Well darn, that seems a pretty good reason to swap a CRT for and OLED, at least on the face of it.
I have no directly relatable experience at retrofitting OLEDs (lol, seems strange, said in this context).
Oh right, I recall that thread now. The usual suspects turned up to roast you, oh dear
I do believe what you were saying/experiencing. Though also admit I that I don't understand what is going on or whether it is EMF sensitivity or whatever. Still seems more likely that it is something like eye strain or some hidden condition like epilepsy. Which is not good. See a doctor.
You mentioned a skin irritation "burning" sensation, something like sunburn. Has this produced any observable symptoms like a rash or blistering? This is physical evidence, show it to a doctor.
Of course, it is theoretically possible that a CRT could be emitting X-rays. That could be an issue if you spend a lot of time working at the back of one??? Seems a unlikely culprit, but you can get a meter to measure that.
Personally, I try to spend no more than 2 hours in front of a screen, any kind of screen, before taking a break. I get tired eyes, headaches, even nausea if I push too long. Extreme light sensitivity. Sometimes stabbing pain and flashes in my peripheral vision if I really push too hard. Similar thing happens from too much closeup electronics work with magnifiers and lights, like building GreenAntz
It gets worse as I get older, and spectacles are not a realistic option. I worry about glaucoma. I consulted with my optometrist about this recently, he did the usual tests and just shrugged like "all is reasonably good, happens to everyone".
So you're OK when playing console games with a CRT+GreenAntz, where you are probably 1-2 meters away from the screen? You still get similar symptoms from watching an OLED over a longer period. This honestly does sound like eyestrain
We mostly tend to get more long-sighted as we age, it gets harder to see things up close.
