Abstract The Global Burden of Disease study estimates the prevalence of vision loss by WHO severity group, and the distribution of vision loss due to underlying causes such as cataract, glaucoma, and uncorrected refractive error. Data sources include national and local surveys, and scientific literature, with over 500 sources in 113 countries. Cause-specific prevalence estimates were proportionally fit into estimates of total vision loss by severity. Globally, 821.9 million (95% UI=682.2–970.4) people experienced moderate or worse distance vision loss or near vision loss in 2019 (age-standardized prevalence = 0.10, UI=0.08–0.12). Of these, 41.9 million (UI=36.4–46.8) were blin..
