Our Mission The mission of Prevent Blindness Texas is to prevent blindness and preserve sight. Who We Are Established in 1956 and incorporated in 1965, Prevent Blindness Texas is the state's leading voluntary eye health and safety organization dedicated to preventing blindness and preserving sight. As such, we focus on improving the state's vision and eye health by enhancing community capacity through our core competencies of early detection, patient support, systems enhancement, public policy, public awareness and health education. Half of all blindness can be prevented, yet this can only occur through these essential interventions. Focused on providing a continuum of vision care, Prevent Blindness Texas touches the lives of thousands of Texans through our sight-saving programs and services through our network of volunteers and offices located in Dallas, Houston, and San Antonio. Prevent Blindness Texas is a 501(c)(3) tax-exempt charitable organization existing under the laws of the State of Texas.
