Who Invented Eyeglasses and When?

Nobody knows the exact inventor. Wearable eyeglasses were created by unnamed glassmakers in northern Italy around 1286 to 1290. The breakthrough is documented by a 1306 sermon from friar Giordano da Pisa, who said the craft of making spectacles was “not yet twenty years old.” So when people ask who invented eyeglasses, the honest answer is: medieval Italian artisans, not a single person.

Few inventions changed daily life as profoundly as spectacles, yet the question of who invented eyeglasses has no tidy, one-name answer. Part of the reason is that early craftsmen rarely signed or recorded their work, and the technique spread by imitation from one workshop to the next. What we do know points clearly to late-13th-century Italy, and to the skilled glassmakers whose craft made reading possible for millions.

So, Who Invented Eyeglasses?

The question of who invented eyeglasses has intrigued historians for centuries. The evidence points not to a lone genius but to a community of Italian craftsmen working with newly refined glass. According to Encyclopaedia Britannica, eyeglasses first appeared in Italy, and the earliest known portrait showing them dates to 1352.

The Role of Italian Glassmakers

Italy in the 1200s was the world capital of fine glass, and its artisans had learned to grind clear, convex lenses, the essential ingredient for wearable spectacles. The groundwork was laid centuries earlier by the Arab scholar Ibn al-Haytham, whose Book of Optics was translated into Latin around 1240 and widely read in European monasteries, where it inspired the first practical lenses. In 1268, the English friar Roger Bacon made the earliest recorded comment on using lenses for optical purposes.

Pisa and Venice

Two centres stand out: the region around Pisa, and the glassmaking island of Murano in Venice. The Italians even gave us the word lens, because the finely ground glass disks resembled lentil beans.

Guarding the Craft

Venetian glassmakers guarded their methods so closely that spectacle-making was regulated by guild rules within decades, one of the earliest examples of quality control in the history of eyewear.

When Were Eyeglasses Invented?

The timeline below shows when eyeglasses were invented and how the craft developed:

Year / Era	Milestone
c. 1286	First wearable eyeglasses made in northern Italy
1306	Friar Giordano da Pisa records the invention as under 20 years old
1352	First portrait depicting eyeglasses is painted
15th c.	Concave lenses correct short-sightedness
1784	Benjamin Franklin invents bifocals

What the First Eyeglasses Looked Like

The earliest spectacles, known as “rivet glasses,” were simple but ingenious:

• Two convex lenses, ground from glass or quartz
• Frames of wood, bone or metal, joined by a central rivet
• No arms: they balanced on the bridge of the nose
• For farsightedness: helping ageing readers, monks and scholars

Early lenses were sometimes ground from quartz or beryl rather than glass, and a finished pair was a costly luxury owned mainly by scholars and the wealthy. Only as glassmaking improved did spectacles slowly become affordable to a wider public.

How They Were Worn

Because there were no side-arms until around 1727, wearers had to hold the frames in place or perch them carefully. Arms that hook over the ears were a much later refinement.

The Salvino d’Armati Question

For centuries, a Florentine named Salvino d’Armati was named as the inventor. Modern historians, however, treat this as a legend based on an unreliable later inscription. As the detailed history of eyewear on Wikipedia confirms, no single individual can be verified, reinforcing that who invented eyeglasses is best answered as “medieval Italian glassmakers, collectively.”

How Eyeglasses Evolved After the Invention

Once invented, spectacles spread quickly and improved steadily:

→ The printing press (1440s) multiplied demand for reading glasses
→ Concave lenses corrected short-sightedness by the 15th century
→ Side-arms over the ears arrived around 1727
→ Contact lenses and precision lenses transformed eyewear in the modern era

From Italy to India

That long evolution eventually reached India. In 1877, Lawrence & Mayo opened its first showroom in Calcutta, bringing European precision opticianry to the subcontinent, a story told across its 149-year legacy.

Did you know? Lawrence & Mayo became the first retailer to introduce contact lenses and computerised eye-testing in India, pioneering firsts woven through the brand’s heritage.

Who Invented Eyeglasses: The Verdict

So, who invented eyeglasses? The most accurate answer is that they were invented by unnamed Italian glassmakers around 1286, refined over centuries into the precise, elegant frames we wear today. That same pursuit of clear, beautiful vision continues at the Lawrence & Mayo Boutique, where seven centuries of craft meet modern luxury eyewear.

Frequently Asked Questions

Who invented eyeglasses?

Eyeglasses were invented by unnamed glassmakers in northern Italy in the late 13th century, around 1286. No single person is documented as the inventor.

When were eyeglasses invented?

Around 1286 to 1290. A 1306 sermon by friar Giordano da Pisa recorded that the craft of making spectacles was less than twenty years old at the time.

Where were eyeglasses first made?

In northern Italy, with the region around Pisa and the glassmaking centre of Venice among the earliest hubs of production.

What did people use before eyeglasses?

From around 1000 AD, people used reading stones, polished glass spheres laid directly on the page to magnify text.

Did Benjamin Franklin invent eyeglasses?

No. Benjamin Franklin invented bifocals in 1784, but eyeglasses themselves already existed nearly 500 years earlier in 13th-century Italy.
