I too have a curved nasal something and I was also told to get a surgery for it. It might be linked with internal skull pressure. I once described my symptoms on another unrelated forum and one guy said he experienced the same when he had covid, linking sinusitis with eye strain.

JonnyT Funny thing - I have no troubles with any other laptop (didn't try oled) but with the m1 macbook. It gives me a headache.
Just a little update. Today I visited a neurologist and she told me that the symptoms that I described in my post are pretty much a muscle spasm due to eye strain. Advised me to see an eye doctor and to take epilepsy test with the smartphone that causes troubles if the eye doctor doesn't find anything.
mike I have for some brief time but with no apparent results. I checked for binocular vision symptoms and I have none of those.
In fact, the most helpful thing for me was using Apple devices under led room lights. They become much more useable than under natural light or in the dark. Perhaps it has something to do with led lighting PWM that makes the phone PWM less apparent.
Thanks for the reply. Yeah, I figured I am not making shit up, so I am planning to see another doctor. At first I thought it was PWM, despite me having a lot of experience with AMOLED. But after completely trouble free experience with S22, which supposedly has terrible PWM, I thought it over and figured that it's just Apple I have issues with. And given that Apple uses Samsung screens it must be something with their software/implementation.

ensete In the past I had no issues with Apple products. Had a 2009 Macbook Pro, several older iPhones and iPads. But the current models that I got give me these unexplainable issues. I don't even know what it is, as PWM is something you can measure and my Samsung phones have it worse. Don't see how a screen protector can change anything but glad it worked for you.

Hello, everyone!
I've never considered myself sensitive to PWM. In fact, I didn't know about it before. I've used Samsung S6, S8, S10+, A52 and now S22. All of them have AMOLED displays. No issues for me after years of usage apart from some slight eyes discomfort when using them in bed at night with no light. But even then I still could easily read from them for hours.
This year I got myself iPhone 13 Pro Max and Macbook Pro 16. iPhone gives me terrible headaches after minutes of use. And after prolonged use I develope pressure in ears and blurry vision that stays with me for days. No eye discomfort though. After 4 days of use I got me ears closed with pressure and headaches started. I dropped the phone but symptoms continued for 3 weeks (strong ear pressure, blurry vision, constant headaches, strange feeling in the forehead, like someone is holding a hand right in front of my face). With Macbook - after several minutes of use all the text gets blurry and I need to concentrate my eyes for text to stay sharp (this is not an issue with iPhone though). Macbook still gives me slight headaches but in much lesser extent. My sister has iPad Pro 12 inch with M1. No headache but my eyes get irritated when watching it.
So, what is it about Apple stuff that makes me feel this way? Supposedly Apple phones use Samsung screens and Samsung has much worse PWM frequences than Apple devices. I hear everyone say how iPhones are much better for your eyes than terrible Samsungs… Macbook's and iPad's PWM frequences are 100 times higher than on my Samsung phones. Yet I have 0 trouble with any Samsung AMOLED screen even at 200hz PWM and Apple screens give me headaches at 14000+hz PWM. Why so?
I got MRI and it showed nothing. My neurologist disregarded my story with a smile and said that it was psychological or it was a result of stress. Should I go to another neurologist or an eye doctor for this? Might this be a result of COVID I had last November?
P.S. interesting thing I observed with my iPhone - using it under room light (led lamps) is much easier than under natural light, no matter how bright it is.
P.P.S. Never had vision problems or PWM issues before, though I work with computers a lot. My vision is perfect.
asus389 In fact I can use both new macbooks and the newest iPad Pro 12.9. The only device that gave me actual headaches was iPhone 13 Pro Max. I am starting to think that perhaps my specific phone is somehow flawed.
Hello, everyone!
I've recently figured out I must be PWM sensitive but I am kinda lost as to the reason behind my sensitivity and would like some advice.
I've had Samsung S10+ for 2 years and it never gave me issues. I get some light pain/discomfort in my eyes if I use the phone in bed at night but I always thought it was cause of tiredness and low ambient light. It never gave me headaches or anything.
Recently I bought iPhone 13 Pro Max and, boy, did I understand I was PWM sensitive in just few days. Just after 2-3 minutes of looking at it during the day I feel like after reading S10+ at low brightness at night for an hour or two. But worst of all - it gives me real strong headaches and pressure in my ears like in an airplane.
But here is the issue - according to reviews and tests S10+ has worse PWM than iPhone 13 Pro Max. I started reading, and apparently S10+ has awful PWM. So, why can I tolerate it but not the iPhone?
To make matters worse - my mother has normal iPhone 13 (not Pro Max) and it also doesn't give me headaches. At least not that fast. And her previous phone S8 also didn't give me any problems. Neither did A52. And all of them supposedly have worse case of PWM.
Is there any explanation for this? Why specifically iPhone 13 Pro Max? Is it really PWM sensitivity or perhaps something else? And my biggest worry - will I have problems with S22 Ultra if I buy it?
I actually had the same thought. I recently bought an iPhone 13 Pro Max and when using it I got headache and pressure in my ears. Then, after 3 days, I started getting headaches and closed ears feeling like on plane every day. I dropped the phone but even 3 weeks after I still have those symptoms, although much weaker.
I figured it can't be just eyes, in facts my eyes feel okay. It must've triggered something in the brain and the brain is now recovering from it. Got an MRI - it's all good. Tried using the iPhone - symptoms return just after several minutes. Funnily, never had anything like that before even though I've been using Samsung S10+ for 2 years and has, supposedly, an awful PWM.
