Severe Eye Strain due to OLED PWM Dimming

Hello , i have been using iphone for 10 years or so and with changes after iphone X which uses OLED , i am really unable to use my iphone due to PWM dimming which causes severe migraine and dizziness for me in 5mins. I have been stuck on iphone 11 due to LCD panels but i am worried whats going to happen in future since LCD is gone now. Can Apple implement DC dimming via software Update? i have tried 14 pro and it had same problems even though flicker has been reduced but doesnt help. I tried every accessibility option like reduce white point , keeping 100% brightness.

  1. I don't believe we're going to get DC dimming for OLED screens as updates.
  2. For those who don't understand what PWM is and how it affects a small groups of people, before asking them to go see an eye doctor, at least read a few articles about how PWM affects their eyes, and in some cases, dizziness and vertigo. Here is a start: https://www.notebookcheck.net/Why-Pulse-Width-Modulation-PWM-is-such-a-headache.270240.0.html
  3. Currently only iPhone SE 3 have LCD screens. The plain iPhone 11 is the last big display iPhone that have LCD and users who are affect by pwm can only use these 2 phones (that is if they can buy an iPhone 11 model). Note that iPhone 11 Pro & Pro Max uses OLED. And any thing from 12 onwards uses OLED.
  4. I am in the same boat as you because I am also affected by the pwm. If apple changes everything to OLED then I just have to say goodbye to iPhone. We are such a small group and I don't think they really care.

We can still use the later iPhones but we need to know what are good lcd screen replacement options because some brands still offer lcd screen replacements for later iPhones. We would just have to pay a bit more to replace the screen when we buy a new iPhone. My question is what brands are the best for iPhone lcd screen replacements for likes of iPhone 12,13,14 etc?

I am a migraine sufferer like 2-3 a year but lately its 2 a week and i suspect my iphone13 pro screen, i have had for 2 years but recently did a update- is there any answers on how to improve this? I lowered white point, have night mode on and also “limit frame rate” in settings, so its stuck at 60 and cant go down to 10 (which apparently makes it worse for us) this is the only thing i can guess thats changed for my triggers - im due for a new phone what type should i get to avoid Oled screen. I thought having a bright screen was a trigger so i always have it so low but seems that could also cause this? Pls help. Its getting ridiculous

I recently purchased the iPhone 13 and was excited to upgrade, but I’ve been experiencing severe eye strain due to its display technology. I’ve tried adjusting settings like white balance, reducing white point, using True Tone, night mode, and even dark mode, but unfortunately, these haven’t alleviated my discomfort.


The Pulse Width Modulation (PWM) used in the iPhone 13 seems to be causing this issue for me, despite my efforts to mitigate it through various display settings. I’m disappointed because I expected a better user experience from Apple’s latest device.


Has anyone else encountered similar issues with the iPhone 13 display? Any advice or solutions would be greatly appreciated.

We're a relatively small group, but I've read 4% or people are sufferers. And I think there are probably more people that are milder sufferers who just have minor eye strain and live with it, without realising it is to do with their phone screen. You wouldn't think it was a big ask for apple to keep just one LCD screened phone in the range. The new SE 4 is going to be oled when it's out. They vaunt oled as being better, but I wonder if it's just a cost saving to have the whole range as oled?

So Apple yet again in 2024 are ignoring eye health with using OLED screens again. Why isnt this subject being addressed by Apple? Do they not care about eye health? Even if someone doesnt feel the effects of PWM eye strain their eye health is degrading because of it. Ive sent several emails to Apple and not once had a reply. Looks like another year with my LED SE
