Researchers from the University of Tennessee Space Institute are developing a device which should make eye exams in children a whole lot simpler. The device is called the Dynamic Ocular Evaluation System (DOES) and it can screen the eyes for abnormalities, while the children watch a cartoon or play a computer game. Here’s how it works:
“DOES is low-cost, high-quality, and operator- and child-friendly. It takes about a minute to train someone to use it. 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. Neither eye dilation nor verbal response is required.
