This is very interesting. I concur with Jen’s assessment in that thread. I would add that I’ve noticed certain frequencies and modulations seem to affect different things: the eyes vs. brain. As it relates to the eyes I’d imagine color and luminosity to be a big one, then you have a crossover between the eye muscles and nervous system, and of course the brain itself which seems to be where the most severe symptoms are triggered.
My guess is that it’s also a matter of overload through increased stimulation. There are too many things going on at once on modern screens and I think as a result they are more likely to surpass someone’s tolerance.
