Hello Everyone, Starting a new thread because we believe this warrants a new poll. Many folks in this thread "https://forums.macrumors.com/threads/eye-strain-while-using-iphone-x.2085427/" are still having Eye Strain issues, even when switching to the iPhone XR. So we are trying to decide what the issue is here. If there are still a substantial amount of eye strain / headache issues on the XR, it is not due to PWM. Perhaps it is due to FaceID or perhaps the lower resolution & reading of text? Please do not vote, unless you have read the forum post above and have eye strain issues. We do not need the 'Tin-Foil' hat comments, as we understand that those of you that do not have the issue, do not believe it is a problem. If you do not have any eye strain with any device and feel like you NEED to vote, I put one called "No, you guys are crazy!", feel free to hit that one. For those that have had the eye strain issues, this poll is for us to try and further understand the root cause.
