UT Researcher Develops Comprehensive Vision Testing Device


As the saying goes, eyes are the window to the soul. But to Ying-Ling Chen, Chen: “The eyes are a window to our brain.” That’s because eyes hold clues to fatal optical diseases, neurological, physiological and behavioral disorders and learning disabilities. Unfortunately up to 80 percent of American children have never had their eyes tested when detection and treatment are paramount. Chen: “The parents only bring the children when they are sick and when they sick for doctor they went to the primary care they don’t go to eye doctor.” That’s why the research assistant professor in physics at the University of Tennessee Space Institute in Tullahoma and her colleagues have developed an invention that makes children eye exams comprehensive, easy for easy for health professionals to use and fun for kids. Called the dynamic ocular evaluation system, the test is done as a child watches a short 3D cartoon. Chen: “This is the inferred device that we have. So inferred comes out on the lower pass into this eye goggle. The computer will automatically detect inferred signal and identify it’s the eyes. So it will start it will start to change the image and start to perform the detection of the eye condition.” The current test only tests for one or two conditions. Chen’s invention screens for binocular refractive risk risk, high order apparition, scattering, ocular alignment and significant neural problems it also searches for less significant signs of abnormal ocular alignment. neural responses, amblyopia, and mental statuses that include dyslexia, ADHD, PTSD, and Autism. Chen: “So the eyes will be stimulated and controlled in different angles, different convergence, and illuminated at different intervals of the light source. So the pupil will respond accordingly. And the measurement in inferred without a child’s knowing will automatically measure it in the proper times. So it’s done. And then the computer will produce, will start to analyze the result. Let’s take a look at the results. at the results, what it shows. There are 40 images we took and it’s comparing when the lights illuminate in different locations, the conditions of the eyes to show if it has high order ocular apparition.” The images and results are then digitally recorded so they can be electorally transmitted to specialists for referral if necessary. Chen is currently conducting clinical test at a Wal-mart in Tullahoma. Her vision for her vision screening is to see it improving lives across America. Chen: “”I hope the children come in and where they are waiting, instead of, you know, waiting in the waiting room, those times they can just sit there and watch cartoons and within a few minutes of time their eyes are examined.”
