I am one of those unlucky guys which are sensible to PWM. Last month I returned an XS Max due to eye strain and migraine. Last week i purchased an Apple Watch Series 4 and I am now experiencing the same symptoms. I hoped that without looking at it for more than a few seconds a few times per day i would be fine, but I start to think i should just sell it and avoid oled screens for the foreseeable future. I read of only a couple of persons that actually experienced this, hence why I am posting this here. Does any of you have similar problems? Does it get better?
