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).

Incorrect again, the variable refresh rate can and does affect users. They say their iPhone 12 Pro doesn’t bother them yet their 14 pro does. The main difference s the display they are not identical. The 14 Pro has a variable refresh rate, indicating it changes its rate continuously. This can create eye strain.

Exactly my point the iPhone 14 pro has a variable refresh rate meaning just because it’s rated for maximum of 120hrtz it can also go as low as 10 hrtz. Which would explain why people with sensitivity may be affected by the 13 pro and 14 pro models more than a 12 pro. Because the refresh rate can be much lower depending on what they are viewing.

I’m the same as you. I’m having to use an iPhone 11 for its LCD screen since even five minutes with any of their other phones besides the SE gives me insane migraines, particularly if I lower the screen brightness (which I need to do because bright light triggers my migraines as well).


I used to buy a the new iPhone model each year outright, however, once they introduced all the new models with only OLED screens (PWM), I had to stop.


I really, really wish I had the option to upgrade to a better phone but I can’t with their current line-up. I’m thankful Apple still has the SE to choose from but the camera and video features are not as good as what I have on my 11 and I’m a vlogger and rely on my iPhone to take my video and pictures.


Apple, if you’re listening: please, please give us migraine sufferers a higher-end model to choose from consistently each year that has an LCD screen option. I’d be willing to bet there’s a lot more of us out there than you realize, than the sufferers’ themselves even realize. You could market them to migraine sufferers to help reduce migraines and I’d be willing to bet you’d make money off them. I’d buy a new iPhone each year again for sure!


Please don’t forget about us with these types of physical limitations - we’re deep in your ecosystem as well and want to stay with you!


Thank you.

Exactly. Many people just don't know what causes it. For example, they may think that it is simply because their eyes get tired from reading. As it would be from reading a book. But the truth it - they wouldn't get that much severe eye strain or wouldn't get as fast if they used PWM-free screens. More people know about the issue - the faster manufacturers will address it in order to keep the customers.

I have the same issue with the 14 and also the 15 (both returned)

I wonder if it's more that the "wavelength" or "frequency" the 14 and 15 use is different/stronger than the previous models. These are the first ones that communicate with satellites, and let whomever know if you're in an accident. So my question is - is the "wavelength" they're on stronger than the previous models?

I went back to my 13.

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.

I have the exact same problem. Once I upgraded to one of the new iPhones with OLED and had to return it and go back to my 7. I ended up “upgrading” to a xr but it seems I won’t be able to get anything else new since they aren’t releasing anything I can use without feeling nauseous and constant migraines. Really sad because I would love to get a new phone. I hope apple hears our calls for help on this and puts out a newer phone that we can use as PWM sensitive people.
