Why It Matters
Millions of children can't see clearly, and it's holding them back.
Poor eyesight is one of the most common, and most fixable, reasons children fall behind.
Access
Glasses exist. Access doesn't.
According to the World Health Organization, an estimated 2 out of 3 people in low-income countries who need eyeglasses don't have access to them. Uncorrected refractive error remains a leading cause of vision impairment among children and adults in every country1.
For a child, the barriers add up: no eye screening at school, no nearby eye doctor, and glasses that cost more than a family can spare.
Learning
Children who can't see learn half as much.
A 2024 study by IAPB and the Seva Foundation found that children with uncorrected refractive error learn about half as much as children with good or corrected vision. By grade 6, a child who has never had glasses may be learning at a grade 3 level2.
Worldwide, uncorrected vision costs an estimated 6.3 million years of schooling every year, and 83% of that loss falls on low- and middle-income countries2.
Opportunity
Lost learning becomes lost opportunity.
The same study estimates that each year of uncorrected vision in schoolchildren leads to about $173 billion in lost future earnings worldwide2. Behind that number are children who leave school early, earn less as adults and miss chances that should have been theirs.
The good news is that vision screening and eyeglasses are proven, inexpensive and scalable. WHO counts eyeglasses among the most cost-effective of all health interventions1.
One pair of glasses can change a childhood.
