Fact-checked via 4-step process— how we build this report

01Primary Source Collection

Data aggregated from peer-reviewed journals, government agencies, and professional bodies with disclosed methodology and sample sizes.

02Editorial Curation

Human editors review all data points, excluding sources lacking proper methodology, sample size disclosures, or older than 10 years without replication.

03AI-Powered Verification

Each statistic independently verified via reproduction analysis, cross-referencing against independent databases, and synthetic population simulation.

04Human Cross-Check

Final human editorial review of all AI-verified statistics. Statistics failing independent corroboration are excluded regardless of how widely cited they are.

Statistics that fail independent corroboration are excluded.

In 2025, there are 43 million people worldwide living with blindness, a number that stays stubbornly high despite decades of vision research and screening. What makes the figures harder to ignore is how uneven the burden is across regions and causes, with some conditions preventable but still widespread. The statistics below break that contrast down by eye condition and demographic, so you can see exactly what is driving the totals and what might change them.

Prevalence Interpretation
