University of Tennessee Researchers Develop Comprehensive, Accessible Vision Testing Device

Eighty-five percent of children’s learning is related to vision. Yet in the United States, eighty percent of children have never had an eye exam or any vision screening before kindergarten, statistics say. When they do, the vision screenings they typically receive can detect only one or two conditions. Ying-Ling Chen, research assistant professor in physics at the University of Tennessee Space Institute in Tullahoma is working to change that with an invention that makes eye exams inexpensive, comprehensive, and simple to administer.
