Strobes and rapidly flashing images can also cause seziures!!
Because of this you might notice on some video game boxes (inside the manual) there is a seizure warning.
I suffered a seizure two years ago not related to strobes or flashing lights but because of alcohol withdrawl (going sober almost killed me!)
But since that day flashing lights, fast moving images will make me a little light headed and qweezy. And if I'm exposed for a extended period of time a headache will follow.
That is one reason I love flight sim it is mellow on the mind!
But I have played some games that flash so much I have to stop because I just don't feel right. Same for music videos, not that there are any worth watching but my head can't take the constent flashing.
So yes it can lead to headaches, and even worse life threating seziures!!!
And it is sad that what some producer/director/editor thinks looks cool, could kill someone if they don't know better than to look away!
Extreme statement maybe, but the facts or out there, just ask your doctor!
