Why Investing in Eye Health is One of the Smartest Decisions We Can Make

Over the years, through Orbis and our partners, I’ve seen first‑hand what happens when people gain access to something as simple—and as transformative—as good vision. I’ve also seen the cost of inaction: children struggling in school and suffering poor mental health because they can’t see the blackboard, adults forced out of work years too early, families pushed deeper into poverty, road users threatened by unsafe traffic, and communities bearing avoidable social and economic loss.

That experience is what brought me, along with my colleagues, to contribute to the Vision Atlas Global Investment Case. The Atlas brings together the best available global data on vision loss—its scale, its consequences, and, critically, the opportunities we are currently missing.

The conclusion is a simple one. Investing in eye health is one of the most effective, scalable, and human‑centered development tools available today.

More than a billion people worldwide are living with vision loss that could be prevented or treated with existing, low‑cost interventions. This is not because we lack solutions. In many cases, it is because eye health has been treated as a specialist concern rather than as a foundation for education, economic participation, equity, mental wellbeing, and safe communities.

Speaking simply, governments, industry, those with the power of the purse, have under-invested chronically in eye health, simply because they have underestimated its impact on human life. Glaucoma and cataract may not kill as cancer and measles do, but this new evidence shows that spending to improve vision is a bargain, and is as life transforming as any investment in all of medicine.

At its core, it means scaling solutions that are simple, proven and affordable. The Vision Atlas highlights a small number of “accelerator” interventions—things like early detection through community screenings, access to glasses, improved cataract surgery, increased capacity, additional resources for eye teams, and integrating eye care into national health programs. These are not experimental interventions: they are already proven to work.

The global investment case modeled through the Vision Atlas shows that spending some US$7 billion between 2026 and 2030 in low‑ and middle‑income countries will deliver nearly $200 billion in economic benefits. In global health terms, that is a remarkably modest sum — and an extraordinary 28:1 return on investment.

In the Vision Atlas, we framed impacts around five interconnected areas—what we call the five Es: Education, Economics, Equity, Emotional health, and Environmental health. Seen together, they tell a powerful story. Below, is a breakdown of each area.
 

Education: Seeing clearly is fundamental to learning

One of the most consistent findings in vision research is also one of the most intuitive: children learn better when they can see.

Randomized trials in China and elsewhere, many led by Orbis, have shown that providing glasses to children with refractive error leads to significant improvements in academic performance—with effects larger than those associated with family income or parental education. In fact, among school‑based health interventions, vision correction stands out as the most effective proven way to improve learning outcomes.

What matters almost as much as the impact is the how. When glasses are delivered directly through schools, as in Orbis’s REACH India initiative, uptake increases dramatically. Barriers fall away; children wear their glasses; teachers see the difference; learning improves; brighter futures are unlocked.

If we are serious about achieving quality education for all as called for in SDG #4, then eye health cannot remain a peripheral issue.

Economics: Eye health is a livelihood accelerator

For years, global health has struggled to demonstrate direct economic returns on investment as a poverty alleviation strategy in service of SDG #1. Vision care is an exception.

Multiple randomized controlled trials across different countries show that correcting vision enhances productivity and increases income, by 20-30%, in fields from agriculture to handicrafts to manufacturing. Cataract surgery, one of the most common and cost‑effective surgical procedures in the world, can increase personal income by over 50%. 

Orbis research is at the centre of this important evidence.

These are not abstract gains. They translate into food on the table, school fees paid, reduced dependency, and dignity restored. They also accrue at scale: when millions of working‑age adults can see clearly, productivity is increased and national economies benefit.

In an era where development funding is under pressure and value for money matters more than ever, eye health consistently delivers returns exceed most flagship health and development interventions. As noted above, every $1 invested in eye health is now shown to yield $28 in economic gains, largely driven by impacts in the workplace. This represents one of the greatest bargains in healthcare.

Equity: Vision care reduces inequality where it matters most

Vision loss does not affect all people equally. It is concentrated among the poorest communities, older adults, women, and those living in low‑ and middle‑income countries. The injustice is stark. The people least able to absorb the consequences of vision loss are the most likely to experience it.

The good news is that many eye health interventions are uniquely well-suited to closing these gaps. They are low‑cost, highly scalable, and increasingly deliverable through community‑based and primary‑care models. Older workers and women often experience the largest productivity gains when their vision is corrected—precisely because they bear the greatest untreated burdens.

Examples of Orbis’s scalable models include women‑led green vision centers, which bring affordable, high‑quality, and environmentally sustainable eye care closer to women in rural communities, while providing them with leadership and livelihood opportunities. Alongside this, Orbis’s school eye screening programs identify and treat vision problems early, greatly enhancing access for girls, who are less likely to visit traditional healthcare facilities. The enhanced opportunities for women and girls delivered by eye care propel progress towards gender equality, as envisioned in SDG #5.

In parallel, Orbis advances equity‑based eye care through technology and leadership opportunities. Cybersight helps women overcome barriers to training, providing free and flexible webinars, remote mentorships, and consultations. Women Leaders in Eye Health complements this by building women’s skills, confidence, and influence across the eye health workforce, ensuring that leadership and decision‑making reflect the communities most affected by vision loss.

Emotional Health: Improved vision leads to better mental wellbeing

We increasingly recognize that we are in the midst of a mental health crisis today. What is less widely appreciated is the role vision plays in emotional wellbeing, particularly for children.

Orbis-led systematic reviews show that children with vision impairment experience significantly higher levels of anxiety and depression than their peers. Vision loss can lead to social isolation, loss of confidence, and reduced participation—outcomes that shape a child’s entire life course. 

The Orbis SWISH study in China is just now completing collection of data designed to demonstrate that delivery of a simple pair of glasses in schools can reduce these avoidable mental health burdens.

Among older adults, emerging research suggests that vision correction may even help to slow cognitive decline and prevent dementia. While this work is ongoing, it points to an exciting and largely unexplored frontier in healthy aging.

Eye health, in other words, is not just about seeing better. It is about living better, in service of SDG #3 and its drive to deliver universal good health and well-being.
 

Environmental health and safety: Vision saves lives

Vision is also fundamental to safe environments—on roads and in workplaces, delivering the sustainable communities envisioned in SDG #11.

Road traffic accidents are the leading cause of death globally between the ages of five and 29 years, an extremely vulnerable and consequential group, representing the future of any society. Fully 90% of this burden falls on road users in low‑ and middle‑income countries. 

Orbis's systematic review, concentrating for the first time on drivers in LMICs, provides the best available evidence on how vision care can reduce this burden: the risk of crashes is nearly 50% higher in those with vision impairment.

Using these data, the Vision Atlas estimates that investing in proven eye‑health interventions could avert 5,847 road traffic deaths and 211,137 road traffic injuries by 2030.

Many eye health interventions rank among the most cost‑effective in all of medicine. Cataract surgery, refractive correction, and childhood vision screening generally outperform interventions targeting far better‑funded conditions

What makes eye health even more compelling is the self‑sustaining potential of these interventions. High willingness to pay for glasses, rapid productivity gains, and relatively simple delivery models mean that investments continue to generate returns long after initial funding.

The Vision Atlas Global Investment Case brings this evidence together to guide smart financial decision-making by governments, donors, multilaterals, and other investors seeking the greatest impact for their money.

At Orbis, we already have the tools. We already know what works. Together with our partners, we’ve been delivering the best vision care to those in the greatest need for over 40 years. What has been missing is greater investment, and the recognition that eye health is an essential part of smart and impactful healthcare planning.

If we are serious about delivering on the promise of the SDGs for robust and inclusive economic growth, effective and accessible schools, universal health and mental well-being, safer roads and sustainable communities, then investing in eye health right now is truly a bargain we cannot afford to miss.
