Eyeglasses became a common, everyday item in the second half of the 1800s, when industrial mass production made them affordable for ordinary people. Before that, they existed for roughly 600 years as expensive, handcrafted tools available mainly to the wealthy, clergy, and scholars. The transition from luxury to necessity happened gradually, driven by rising literacy, factory production, and the professionalization of eye care.
From Monks to Magnifying Lenses: The 1200s
Italian monks crafted the first semi-shaped ground lenses in the 13th century. These early devices worked like magnifying glasses, held up to the eyes or balanced on the nose, and were used exclusively to help farsighted people read. The glassworks in Murano, Italy was the only factory at the time capable of manufacturing the soft glass needed for lenses, which kept production limited and prices high. For centuries, owning a pair of spectacles signaled wealth and learning.
The Printing Press Changed Everything
The invention of the printing press in the 1450s was the first major force pushing eyeglasses toward widespread use. As books became cheaper and more available, literacy spread beyond monasteries and universities. More readers meant more people discovering they couldn’t see well up close, and demand for reading glasses grew steadily. Still, spectacles remained handmade and expensive, so this demand mostly benefited the growing merchant and professional classes rather than the general population.
The Frame Problem
One reason glasses stayed niche for so long was a basic design flaw: they didn’t stay on your face. For centuries, spectacles either balanced on the nose (pince-nez style) or were held up by hand. Some users tied threads to the frames and looped them behind the head or attached them to small weights draped over the ears.
Around 1720, side bars (the arms of modern glasses) appeared for the first time. Early versions pressed against the temples or rested on top of the powdered wigs that were fashionable at the time. When wigs fell out of style, designers adapted the arms to hook behind the ears or fold behind the head. The modern curved earpiece didn’t arrive until around 1850. This seemingly small innovation made glasses practical for active, everyday wear rather than just sitting down to read.
Mass Production in the 1800s
The real turning point came with industrialization. The American Optical Company, founded in the 1830s, illustrates the scale of change. By 1852, the company produced nearly 15,000 pairs of spectacles in silver, steel, and gold. In 1874, it offered just five styles and sizes. By 1887, that number had exploded to 1.5 million pairs produced annually with a workforce of 400. Five years later, American Optical was the largest optical company in the world, turning out two million pairs of spectacles and three million pairs of lenses with 800 employees.
The effect on pricing was dramatic. Handmade eyeglasses that previously only the wealthy could afford were now being mass produced at costs ordinary families could manage. Steel-framed spectacles became extremely popular by the 1860s, praised for being both light and durable. Other optical manufacturers followed the same trajectory. Erkers Eyecare, which opened in St. Louis in 1879, operated the first optical lens factory west of the Mississippi, a sign that the industry was spreading across the country rather than staying concentrated in a few workshops.
How Common Were Glasses by 1900?
By the late Victorian era, glasses were unmistakably mainstream. In 1871, a British periodical marveled at the sheer number of spectacle wearers and wondered how “former generations managed to get on without them.” A decade later, one optician calculated a ninefold increase in spectacle sales over just five years. Medical texts from the second half of the 1800s record boys as young as seven, girls as young as eight, and adults well into their 80s wearing visual aids. By 1900, optical publications were debating which frame styles worked best for people who wore their glasses constantly, rather than just occasionally for reading. That shift in language tells the story: glasses had gone from an occasional tool to something people put on in the morning and kept on all day.
Professional Eye Care Seals the Deal
The final piece was making sure people could get properly fitted. For most of history, buying glasses meant picking a pair off a peddler’s tray and hoping for the best. That began to change at the turn of the 20th century. New York attempted to pass the first optometry law in 1897, and Minnesota succeeded in 1901, becoming the first state to require licensure for eye exams. These laws established that fitting someone for glasses was a professional skill, not guesswork.
The profession expanded steadily through the 1900s. By midcentury, optometrists were pushing for broader authority to examine and diagnose eye conditions, not just prescribe lenses. Pennsylvania’s optometric association passed a resolution in 1958 to allow unrestricted eye examinations. Rhode Island became the first state to authorize optometrists to use diagnostic eye drops in 1971. By 1987, nearly every state had passed similar laws. This professionalization meant that by the mid-20th century, getting your eyes checked and picking up a pair of glasses was a routine experience available in virtually every American town.
The Short Answer
Eyeglasses existed from the 1280s but remained rare and expensive for roughly 500 years. The printing press boosted demand starting in the 1450s, and practical frame designs arrived in the 1700s. The real inflection point was the industrial era of the mid-to-late 1800s, when mass production dropped prices low enough for the average person. By the 1870s and 1880s, wearing glasses was ordinary. By 1900, they were so ubiquitous that commentators were already taking them for granted.
