What Percent of Americans Wear Glasses?

Roughly six in ten American adults wear eyeglasses, making corrective lenses one of the most common medical devices in the country. When you add contact lenses into the mix, the share climbs even higher. But the single-number answer obscures a lot of variation by age, race, income, and whether people who need correction actually have it. The gap between how many Americans have impaired vision and how many own a pair of glasses is itself one of the more telling public-health stories in the data.

How Common Are Refractive Errors

The reason so many Americans wear glasses is that refractive errors are extraordinarily common. Myopia, or nearsightedness, is the one most people think of first. A comparison of national survey data from the early 1970s to the early 2000s found that myopia prevalence among Americans aged 12 to 54 jumped from about 25% to roughly 42%, a striking increase over just three decades.¹ That rise showed up across racial groups and at every level of severity, from mild to high myopia.

Myopia is only part of the picture. Astigmatism, where the cornea or lens has an irregular curve that blurs vision at all distances, is at least as widespread. A systematic review of global data estimated that about 40% of adults have some degree of astigmatism, with prevalence climbing steeply after age 70.² Add in hyperopia (farsightedness) and presbyopia, the age-related loss of close-up focus that hits most people in their forties, and you have a population where the majority eventually need some form of optical correction. An analysis of national exam data found that just over half of all participants had a refractive error correctable to good acuity with the right prescription.³

Glasses Use Among Children and Teenagers

Kids wear glasses at lower rates than adults, but the numbers climb fast through childhood. National survey data from 2019 found that about a quarter of children aged 2 to 17 wore glasses or contact lenses. Among the youngest group, ages 2 to 5, the rate was only about 3% for both boys and girls. By the time kids reached the 6-to-11 bracket, roughly 20% of boys and 26% of girls were wearing corrective lenses. Among teenagers aged 12 to 17, nearly half of girls and about 35% of boys wore glasses or contacts.⁴

The sex difference among older children stands out. Girls in the 12-to-17 age group were substantially more likely to wear corrective lenses than boys of the same age, which likely reflects a combination of earlier onset of myopia in girls and higher rates of seeking vision care. Whatever the cause, by high school age girls are wearing glasses or contacts at rates that approach adult levels.

These childhood rates matter because myopia that starts early tends to progress. A child who is mildly nearsighted at age eight may need progressively stronger prescriptions through adolescence. For parents keeping track, the trajectory through school years is where most vision correction stories begin.

The Gap Between Needing Glasses and Having Them

One of the less visible aspects of glasses statistics is the number of Americans who need corrective lenses but do not have them, or who wear an outdated prescription that does not actually restore their vision. A national analysis estimated that about 14 million people aged 12 and older had visual impairment defined as distance acuity of 20/50 or worse. Of those, more than 11 million could see well with proper corrective lenses but simply did not have them.⁵ In other words, the vast majority of visually impaired Americans do not have an uncorrectable eye disease. They have a fixable optical problem and no fix in hand.

That gap is not random. Among people with a correctable refractive error, nearly 12% were inadequately corrected, meaning their glasses or contacts did not bring their vision to a functional level. The odds of being undercorrected were significantly higher for Mexican Americans and non-Hispanic Black individuals compared to non-Hispanic white individuals, and the disparity was greatest among teenagers aged 12 to 19.³ Low household income, less education, and lack of health insurance also predicted worse correction in adults.

Why Cost Is the Biggest Barrier

The most straightforward reason people go without glasses is cost. Eyeglasses are one of those peculiar medical necessities that many insurance plans either do not cover or cover poorly. Vision benefits are separate from medical insurance for most working-age adults, and Medicaid coverage for adult vision care varies dramatically by state.

Research on Medicaid adult vision benefits offers a clear window into what happens when cost barriers drop. When states added vision coverage to their Medicaid programs, beneficiaries were about 5 percentage points less likely to say they needed but could not afford glasses or contacts, and about 4 percentage points more likely to have seen an eye doctor in the past year.⁶ The coverage also reduced functional limitations from poor vision. Those effects are modest in percentage-point terms, but across a population of millions of low-income adults, they represent a lot of people who can now read signs, drive safely, and work effectively.

Affordability gaps also shifted over time and across groups. Between 1999 and 2008, the percentage of people reporting that they could not afford eyeglasses when they needed them increased among both non-Hispanic white and Hispanic populations. By 2008, about 27% of Hispanic Americans reported being unable to afford needed glasses, compared to roughly 16% of non-Hispanic white Americans and 15% of non-Hispanic Black Americans.⁷ People with the lowest incomes were consistently the most likely to report affordability problems, and this gap persisted across the entire decade of data.

Why Myopia Keeps Rising

The jump in myopia prevalence from about 25% to 42% over three decades is one of the most discussed trends in eye health.¹ Genetics alone cannot explain a shift that fast. Something about how Americans live has changed, and the usual suspects are near-work activities like reading and screens, along with less time spent outdoors.

The screen-time angle gets the most media attention, and the research is more nuanced than headlines suggest. A dose-response meta-analysis found some association between digital screen time and myopia risk, but the authors cautioned that myopia was already prevalent in many regions before digital devices became widespread, and that simply swapping screen time for other close-up activities like reading may not help much. The more promising approach, according to the evidence, is reducing all near-work activities while increasing time spent outdoors.⁸

Another meta-analysis reached a similar conclusion, noting that simply limiting screen time may have little effect on preventing myopia in children and adolescents, while actively promoting outdoor activity during daylight hours could delay onset and slow progression.⁹ A separate study that tracked children through pandemic lockdowns and the period afterward found no statistically significant link between daily screen time, outdoor time, or screen-time breaks and the rate of myopic progression in either period.¹⁰

The takeaway for parents is counterintuitive. The problem is probably not the screen specifically but the broader pattern of spending nearly all waking hours focused on things within arm’s reach instead of looking at distant objects in natural light. Outdoor time may be protective not because kids are “resting their eyes” but because bright daylight triggers biochemical processes in the eye that help regulate its growth. The evidence on exactly how much outdoor time helps, and whether it can reverse progression already underway, is still being worked out.

Alternatives to Glasses

Not everyone who needs vision correction wears glasses. Contact lenses account for a significant share of the correction market, especially among younger adults and teenagers. Refractive surgery, including LASIK and its variants, has been available since the 1990s and has freed millions of people from daily corrective wear, though uptake levels off after middle age because presbyopia eventually catches up and reading glasses become necessary again regardless.

For older adults, cataract surgery has increasingly become a vision-correction event rather than purely a disease treatment. Modern refractive cataract surgery can implant intraocular lenses designed to reduce or eliminate dependence on glasses at multiple distances. A comparison of two trifocal intraocular lens designs found significant differences in how many patients achieved spectacle independence for intermediate-distance vision, depending on the lens used.¹¹ These procedures are increasingly common as the baby-boom generation moves through its sixties and seventies, and for many patients they represent a permanent exit from glasses-wearing.

Still, glasses remain the default correction method for the vast majority of Americans, partly because they are the cheapest option, partly because they require no surgery or daily maintenance, and partly because many people who are fine candidates for alternatives simply prefer the familiarity and safety of frames on their face.

The Economics of Corrective Lenses

Vision correction is a multi-billion-dollar annual expenditure. An analysis of national data from 1999 to 2002 estimated that the direct cost of correcting distance vision impairment in the United States was at least $3.8 billion per year, with $780 million of that going toward people over age 65.¹² Those figures predate two decades of price increases, rising myopia rates, and an aging population, so current costs are almost certainly higher.

The retail eyewear market has shifted in recent years. Online glasses retailers have driven down frame and lens prices for people who already have a prescription, but the exam itself remains a gatekeeper, and exam costs vary widely depending on insurance status and geography. For people without vision insurance, an eye exam and a pair of single-vision glasses can easily cost $200 to $400 out of pocket, a meaningful expense for a household near the poverty line. Progressive lenses, which most people over 45 need, cost more. The cycle repeats every one to two years as prescriptions change.

This financial pressure helps explain why affordability gaps in glasses ownership track so closely with income and insurance status. The product is relatively simple technology, but the system of exams, prescriptions, and retail markup keeps it out of reach for a segment of the population that demonstrably needs it.

Blue-Light Glasses and Nonprescription Eyewear

A growing share of Americans now wear glasses that have nothing to do with refractive error. Blue-light filtering lenses, marketed as reducing eye strain from computer screens, have become popular among office workers and students. Whether they actually work is debated. A small pilot study among radiology residents found that blue-light filtering lenses reduced the severity of most measured computer vision syndrome symptoms compared to sham lenses, though the study was too small to draw firm conclusions.¹³ Larger and more rigorous trials have been less enthusiastic, and major ophthalmology organizations have stopped short of recommending blue-light glasses for the general population.

Nonprescription reading glasses, the kind you grab off a drugstore rack, are another huge category. They work well for simple presbyopia and cost a fraction of custom lenses. For many Americans over 45, these are their first and sometimes only pair of glasses. They do not appear in most clinical surveys of “glasses wearers” because they are purchased without a prescription or eye exam, which means the true rate of glasses use in the United States is probably somewhat higher than survey data suggest.

Fashion eyewear with no corrective function at all has also become a notable cultural trend. Glasses have shifted from a medical necessity that many people felt self-conscious about to a deliberate style choice, and some people wear frames with plain lenses purely for aesthetics. This complicates the simple question of what percent of Americans “wear glasses” because the answer depends on whether you mean corrective lenses, any lenses marketed for eye comfort, or anything with frames on a face.

Age and the Inevitability of Presbyopia

If you do not wear glasses now, you almost certainly will eventually. Presbyopia, the gradual stiffening of the lens inside the eye that makes close-up focus difficult, is essentially universal. It typically becomes noticeable in your early to mid-forties and progresses through your fifties. No amount of screen avoidance, eye exercises, or carrot consumption prevents it. By 65, nearly everyone who does not have another form of correction (such as an intraocular lens from cataract surgery) needs reading glasses at minimum.

This biological reality means that the percentage of Americans wearing glasses rises sharply with each decade of life. Surveys of adults consistently show that glasses-wearing rates among people over 65 far exceed those of younger groups. When presbyopia is layered on top of pre-existing myopia, the result is often progressive or bifocal lenses, which correct both distance and near vision but are more expensive and take some adjustment to use comfortably.

Presbyopia also reshapes the market for LASIK. People who had successful laser surgery in their thirties to eliminate nearsightedness often find themselves reaching for reading glasses by their late forties anyway. Some opt for a strategy called monovision, where one eye is corrected for distance and the other for near, but this involves trade-offs in depth perception and is not for everyone. The point is that very few people escape some form of glasses use across an entire lifetime.

Myopia Severity Matters Too

Not all nearsightedness is the same, and the rise in myopia prevalence has been accompanied by a rise in high myopia, the more severe form. National data showed that the prevalence of myopia worse than about -8 diopters increased eightfold between the 1970s and the early 2000s, from roughly 0.2% to 1.6%.¹ High myopia is not just a matter of thicker lenses. It carries meaningfully higher risk of retinal detachment, glaucoma, and macular degeneration later in life, conditions that glasses cannot fix.

This is why eye-care professionals are increasingly focused on myopia control in children rather than simply prescribing stronger glasses every year. Strategies like atropine eye drops, specialized contact lenses, and encouraging outdoor time aim to slow the elongation of the eyeball during growth. The goal is not just to reduce how many kids need glasses but to keep their prescriptions from reaching the range where serious complications become likely decades later. Whether these interventions will bend the long-term curve remains an open question, but the urgency is real given where the prevalence numbers have been heading.
