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.
