Strobes can really mess you up. That's why the lights on Police cars strobe. A few years ago the was an animated movie that included a character with flashing eyes. The frequency of the strobe effect caused nausea and vomiting in viewers .
That was a Pokemon cartoon that aired in Tokyo in 1997. Supposedly kids up to a certain age are more susceptible to photosensitive seizures. That incident sent more than 700 kids to the hospital.
Now for the tinfoil hat...
You all have seen or heard of people recounting their abducted by space aliens stories. They even made a movie about such an incident and called it " Fire in the Sky" :

One company makes a flashlight called the puke light:

That science fiction has been turned into fact. Somebody got a patent on it according to this link:

Inside this area they had erected a black tent. I went inside the tent and got to experience the strobe feature of their then new Blackhawk Gladius flashlight. After a few seconds, I got dizzy. The demo person then went on to say that the strobe also allowed you to close on people. About 3 seconds later I felt his index finger pressing against my temple. I didn't even see him
Move from about 3 to 4 feet away. That part was kinda spooky.
