further away from them than they are. It is a common type of vision disorder.
Luxurious Fashionable Glasses
Italian engineer Salvino D’Armate invented the first pair of eyeglasses in 1286. Although he was not the first to make spectacles, it was the first to use two lenses with a metal frame. These glasses were expensive and only worn by rulers and popes.
During the Renaissance, people were fascinated by new technology, optics, and physics. They were obsessed with breaking down problems into simple mechanical actions, which eventually led to the invention of eyeglasses.
At first, they were just used by intellectuals to correct nearsightedness and other vision deficiencies, but they slowly became a fashion accessory. In the 1450s, reading glasses were invented in Italy.
These glasses had a single lens, but it would take around 200 years to become popular with the public as from ful vue eyeglasses history. In 1584 a spectacle lens was made that did not change the shape of the eye.
The French and English Glasses
Throughout the 1600s and 1700s, glasses became much more popular, they were considered essential for literacy and intellectuals, but they were still expensive and difficult to acquire. In 1752 Benjamin Franklin invented bifocals (also known as half-spectacles).
Half of the lenses are used to see far-away objects, while the other half can see things up close. In 1792 a British act was passed that said children between 5-13 had to go to school & required eyeglasses within 4 years of starting school. The first-ever written record of spectacles came from Italy in 1286. The location and name of the inventor have been lost to time.
The American Contacts
In 1938, American ophthalmologist Dr. William K Moor, an optometrist, developed Moor’s Contact-Lenses for diabetics, which were a practical alternative to insulin injections. It allowed them to see far better than before.
This invention inspired Alfred F Hoff to develop a set of contact lenses for treating glaucoma (an eye disease causing pressure inside the eye). This helped to improve the lives of millions. The invention of contact lenses was a major step in human advancement, and the history of contact lenses is an exciting story we can learn from.

The Polytetrafluoroethylene Contacts
In 1970, American Ray Shure developed an improved version of the silicone contact lens that could be worn for longer periods without washing or changing it.
This product is still used to this day, and there are many different kinds available, including those that are simply disposable.
The material covering the lens, called “polytetrafluoroethylene” (PTFE), resists staining and does not react with other chemicals in the skin or eyes. PTFE contacts are a top-rated product, and you will find many different kinds of these made.
The Contacts that Changed the World
In 1978, Johnson & Johnson introduced “Clear Care” contact lenses. These lenses were designed as an alternative to disposable lenses, and they were first used in the 1940s. Johnson & Johnson, who had popular brands such as baby foods, Benylin, and Tylenol, created a new type of contact lens called “blue,” designed to correct myopia (nearsightedness).
They also released soft-determined tinted contact lenses and improved them, making them less likely to scratch your eyes. The lenses were a big hit and became a prevalent form of contact lenses.
In the early 80s, Bausch & Lomb developed flat-lens “Dailies.” These were another big hit with consumers, but unfortunately, they were discontinued in the 90s when people started to prefer soft contact lenses over hard ones, which Bausch & Lomb did not release.
In 1994, British company Lasek introduced an inflatable soft lens for overnight use for people who have irregular eye requirements. This was an important invention that many people today take advantage of.
The Contacts that Were Used to Kill
In the 19th century, bifocal contact lenses were already used, but they were very costly and not yet popular. The first bifocal lens was made by French ophthalmologist Pierre Jules César Javal in 1838.
An Englishman named John Addison came up with a new idea: one half of a small lens would be covered in glass and used for close work, and the other half would be clear. He also invented putting these two together into one complete lens, which he called “Addison spectacles.”
In 1850, Englishman Howard Jones bought the patent for bifocal glasses, but instead of making the lenses for himself, he invented a new method. John Scott Russell soon bought his method, and the first commercially produced bifocal glasses were sold in 1872 from the eyeglasses history timeline.
The first-ever bifocal lens was made by an ophthalmologist named William K Moor in 1855. They were really expensive, around 90 pounds (50 pounds per eye).
The Contacts that Keep Us Safe
In the early 1990s, an American company introduced glasses that could correct a person’s vision shapes. Instead of using glasses, people could wear clear contacts and still see. However, this was not practical for people who had to wear glasses for work, such as police officers, who might drop them off after a shot or some other unfortunate event.
A simple solution would be to use two contact lenses for each eye, but it would mean more parts to lose and break, which would be fatal in some cases. A better idea was to use two contact lenses with a hinge between them so they can be adjusted to the way you see. This innovation is called “Walker-Lang,” invented by David Lang and Bruce Walker.
In 1968, these two brothers set up an optometric laboratory to supply bifocals and refracted glasses. They came up with using a hinge to switch from one lens to the other depending on what you want to see. In 1974, their company, “Combi Vision,” started producing “Walker-Lang” contacts for people with diabetes.
This invention is one of the most important in human history, and so many people dreamed of having this technology in their own eyes from the eyeglasses history timeline. Eventually, with the help of a team, they were able to create a licensed version for all people who need this kind of lens.

Eyeglasses have helped people see clearly because of the technological advancements in Europe during the 17th century. You might have seen a professor wearing pince-nez, which was popular during the 18th century, or lens glasses that are less fashionable but very practical since they can correct vision problems such as nearsightedness, farsightedness, and astigmatism.
