The Value of Vision: The case for investing in 
eye health

The solutions to sight loss already exist—simple, proven, and affordable. By scaling these accelerators in low- and middle-income countries, we can boost not just eye health, but overall health, learning, employment, and productivity—and achieve one of the best returns in global health.

Increased employment

Individuals with MSVI or blindness are approximately 30%[1] less likely to secure employment compared to those with unimpaired vision. Sight loss limits individuals’ ability to access and retain employment and contributes to substantial society-wide economic productivity losses.  
 
However, evidence indicates that investment in straightforward eye health interventions can swiftly and sustainably reverse these effects. Our analysis suggests that, following the recommended investments, approximately 2.1 million more people could gain employment, resulting in $37 billion additional income over the period of 2026-2030, increasing from $1.1 billion in 2026 to $15 billion by 2030. 

No data available

Enhanced occupational productivity

Individuals working with uncorrected vision impairment experience reduced productivity compared to their colleagues with good vision. This is caused by barriers to performing visual tasks and reduced access to information, as well as physical discomfort, isolation, and mental health challenges that further impact effectiveness. 

Evidence across diverse contexts shows that correcting near vision impairment can significantly boost productivity or income – by anywhere from 6% up to 67%,[2][3][4][5][6][7] often with nearly immediate effects.  

Adopting a conservative estimate of 10%, we expect this intervention to generate income gains totaling $115 billion during 2026-2030, starting from $7.5 billion in 2026 to $43 billion by 2030. 

No data available

Reduced caregiving burden

Caregivers of individuals with vision impairment face substantial demands that affect both their productivity and quality of life. Many of these caregivers – the majority of whom are women – would otherwise be active in the workforce. However, balancing caregiving duties with employment can lead to reduced working hours, unexpected absences, or even withdrawal from the workforce. 

By restoring vision, this burden can be eased by freeing caregiver time for employment and other productive activities. Employing conservative impact assumptions, we estimate that improved vision could unlock a total of $20 billion additional productivity, starting from $726 million in 2026 to $7.7 billion by 2030.

Improved learning for children

Caregivers of individuals with vision impairment face substantial demands that affect both their productivity and quality of life. Many of these caregivers – the majority of whom are women – would otherwise be active in the workforce. However, balancing caregiving duties with employment can lead to reduced working hours, unexpected absences, or even withdrawal from the workforce. 

By restoring vision, this burden can be eased by freeing caregiver time for employment and other productive activities. Employing conservative impact assumptions, we estimate that improved vision could unlock a total of $20 billion additional productivity, starting from $726 million in 2026 to $7.7 billion by 2030. 

No data available

Fewer road crashes

When people can’t see, they can’t drive safely. That’s why in most countries, good vision is necessary to receive a driver’s license. But in LMICs, driving license systems are often poorly enforced or widely informal. 

Poor vision increases the risk of road traffic accidents by nearly 50%.[8] Traffic-related mortality is the leading cause of death among individuals aged 5–29[9] in LMICs with profound consequences for individuals and their families. 

Our analysis suggests vision correction could reduce this burden saving an extra 5,847 lives and preventing more than 211,000 traffic injuries over 2026-2030. 

No data available

Improved mental health

Sight loss is closely linked to mental health. There is consistent evidence that losing sight or living with eye disease significantly increases the risk of depression. Approximately 25%[10] of individuals with vision impairment experience depression or depressive symptoms, and similarly caregivers can also be affected by depression. 

Evidence consistently shows that restoring vision significantly improves an individual’s mental health. About one in five of these cases associated with vision impairment can be alleviated through vision correction. By 2030, we estimate the avoidance of 1.7 million cases of depression.  

No data available

Increased longevity

Vision impairment not only affects the eye, but exacerbates health, longevity and quality of life challenges as people age. 

Vision impairment is also associated with a heightened risk of mortality, particularly among older adults. The risk is nearly doubled [11] in individuals with MSVI, and is compounded by comorbidities, cognitive decline and an increased risk of falls and injuries. 

Focusing on the 65–75 age group, our analysis indicates that improved visual health could prevent approximately 12,300 deaths and yield nearly 80,000 additional years of life within the next five years.

Accelerators in eye care needed

This investment case outlines a clear path to reduce the significant but addressable burden of visual impairment. It recommends six practical accelerator interventions – two for all settings and four tailored to middle-income countries. These are designed for rapid impact within one to three years at low cost, while also strengthening the eye health workforce and building sustainable systems for the long term.

Early detection through screenings in the community

Large numbers of people, especially in rural and vulnerable communities, never enter the eyecare pathway simply because nobody checks their vision. Vision and eye screening is a simple, low-cost process that can be carried out effectively by community members with minimal training and equipment.  

Mirroring successful programs around the world, our investment scenario envisages a large expansion of screening capacity to rapidly reach underserved populations. Moreover, scale-up of screening will expand the pipeline of eyecare consumers, improving overall financial sustainability of the eyecare system.

$1.07 billion
Give out reading glasses on the spot

Presbyopia is the single largest cause of uncorrected vision loss, yet it is among the easiest and cheapest conditions to treat. Ready-made near-vision glasses, which can cost less than $3 per pair, can be fitted on the spot by trained community screeners. Our investment case mirrors successful programs globally and recommends enabling existing community workers to screen and dispense ready-made near vision spectacles. 

To realize its full impact, specific legislation will be required in some countries to authorise non-clinical personnel to provide this service.

$345 million
Increase workforce capacity for eye exams and dispensing glasses

As screening volumes increase, it will reveal more individuals who require refraction, and examination for possible cataract. Current shortages in eye care professionals should be addressed immediately to meet this growing demand. We recommend a multi-faceted strategy: 

  • Rapid mid-level personnel training & deployment – Train mid-level eye care professionals such as vision technicians in ~12 months to provide quality refraction services and eye health exams at community level at a substantially lower cost;  
  • Mobile eye exams – Redeploy and incentivize mobile screenings and services to include the provision of on-the-spot refraction exams and glasses dispensing, to increase ease of access, efficiency and uptake;  
  • Tele-refraction – Deploy tele-refraction, serviced by remote optometrists, to extend clinical reach and boost patient volumes;  
  • Increase training of optometrists – Begin immediate additional optometrist training so qualified professionals enter the workforce in 3-5 years for more complex care.

$2.24 billion
Boost surgical productivity and teams

Surgeons are one of the scarcest and most valuable cadres in eye care. The productivity of the existing surgeons can be significantly enhanced through more streamlined workflows. Evidence from successful programs show a 40-50% increase [12] in surgical productivity through interventions such as task-shifting of suitable functions to allied health personnel, optimizing surgical workflows to promote specialization, and ensuring optimal level of equipment and consumables. 

Training enough allied health workers will be essential to support these changes. Additionally, we need to begin training more surgeons and ophthalmologists today to meet growing demand for eye surgeries in the medium and long term.  

Total five-year investment needed for this accelerator
$3.07 billion
Remove barriers to access

Even when eye care services are available, many people do not access them due to barriers such as cost, distance, and stigma. Evidence shows that uptake of eye care increases when cataract surgery and glasses are provided free or at subsidized rates. Bringing services closer via community screening, community-based cataract surgery, subsidized transport, delivery of glasses and tele-health also improves access. Barriers such as fear or stigma should be addressed through health promotion and in some contexts through tailored counselling.  

Hence, our investment case envisages the effectiveness of financial and transport support alongside culturally appropriate counselling to expand access to eye care.

Make cataract surgery even better

Cataract surgery is generally safe and effective, but a certain number of patients do not achieve clear vision after surgery. In many cases, this is due to residual refractive error, which can be easily addressed with a pair of glasses after surgery. This is a low-cost and achievable approach to ensuring cataract surgery leads to improved visual outcomes. 

More broadly, visual outcomes after surgery can be improved through strategies implemented across the full-cycle of surgery including better training and pre-operative biometry. Our investment case projects the potential impact of these strategies in improving surgical quality and visual outcomes.
