A Four-Eyed World: How Glasses Changed the Way We See

by David King Dunaway

An engaging and informative cultural history of glasses that explores their origins, stigmas, future in technology, and more.

Eyeglasses have become so commonplace we hardly think about them-unless we can't find them. Yet glasses have been controversial throughout history. Roger Bacon pioneered using lenses to see and then spent a decade in a medieval prison for advocating that he could “fix” God's creations by improving our eyesight. Even today, people take off their glasses before having their picture taken, despite how necessary they are.

A Four-Eyed How Glasses Changed the Way We See is the first book to investigate the experience of wearing glasses and contacts and their role in culture. David King Dunaway encourages readers to take a look at how they literally see the world through what they wear. He explores everything from the history of deficient eyesight and how glasses are made to portrayals of those who wear glasses in media, the stigma surrounding them, and the future of augmented and virtual reality glasses, highlighting how glasses have shaped, and continue to shape, who we are. Interwoven is Dunaway's own experience of spending a week without his glasses, which he has used since childhood, to see the world around him and his newfound appreciation for his visual aids.

This is the story of how we see the world and how our ability to see things has evolved, ultimately How have two cloudy, quarter-sized discs of crystal or glass originally riveted together become so essential to human existence? Shakespeare famously said eyes are windows to the soul, but what about people who see only by covering theirs with glasses? Readers will find out together through this fascinating and insightful cultural history of one of humanity's greatest inventions.

I love nonfiction books that take a deep dive into a relatively narrow topic, and I was excited to learn more about glasses. However, this book was ultimately a disappointment.

I really enjoyed the author's conversational writing style, but the book was disjointed and repetitive. It read like something from the slush pile that could be turned into something great, but lacked an editor's oversight. The author starts with the history of glasses, detailing the early inventions and the innovations that eventually led to today's high-tech specs. This was the strongest part. But then, he'd take on a different aspect of glasses-wearing, for example literary depictions, and then go back in time to Poe and Doyle and progress to present-day authors like J. K. Rowling. Then the next chapter would be film depictions. It would have been much stronger if all the relevant aspects of glasses were grouped together chronologically (rather than just chronologically within chapters).

I did enjoy the anecdote about Marie Antoinette affixing a side mirror to her fans (like the addition to some older specs) so she could see (eavesdrop?) without turning her head.

I was not a fan of the author's experiment of going a week without glasses, which he details by day and intersperses with the more general info. All glasses wearers (I refuse to use "glassers") and probably most people with good vision would be able to predict what he would encounter: he ran into furniture, spilled a lot of food and drinks, misplaced items, etc. I think it's pretty commonly known that when one sense is restricted, the others become sharper. However, it seemed to be a revelation to him that his hearing was enhanced during this time.

There are interesting tidbits here, but you do have to spend a lot of time unearthing them.

Billions of humans have shared the experience of wearing lenses to see better. Today, whether we see sharply or blurrily, in focus or out, most of us eventually come to view the world through corrective lenses because of aging. Although we make up about two-thirds of the US population, we don’t think of ourselves as a distinct community; there is no National Association of Glasses Wearers conference in Las Vegas. The dictionary lacks a word for those wearing lenses, so I’ll call us “glassers”: anyone who walks around, sometimes or always, with a lens between them and the world. (Hey, it’s better than “four-eyes.”)

Though the story of the inventor is a who-dun-it, the evolution of eyeglasses is clear: a painstakingly slow progression from discovering “burning stones” for starting fire and then “reading stones” for magnification; to quizzing glasses and monocles, single-lens vision aids on a string; to glasses on a stick, the lorgnette; to the day someone managed to hang two of those magnifiers before eyes—eyeglasses; followed by pairs for the nearsighted and astigmatic; to bifocals popularized by Ben Franklin and frames made comfortable with sidepieces; finally to our time, where machines carve lenses driven by sophisticated software: a visual pageantry.

I have been a glasser since the 5th grade so 40 years now and had a pleasant interlude of wearing soft contact lenses for only about 15 years until dry eyes prevented me from wearing them. This book is an interesting overview of the history of glasses mixed in with the author’s experiences with glasses and trying to live without glasses for an experiment. I can relate to all of it. I do remember one summer, home from college, I woke up and looked out the window to a lush backyard and a giant oak tree and sunlight and it looked like a Monet painting, so I have experimented with looking at things without glasses often and feeling it is a unique experience non-glassers could never had. As I age, my vision is worsening faster, so I do worry about the future, mainly about driving, so maybe self driven cares aren’t so bad.

I also work with families with young children and for a long time have advocated for more and more outdoors time; in a metro area with tons of parks there is opportunity, but most of the kids spend 2-3 hours a week outside, not what is recommended:

How much time outside is enough for kids? About two to three hours per day. For each weekly hour spent outside, there’s a 24 percent decline in myopia among children.

Some kids spend no time outside for myriad reasons. It is really scary. Now, I did spend plenty of time outside growing up, certainly at least 6 hours a day and still developed it, so it is not a preventive for everyone. But if I can help any child have better vision, I will breathe easier. I don’t hate glasses and was never one to lose them all the time and need others to find them; but as my vision worsens, it is scary and if we can help people prevent it, its worth it. Really interesting read!

Looking back over the 750 years humanity took to invent and improve a device to transcend our visual limitations is an amazing experience. The inventors of spectacles could not have dreamed that one day two-thirds of the world’s population would wear them, or that some of us would put on a boxy version plugged into a computer that lets them share someone else’s eyes, as if inside another’s head. In our time, glasses represent the future as much as the past, in augmented and virtual reality—all descended from shiny pebbles of beach sand.

With glasses, I saw the world’s sharp edges. Without them, a comforting vagueness settled in. Would I come to prefer this out-of-focus world? Something positive was here, if I could only grasp it. Could I live this way? Could there be a slow-seeing movement, like the advocacy for slow food, slow cities, and so on? My newly imperfect sight was a poor translation of my former sight—and as humorist James Thurber commented about translations, “my work loses something in the original.” Overhead somewhere, a woodpecker tapped a tree limb. I couldn’t see it. Yet, I could still tell a cat from a coyote, a woman from a hat. I missed, though, the mountains sharply cutting the horizon at sunset. I tried to imagine what it would feel like to never see the expression on the face of my best friend. To never mean it, when I tell someone, “You’re looking good.” To miss the gleam in my son’s eye after opening a present, or to watch the blush rise in my spouse’s cheeks at a naughty remark.

Today, more folks are wearing glasses earlier in life and for longer than ever; nearly half of young adults in the United States and Europe are nearsighted—double the percentage half a century ago. According to the National Eye Institute, European myopia has increased a whopping 66 percent in thirty years, from 1972. In the United States, 41.6 percent of African-Americans have this problem. Nature notes that sixty years ago, the percentage of Chinese youth who wore glasses was 10–20 percent; today it’s up to 90 percent.Unfortunately, 30 percent of the world’s children lack corrective lenses, according to the PBS documentary Sight.

Neither can genetics explain how, in Seoul, South Korea, an astounding 96.5 percent of nineteen-year-old men are shortsighted. As the Freakonomics podcast wrote, “If there’s a drastic change in disease prevalence, this cannot be explained by human genetics, because genetic make-up simply does not mutate at this rate.” Only gradually, using studies with identical twins and factoring in ethnicity and education levels, did scientists begin to make out a surprising pattern.

I know the expression that a book teaches you how to read it, but this seems to be particularly on the nose.

This is a book about eyeglasses, and thus about visual impingement in general. It blends the history and science of eyeglasses, cultural and sociological impressions about them, the business of their manufacture and sale, and personal stories about them. It closes with discussions of what the future might bring for eyeglasses (augmented reality and similar).

The history is fluffy but inoffensive. The cultural survey of looking at eyeglasses in media sounds tedious but ends up interesting. While there are plenty of well-recognized examples, there are some incredibly weird implementations of eyeglasses as a sort of metaphor or magic that have come up, frequently by otherwise recognizable authors in their less recognizable works. Here we also have the strangest of historical takes. The sections on the discrimination that glasses-wearers face is in equal parts surprising and dull. On one hand, I did not understand the degree that anti-glasses sentiment was still globally prevalent. On the other, it is repetitive, and does not justify a man-on-the-street segment.

The business and futurism sections are fine: worth their own books. The author takes a neutral stance on both, which is worth the read for its novelty if nothing else. The stand out section is the sociological ones, particularly those around eugenics. I think that the author is too quick to dismiss most negative views as sort of lingering religious prejudice, so when the eugenics section comes in with its whole other take on why glasses are morally incorrect, it makes for good reading. If nothing else, it becomes some talking points for when you are arguing with your Dark Enlightenment loving brother-in-law.

The ‘wait, what?’ part of the book is where the author includes an experiment in his going without his eyeglasses for a week. As he has a strong correction, this impacts his life a lot. This attempt to go all A. J. Jacobs is both maddening and uninteresting. We know – or you should be able to guess – what happens and what the revelations are. It is both too much (if I wrote a book on depression where I quit my SSRIs, it would both be a lousy book and what would I even be making as a point?) and too little (there is something there about disability and accommodation, and what we do not think about in our social structure, but everything here is one-note).

It is not the book that I expected. In specific, it is much lighter and observational. It starts off slow, but I warmed to it in the end.

My thanks to the author, David King Dunaway, for writing the book, and to the publisher, Bloomsbury Academic, for making the ARC available to me.

I was surprised at how engaging this book was—surprised because I had never given much thought to the wearing of eyeglasses, beyond their being a nuisance and necessary burden to bear, especially as I grow older. But it turns out that everyday objects one takes for granted, such as eyeglasses, can make for a fascinating read.
The book begins with the history of assisted vision, emphasizing the importance of sight as the dominant human sense and the long struggle to improve it. It covers the discovery of glass 5000 years ago by the Phoenicians and the early use of lenses to create fire and make "reading stones" or magnifiers. The work of the thirteenth-century scholar, Robert Bacon, who was imprisoned and exiled for his scientific approach and the study of optics, was particularly compelling.
Subsequent chapters cover societal views and prejudices against wearers of glasses, from the risk of the charge of heresy in the thirteenth century to chilling views of a 20th-century eugenicist advocating the sterilization of near-sighted children. They cover glasses in literature, glasses in the world of fashion and Hollywood, the current optics industry, and finally glasses of the future, including virtual and augmented reality glasses.
Throughout all this, the author seamlessly weaves in his own memoir of growing up severely nearsighted and the difficulties that entailed, from enduring severe bullying as a child to a hair-raising tale of escaping a house fire without being able to see. He also relates a more recent personal experiment: going for a week without his glasses, which results in minor injuries and much reflection on how clearer vision contributes to his life. I was terrified when he attempted to drive without glasses and relieved when he quickly reversed course. The chapters are cleverly structured around the days of that week.
It was this mixture of personal narrative and an in-depth look at multiple aspects of glasses that made the book so entertaining to me. Now, when I put on my glasses, I do so with much more thought and appreciation.

A history of glasses - from the church's refusal to accept this visual aid (shocker) to Smart glasses and beyond.

Overall, pretty good. Interesting and almost conversational in its writing. It felt like it was lacking something though. What seemed like an interesting concept, a week without glasses, was pretty uneventful and didn't include anything I wouldn't expect (can't see, spilled food, stubbed toes).

**I received my copy from Netgalley.

Interesting book that’s written in easy to read writing/tone. I liked the dividing up between fact & experience, though as someone almost as short sighted, it did make me wince to read his diary.

Personally, I’d have liked the author to have included even more of what it’s like for glasses wearers in other countries, as I feel I’d have related to it even more.

Thanks to the author, publishers & NetGalley for access to this ARC, in return for my review.

A Four Eyed World by David King Dunaway is a fascinating cultural history that explores how eyeglasses have shaped both human vision and social perception.

The book blends historical insight with personal reflection, examining everything from early lens innovation to modern attitudes and emerging technologies like AR and VR.

Overall, it’s an engaging and thought provoking read for anyone interested in history, culture, and the everyday tools that quietly shape our lives.

"A Four-Eyed World" was somewhat of a disappointment:
I really enjoyed the first chapter on the history of glasses, but after that the author somewhat lost me.

The "experiment" of going without glasses was just nonsensical to me (I can't tell a pole from a person without my glasses), which is why I skipped these chapters, which seemed to consist mostly of personal anecdotes.

The other fact-based chapters were okay, but they also didn't really seem all that objective and / or did not really add any new information.

Reading this book is like spending time with an engaging and nerdy friend, which is something that I like. I did not anticipate enjoying the book so much. I have worn glasses since I was 8 y/o and just thought of it as a straightforward thing - like a shirt. I especially liked the chapter on why glasses cost so much. This book is an unexpected pleasure. Don't let the topic turn you away.
