New device for eye test
According to latest surveys, nearly 80% of kindergarten students have not had their eyes tested, despite the fact that vision is the most important source of learning in children of that age. Eye tests are only conducted after the child complains of poor vision or constant headaches. The reasons for avoiding tests range from lack of affordability to lack of awareness about the importance of eye tests. In the research carried out in the University of Tennessee, a new method has been innovated that makes the entire procedure easy, simple and affordable. The study has been undertaken by a team of three researchers, led by Ying-Ling Ann Chen, who is a physics researcher. The new procedure of eye testing is easy to administer as well.
Importance of eye testing
According to the lead researcher Ying-Ling Ann Chen, eye testing should not be neglected because the condition of the eye can be an indication of some underlying deeper problems such as dyslexia or autism. Learning disabilities can be easily unearthed by eye testing and the process is now simpler with the new invention. He also said that neglecting eye test can close the window to early detection of problems such as neural disorders.
How does the new test work?
The new invention is called DOES. It stands for Dynamic Ocular Evaluation System. The team of researchers responsible for making this possible, besides Chen, consists of Jim Lewis who is a physics professor emeritus and Lei Shi who is a post doctoral research associate. The new device is meant to be used by pediatricians in order to conduct eye tests easily. DOES has several benefits over the conventional testing devices. It is cheaper, offers accurate performance and offers a very comprehensive eye test. The results of the test can also be used to detect deeper illnesses in children. The test also eliminates the need of providing any kind of verbal response and dilation of the eye.
Conditions that the test can detect
This test can detect some of the most pressing problems in the neural and cerebral system. They are ocular alignment, neural responses, attention deficit hyperactivity disorder, amblyopia, dyslexia, high order aberration, post traumatic stress disorder, autism, to name a few. Further, since the test is very easy to perform and affordable, problems can be detected at an early age in children. Children will not resist to the test because it is simple and does not involve dilation.
