In my experience, it seems indeed related to some binocular vision dysfunction. Because when I use most of recent screens, it's like it messes with my 3d vision. When I see things after in the real, it looks more 2d like if I was seeing with only one eye.
But the thing is I don't think we suffer from a particular pathology. It's just that those screens would trigger some reaction from our bodies, doesn't mean the problem comes from us. And possibly, everyone would have symptoms, only we pay more attention to them and maybe accept less the discomfort that comes with those recent screens.
If we don't use the screens, we have no problems. I personally had no problem with screens before, it only happened recently and I don't know if the reason is hardware or software or both yet.
The dizziness many people point as symptom would come from one brain hemisphere working less as one eye works less. It would also explain the cognitive issues some have relayed, like impaired memory, feeling sleepy and so on. It messes with the eyes, and then it also messes with the brain and particularly how both hemispheres work.
I don't know if you noticed from recent samsung and philips TVs, but also lgs. If you come close to the screen, the image is very blurry. Like it's obvious something has changed in the technology used the last years. It's very weird, even when the tv is off and you look at yourself in the screen, the image is distorted. Things certainly didn't look as bad before. It impacts tvs, laptop screens, monitors, and even cars dashboards.
