Prevent Blindness

Founded in 1908, Prevent Blindness is the nation's leading volunteer eye health and safety organization dedicated to fighting blindness and saving sight. Focused on promoting a continuum of vision care, Prevent Blindness America touches the lives of millions of people each year. Every year more than 120 million people read, hear or see our messages about early detection of eye disease and prevention of accidents that can cause permanent loss of sight. We train and certify adult and children's vision screeners and screening instructors through the only national program of its kind, providing 20,000 vision screening personnel with the skills they need to help people in their communities.
