Prevent Blindness North Carolina was organized in 1967 as a nonprofit health agency as an independent affiliate of Prevent Blindness America (established in 1908). Kenneth C. Royall, Jr. Children's Vision Screening Improvement Program Funded by the North Carolina Legislature, this program is based on a three-hour curriculum endorsed by members of the Pediatric Vision Screening Task Force and the Children and Youth Section of the Department of Health and Human Services. Workshop participants are trained in the fundamentals of vision screening techniques. Optional testing for color and near vision are also discussed. Participants passing performance criteria and a written test are awarded a certificate which qualifies them to perform vision screening in their representative schools. Through this program, PBNC hopes to ensure that all persons conducting school vision screenings in grades K-6 are doing so in a consistent and uniform manner. Trainings and screenings are available in all 100 North Carolina counties. Preschool Photorefractive Vision Screenings PBNC offers photorefractive vision screenings to preschoolers in many North Carolina counties. Last year, approximately 34,000 preschoolers were screened. Adult Vision Screenings PBNC conducts adult vision screenings at health fairs, senior centers, corporations, malls, and at the State Fair. Approximately 8,000 adults are screened annually.
