Sorry to hear that it’s giving you some trouble. I actually had a very similar experience - the first few days were virtually symptom-free, then I started getting headaches. It culminated in me feeling extremely nauseous, and that’s when I decided to give up on it.

That's very interesting - your experience seems to mirror mine. I've been feeling nauseous since yesterday and woke up today with the familiar brain fog, low mood and nausea that I remember from my MacBook days. Using the phone seems to exacerbate symptoms quickly now, which is very disappointing after such a strong start.

Suffice to say, it's going back to the store - I'm not going back to this feeling again for anything.

What is your usable phone @bkdo? My iPhone 8 is usable in 20 minute bursts throughout the day, but not for gaming or anything. I'd really like a camera upgrade more than anything.

Also curious to see if anyone is finding positive moves with new Apple hardware. I guess my next test will be of the new mini-LED screen tech in MacBooks next year.

      I feel really negative about the future of Apple hardware. M1 Macbook has the most intense multilayered dithering patterns I have ever seen (as visualized through an e-ink displayed). Apple is going for the most eye-popping and dazzling display possible. They do not care about anything else. Hyperbolic? Maybe, but I really feel this way.

      Many of us thought that the graphics driver rewrite for the M1 chip would bring benefits. Instead it makes things worse and the majority of us cannot use this device at all (I realize some can). MacOS Monterey is reported to bring no benefits.

      There is a massive thread of MacRumors about Apple's PWM-infested mobile devices which has been going on for years. Not even MacRumors will acknowledge it. Very sad.

          I’ve been using the iPhone 8 + since 2017. It’s not perfect eye strain wise, but the symptoms are minimal. Unfortunately, after updating to 14.8, I started getting the usual eye strain and headaches that I get on other Apple devices (XR, 11, iPad Pro, etc). Have you tried any of the newer LCD apple products? From my experience, it seems like the two cutoff points have been the A12 chip and then iOS 14.8.

          I feel the exact same way, their displays/software have only gotten worse in terms of eye strain. I’m hoping that whatever graphics tricks (dithering, etc) they’re utilizing will eventually become unnecessary due to better screens at cheaper prices. Though that’s probably a long shot.

              Interesting find! I would love to find a way to quantify the temporal dithering used on displays. Is there a way? A test? A device?

                Thanks for sharing this! I had a theory that these newer Apple LCD devices had some sort of flicker, I could just never find out exactly what it was.

                  Is it possible to take a video of this and potentially send it to Apple? Or even just upload it here?

                  If there is a test for it, and we can point and say this is the problem.

                      mike In 2-3 weeks i will get my iPhone 13 Pro, can’t wait.

                      Any luck with the iPhone 13 Pro and your patching?

                          Got it last week. But are waiting for a Zagg Glass XTR screen protector before I start using it, that will arrive in a couple of days.

                          I will keep you posted.

                            Interesting.. notebookcheck says the 13 mini is 510.2 Hz pwm, while the pro is half that which is the # we are all used to seeing. Might be better for folks here to consider the non-pro version instead, if they have their hearts set on Apple.

                              I wish the color profile could be changed or weakened since the dithering over time is my nemesis. Never the less, that’s good to know.

                                Now I have used my iPhone 13 Pro for two days.

                                First I looked with both eyes, I could feel a little tension so I looked at the screen with one eye for half an hour. After that I look with both eyes without getting tension headache. I have done this procedure with 7-8 new screens. That’s what I need to do, thanks to all training. Yesterday I got 8+ hours of screen time, I can feel that in my eyes, but it’s not that bad. It’s to early to say, but I guess it’s like my iPhone 11 Pro for the eyes.

                                  Just a note. I’ve been fine with my XS for years (only if I have reduce white point on 95%) and reduce motion, otherwise it’s unusable. I updated to iOS 15.01 the other other day and it became unusable with severe nausea. I looked through all settings and trialed various filters etc. nothing worked. Then I tried ‘differentiate without colour’. It does something I can’t put my eye on, but changes the colour profile v subtly and since then it’s usable again. If I uncheck it I get the nausea. May be worth people trying….

                                    Out of curiosity, what iOS version were you on before you updated to 15.01? I noticed a change in eye strain when I updated from 14.6 to 14.8, so it seems something definitely changed at least around then.

                                    That's interesting that "Differentiate without Color" seems to help you. From my understanding, that setting is for color-blind people, I'm curious if does change something that may help our symptoms. I'll try it and see if there are any positive changes.

                                        bkdo I don’t know what I was on before and it wasn’t through iTunes so I can’t find out.

                                        Yes do keep me updated if you find anything.

                                          Hi folks,

                                          I just wanted to update with an iPhone 13 success story! As I detailed above, I purchased an iPhone 13 Pro and initially thought it was great. I used it continuously for a few days, and suddenly I had the same old spiralling migraines and nausea. Left eye pain, neck pain and all the trimmings. This got returned.

                                          A couple of months later, and I decided to pick up an iPhone 13 (not Pro). This time:

                                          • I immediately put this matte screen protector on it
                                          • I started very gently - 10 mins at a time for a few days
                                          • I gradually built up my time on the phone over a week

                                          I'm now 10 weeks in with this phone and I'm using it continuously without any issues at all. I can't believe it, I actually have less issues than with my iPhone 8 which I have tried to replace with both the SE and the 13 Pro previously.

                                          As a side note I still can't play games on it - even 15 minutes seems to start giving me issues.

                                          Could the tempered glass matt screen protector be making a difference? Or the lack of Pro Motion maybe - this phone is running at 60hz rather than 120hz? Seems strange, but this is the first OLED product I've ever been able to use.

                                            si_edgey

                                            Congrats on finding something that works, that's great news!

                                            Out of curiosity, have you tried any of the following?

                                            -Using the 13 without the protector to see if the symptoms come back

                                            -Using the screen protector on a different problematic device to see if it prevents symptoms

                                            -Trying different types of games to see if it affects the onset of symptoms (For example, a more graphics intensive game may cause worse symptoms)

                                            -Messing with the brightness levels to see if it affects symptoms

                                            You mentioned that you also tried a 13 Pro a while ago & had symptoms, I'd be curious if you'd now be able to use one if you had this screen protector on as well. The strange thing is that I don't really see anything special about this particular protector (Seems like a standard matte tempered glass protector from what I can see), I'm definitely interested as to what makes this one different.

                                                si_edgey As a side note I still can't play games on it - even 15 minutes seems to start giving me issues.

                                                By games do you mean games with a lot of movement (think Grand Theft Auto, or, racing game)? Or even a crossword puzzle or Scrabble kind of game, would give you symptoms?

                                                I'm fine with the puzzle games but forget about GTA etc.

                                                    This is really good news, let us know more about it. For me I did not have any luck with screen protectors, tried some of them but eye strain was still there. Btw I'm more than happy to try and see if ip 13 works.
