I bought an IPhone 11 pro a week ago to replace 6s+. I read about the PWM here so I was concerned if my eyes would be sensitive to the new screen. The first two days I didn’t use the new phone too much then since day 3 I started having this tension headache and slight dizziness that’s just not going away. I tried all the setup suggestions on Internet and even bought a pair of computer glasses, I’m feeling slightly better but the headache is not gone 100%. I just switched back to my old 6s plus and if the headache goes away in a day or two, I will return the 11pro next week. Now I’m torn if I should give 11 a try or just keep my 6s plus for another year..
