Why is my iPhone 14 Pro causing headache, nausea and eye strain? PWM Complaint...

Hello,


I purchased an iPhone 14 Pro recently. Ever since using it, I have fallen ill with nausea, headaches and eye strain. Even after using for sure durations (5-10 minutes).


Based on my research, this is due to the PWM (Pulse Wave Modulation) flickering which happens in iPhones (and other phones) with AMOLED screens which use PWM to dim the screen.


I currently use an iPhone 11 (standard) - which has an LCD screen with none of these issues.


Is Apple looking into any ways to fix this problem? Or at very least, continue to release phones with LCD screens for those of use with this issue? The only other phone option with LCD and 5G is the iPhone SE 2022...which is a smaller screen phone.


Thank you.

I've had this issue for a while now. (about 5 years now) Took me a while to figure it out, and it's not unique to apple; it's any screen utilizing PWM for brightness control.


As an Apple user, Im sticking with an older MacBook Pro, and for phone, an iPhone 8 (still), and will most likely get an SE by the end of the year.


Most people I know are fine with it. My kids, for example, have no issues. Even friends that wear glasses for reading...not an issue.


For those that do get headaches though, there is one thing we have in common; a lazy eye. I have one eye, not that you can tell by looking at me, that is classified as "lazy". This impacts my depth perception, and typically forces my good eye to do all the work. (the brain is good at adjusting). Seeing those hidden images in a stereogram photo for example? Impossible for me. Anyway, that's what I get for not wearing the eye patch as a kid.


That said, please don't take this as medical advice. It's simply my own personal observation, and experience. All I know is, PWM controlled displays do not play well with my eyes.

Symptoms:


Eye strain/pressure (like I'm staying cross eyed too long)

Nausea/dizzy

Headaches/migraines

blurred vision


Recovery: usually takes a day


Remediation:


I just turn up the brightness. Doesn't work all the time though. iPhone 12 for example, doesn't help, and the symptoms described above tend to come on quickly (few minutes).

Obviously not the right words, BUT tech at Apple Store agreed 14 and 15 do "communicate" or whatever the technical term is, differently, or possibly with more strength, because of the safety features that began with the 14 i.e. if you're lost, out of range, let's say in the mountains, 14 or 15 will find a satellite. If you're in an accident they will notify.

Not PWM because it happens while just holding and not looking at the screen.


Unless you're somewhere with absolutely no cell signal, that type of communication simply does not occur.


I suggest you visit your physician, as RF sensitivity is not a verifiable diagnosis.
