I can speak to that. Outside of the PWM realm- I bought an SE2022 a month ago and it was flawless for my eyes, no issues at all (as would be expected). I stupidly returned it because I wanted to try a 13 Mini.... I quickly regretted that not just because of the OLED screen, but realized I actually like the SE better- so I bought another SE that I've been using for a week. On that phone, it makes my eyes feel dry and irritated, sort of a dry/burning sensation. Not severe, but happens every time I use the phone- and it started the moment I started setting it up out of the box.
Clearly there has to be something different about the display on this one vs. the one I had a few weeks ago, even though they are both the same model.
I am sure there is that sort of difference between two phones of the same model in the OLED universe as well, which makes all of this even more difficult.
My situation is so odd, it's not necessarily PWM-related but is still eye discomfort.
As noted above, I had an SE 2022 for the last couple of weeks, and it always gives me a bit of a dry/mild burning sensation in my eyes when I use it. Nothing bad, and it doesn't give me headaches or anything like that- but it doesn't make sense why it does this on a basic LCD phone with no PWM!
As noted I had an SE about a month ago that I had no trouble with, as I returned it thinking I might like the 13 Mini instead- which I quickly returned.
Well I returned the SE today and bought another SE from my carrier- got a good deal with $150 off in special incentives I had on my account and wasn't even aware of, so it was a great, cheap purchase.
However, disappointingly- I have the exact same sensation when using this one. Not sure why I didn't have any trouble with the first SE I had a month ago, but these last two I did! Same settings on all three, same brightness levels, same IOS version, etc.
The only thing I can think of is that maybe I'm just going through a period with my eyes where they are a bit more sensitive, and it's not really the phone per se that is problematic, maybe it would do this now with ANY phone I used? Hard to say....
I am sitting here typing this on my 27" iMac and have zero issues, so it is so bizarre to then look at the display on my SE and have these symptoms hit almost immediately.
So, now that I bought this from my carrier vs. from Apple, returns are not really an option unless I wanted to jump through a bunch of hoops and pay a restocking fee, so I will use it for a few weeks and see if I adjust as I would certainly think I would to a simple, PWM-free LCD. (I love the phone otherwise and would hope to be able to keep it)
One thing I was thinking of is now that we are in the Apple holiday return period, if I might- after 3 weeks or so once I see if these symptoms go away- is to buy a 13 Mini from Apple (LOVE the small size of the Mini and SE, went with SE this time around to get away from OLED as I suspect I have mild PWM sensitivity or at least some sort of sensitivity to the sharpness/brightness of the OLED panels) and try it out alongside the SE for a month or so and see if I feel it is actually better, or in fact worse for me than the SE. I could return the Mini to Apple at some point before the end of the return period if it is just not working out or I don't like it, or if for some reason it's actually an improvement- keep it and then just sell the SE (since I effectively only paid just over $300 for it after the discounts, I could likely get my money back on it that way)
But, I feel so guilty with all of this returning- my wife jokes that the people at my local Apple store know who I am when I walk in the door now since I've been there 3 times to return phones in the last month.
