New Comprehensive Vision Testing Device for Children
Added Sep 6, 2012 | Rate View top rated
Eighty-five percent of children's learning is related to vision. Yet in the U.S., eighty percent of children have never had an eye exam or any vision screening before kindergarten. Ying-Ling Chen, research assistant professor in physics at the University of Tennessee Space Institute in Tullahoma, and her colleagues are working to change that with an invention that makes eye exams inexpensive, comprehensive, and simple to administer. Called the Dynamic Ocular Evaluation System (DOES), the device is low-cost, high-quality, and operator- and child-friendly.The test is done as the child watches a three-minute cartoon or plays a computer game. Infrared light is used to analyze the binocular condition and the assessment is reported on-site within a minute.
