I wanted to start with a flashy topic to get attention. As some of you remember me writing, I have had PWM sensitivity for 30 years and sensitivity to modern (since about 8 years) laptops and computer displays, even if they don't have PWM.
About a year ago, my eyes started getting blooshot and very irritated with every display I was using at the time, without any changes to software or hardware. Even my Motorola G100 phone which I was using sometimes many hours a day to browse twitter, started suddenly cause significant eye strain. All the TV's also the same.
I started blocking my right eye with a tape to the eyeglass and continued it until about a month ago. I tried several times during last summer and fall, if I could tolerate without the tape, to no avail. I watched TV in the evenin always with a tape in my glass.
Sometime in the fall I noticed that my Lenovo x280 is the only device I could use without the tape. So I worked 10h a day with that computer without any symptoms. Teams video did cause eye strain, tough.
Late last year I got norma progressive eyeglasses and started using them all the time, but did not see any improvement.
About a month ago, I started noticing that I can use my phone without the tape without any, or at least any significant eye strain. Now I sometimes browse social media for hours in the evening, without any eye strain on that same Motorola G100.
I also watch TV without the tape, but sometimes feel that if I have used the phone a lot and I have a normal 10h workday, TV does seem to cause some strain, but I'm able to tolerate it and I don't have those very irritated eyes next morning.
So, at least for now, I seem to be recovered to almost the same status as I was a year ago, so that only the modern laptops and screens and PWM (oled also) do cause eye strain, but some screens without PWM do not.
The only thing that I can think of that could affect this, are the eyeglasses, that I wear all the time now. Previously I was not needing them, but now of course everything is that much sharper that I prefer to use them, but I could still do without.
Could it be that the glassess actually have made some change in the way my eyes work, or maybe they relax my eyes somewhat, so that I can tolerate screens better, as my eyes do not need to try to focus all the time.
I had tried reading glasses prior to this and was always using long range glasses to watch TV previously, so there was no big change in that aspect.
Anyway, I don't think it is due to the glasses, I think that somehow any strabismus or BVD just improved on it's own suddenly.
