Established in 1915 with Helen Keller as a founding trustee, Helen Keller International (HKI) works to save the sight and lives of the most vulnerable and disadvantaged. Headquartered in New York City, HKI offers programs in 21 countries in Africa and Asia as well as in the United States. The organization combats the causes and consequences of blindness and malnutrition by establishing programs based on evidence and research. Each year, their programs directly benefit millions of people, and children are a primary concern. HKI programs address malnutrition, cataract, trachoma, onchocerciasis, refractive error and diabetic retinopathy. HKI has nearly 700 staff and a worldwide annual budget of over $45 million.
