And what makes you believe that the same sort of issues won't start popping out in regards to our ears?
For instance, I kind of suspect noise-cancelling headphones (bose) give me migraines -- I'm still not totally sure. But if you google it up, you'll see lots of people complaining about nausea when using them. Of course, they're probably only fringe cases, but even so..
Of course, our eyes are different organs than our ears, but I'm pretty sure that a large portion of the problem is in our brain, and that would make it highly likely that both groups (people that feel nausea with bose and people with light sensibility) overlap.
