“What do I do if I have students who can’t see 3D?
While students and parents should obviously listen to their doctors recommendations, the Epilepsy Foundation as well as the American Optometric Association have recently come out with their own 3D findings.
The American Optometric Association for example actually encourages the use of 3D for education, recognizing not only the educational benefits, but the potential health benefits as well. In their study they’ve found that “as many as 1 in 4 US students may be unable to partake in 3D learning activities due to under performance of various aspects of the vision system that have gone undetected and untreated…if an individual experiences any of the 3 D’s of 3D- discomfort, dizziness and lack of depth perception—these signals can serve as an early indicator of some measure of vision impairment. The good news is that, once identified, these conditions generally respond well to treatment.”
Especially in the case of younger students, the American Optometric Association of America actually recommends using 3D in the classroom as a way of better detecting vision problems. Check out eyehealth.org for more info as well as our 3D Resources page for videos.
The Epilepsy Foundation published its findings on Photosensitivity and Seizures, as well as the most comment triggers that cause individual symptoms. Approximately 3 percent of the 3 million Americans with Epilepsy are susceptible to photosensitivity induced seizures. While a combination of factors is what usually help induce a seizure, “the frequency or speed of flashing light that is most likely to cause seizures…are between the frequency of 5 to 30 flashes per second (Hertz)” DLP Link projectors are set at 120Hz for 3D viewing and each “pixel” or lens of the DLP Link glasses are turning on/off at a rate of 60 Hz making it highly unlikely that those suffering from photosensitivity would have problems enjoying their education with 3D technology.
