When you support a Prevent Blindness Texas event, join our Circle of Caring, or volunteer with PBT you are supporting the work we do which benefits the community by providing critical eye health information and by working with our partners to provide a continuum of quality vision care to medically under-served Texans. Your support is crucial to providing the vision services Texans need. Thank you for your consideration to become involved in the PBT mission to prevent blindness and preserve sight.
