Does flicker trigger epileptic seizures?
Despite the multiple rumors we have heard on this subject, we still have not found any verifiable reports of this occurring. According to the American Epilepsy Foundation, seizures of people suffering from epilepsy and photosensitivity are triggered at frequencies of 5 to 30 Hertz (Hz). Shadow flicker from an large wind turbine, at its highest frequency, is only about 1.25 rotations per second, which is the equivalent of about 1.25 Hz. Therefore, no connection can be made between the two.
