Although 3D TV is relatively new and still is being tested for health risks, manufacturers like Samsung have already posted warnings that the technology could cause seizures. Researchers at the University of Munich and University of Salzberg may have shed some light on the situation, as they have conducted what appears to be the first reported study about the potential effects of 3D TV on epilepsy patients. They exposed a small group of more than 100 children to two different stimuli: 20 minutes of light stimulation and 15 minutes of 3D TV viewing, comparing the difference in EEG response.
Although one seizure actually occurred while a patient was watching 3D, the researchers still concluded that 3D TV viewing "did not increase epileptic activity on EEG" or cause seizures in children with a risk of epilepsy or known epilepsy; and that it's also unlikely to lead to seizures in people with undiagnosed epilepsy. With such a small sample size and short period of 3D TV viewing, more studies are needed before we can safely conclude that 3D TV doesn't cause seizures. At least researchers did find that subjects experienced at least some of the commonly heard negative side effects of 3D TV: 20 percent reported nausea, headache, and dizziness.
