AB  - Background Global and regional prevalence estimates for blindness and vision impairment are important for thedevelopment of public health policies. We aimed to provide global estimates, trends, and projections of globalblindness and vision impairment.Methods We did a systematic review and meta-analysis of population-based datasets relevant to global visionimpairment and blindness that were published between 1980 and 2015. We fitted hierarchical models to estimate theprevalence (by age, country, and sex), in 2015, of mild visual impairment (presenting visual acuity worse than 6/12 to6/18 inclusive), moderate to severe visual impairment (presenting visual acuity worse than 6/18 to 3/60 inclusive),blindness (presenting visual acuity worse than 3/60), and functional presbyopia (defined as presenting near visionworse than N6 or N8 at 40 cm when best-corrected distance visual acuity was better than 6/12).Findings Globally, of the 7·33 billion people alive in 2015, an estimated 36·0 million (80% uncertainty interval [UI]12·9–65·4) were blind (crude prevalence 0·48%; 80% UI 0·17–0·87; 56% female), 216·6 million (80% UI98·5–359·1) people had moderate to severe visual impairment (2·95%, 80% UI 1·34–4·89; 55% female), and188·5 million (80% UI 64·5–350·2) had mild visual impairment (2·57%, 80% UI 0·88–4·77; 54% female).Functional presbyopia affected an estimated 1094·7 million (80% UI 581·1–1686·5) people aged 35 years andolder, with 666·7 million (80% UI 364·9–997·6) being aged 50 years or older. The estimated number of blindpeople increased by 17·6%, from 30·6 million (80% UI 9·9–57·3) in 1990 to 36·0 million (80% UI 12·9–65·4)in 2015. This change was attributable to three factors, namely an incre
