I think the dangers of new screens like the Iphone 11 might be severely understated. I was doing some testing and after using an Iphone 6s 4.7" for several hours I can switch my eyes to looking at my PC monitor and pretty much instantly focus on the text and begin reading it (meaning switching your eyes from the phone to PC screen with 0 delay - not standing up to walk over somewhere else).

If I do the same thing with my Iphone 11, all the text on webpages is out of focus like your eyes are in some weird dilation experiment and it takes time before you can even focus to read it normally. Whereas mentioned above, you can kinda switch from 6s to PC monitor seamlessly without any weird delay in being able to focus your eyes properly.

Is this problem specifically due to 8+2bit (or whatever it is) dithering in new panels? I kind of have my doubts since Samsung TN panels with 6+2bit dithering never caused problems for me. If it's due to dithering it would have to be some wildly different dithering method from what's used in TN panels. So the issue is probably something else. Maybe even the specific type of LEDs used in wide gamut panels, or a race to the bottom in Chinese supply chains with just bad LED backlights in general.

I think “dangers of” is a ridiculous statement.
If you’re having trouble switching between using an iPhone 11 and your computer screen, I think your issues are internal.
I switch between IP 14 PM, MBP 16”, iPad Mini 5, IPP 12.9”, and 27” Studio Display all day long without having these problems.
Remember, your eyes are like auto focus, change the viewing distance, the focus has to change. That takes a micro second but it can be noticed.
I can’t believe this thread has been going since 2017 and there are still people complaint.

I'm not young, but I'm not a boomer. In things like video games in the past I typically play at a pretty high level (platinum in League of Legends and higher than that in FPS games). When I've done reflex tests and measured my results against others it was way above average.

The severity of things like PWM affecting people is probably related to biological reaction speed of your eyes. Some people probably see in the equivalent of 1000 FPS while others are pushing 100, and thus have vastly different results. Kind of like how some people claim to not be able to tell the difference in higher than 60hz monitor motion clarity...

I can tell the difference between 144hz and 240hz pretty easily, so there's obviously a lot of human disparity here. Also, never underestimate how many paid shills billion dollar companies will send to crappy internet forums to poison the well about these issues to try and avoid lawsuits. Like the shill posts telling people "just let the glue dry for a few weeks, bro" when people complain about having green-tinted screens (virtually every idevice screen I've seen in the last several years).

No, there is no legit glue drying fix. It's a shill post. What else would you expect from shill-infested, state run media like Reddit and Twitter? In a year or two any forum discussing monitors will probably be entirely composed of chatGPT bots saying "PWM does not exist - nothing to see here."

I came across this interesting post on Reddit (/r/PWM_Sensitive) with further commentrary on LEDStrain.org. OP ordered an after-market LCD (not OLED) screen to put on an iPhone 13, making the device usable for them again!

These "cheap" replacement screens might let us be free of OLED while still using modern phones.

I can't vouch for any particular screen manufacturer, but did anyone give something like this a shot?

Both links are the same?

It's good to read there is an alt version to the OLED panels. Downsides do include: no auto brightness, no waterproof seal, poor colour calibration, phone will overheat. It's a risk.

So it seems almost nobody in here tried 12 pro. And if i remember correctly back then most people were trying 12 pro max, 12 mini and 12 despite 12 pro had the best PWM results….
 
Interested to know if any folks have found the Apple Watch gives them similar eye strain and headache issues as the phones do. Twice this week I played around with a watch in the store for no more than two minutes and I experienced some discomfort .

I'm on a 12 Pro (iOS 16.1.1). The move from iOS15 to 16 gave me some trouble, but that relented after a couple of weeks. It's not totally symptom-free, but I'm not willing to start buying and returning a bunch of other phones. I can usually get away without many/any symptoms on the 12 Pro, unless video is involved. If I watch any video, especially YouTube, I get eye strain, tension headaches, heart palpitations, etc. The same thing happens if I watch anything on AppleTV or HBO using our LG TV Apps or the AppleTV 4K box itself.

Did you try any of the 13s or 14s to compare ?

I have not. Given that I also have issues with a 4K TV, an HP Windows 10 laptop (better with an external 1920 monitor but not great), and a Macbook Air M1, I feel a quest to find a symptom-free device is a waste of time at this point.

I bought a used 6s, 6s plus, and 7 plus (not here yet) to test vs newer devices (already have iphone 11). The 6's are 'okay' to look at, but oddly I feel the Retroid Pocket 3+ (same screen as iphone 6) feels better to focus your eyes on. Only real differences are either Apple software or enormous cellphone EMF (even though I always have airplane mode on).

If anyone wants to try and reduce variables further, you could attempt to wrap your iphone (at least the back where the antennas are) in tinfoil (antennas are located on rear top and bottom edges on phones like iphone 7). If it's not EMF, it's something stupid cellphone companies do like pulsing power on and off real fast to save power similar to PWM but not detected in those tests.

I have a 60hz Samsung PLS desktop monitor that was always easy to look at and just bought a Samsung A23 5g phone to try that, too. The phone screen is definitely more stressful to look at than the desktop monitor for the eyes and brain (similar or a bit worse than Iphone 11). For the screens that don't have PWM and are still annoying to look at, I can't think of any other culprits besides cellphone EMF, the types of LEDs used in phones, or potentially dirty power/flickering power/pulsing power used to save energy in phones.

Most electronic devices use sizable capacitors which provide power filtering/smoother power by default, so if cell phones are too small or companies are too cheap for quality components and speccing too much ripple compared to desktop ones, this could also be a source of problems.

Here's another interesting phenomenon for gaming handhelds.

- Nintendo 3ds XL's ship with both IPS and TN screens. The ones with TN screens you can look at literally all day with no discomfort, while the IPS version is definitely way worse in being able to concentrate to look at it.

- Nintendo 2ds XL ships only with TN and is equally easy to look at.

- Nintendo DSI XL uses only IPS screens and those are better to look at than the 3ds IPS, but SLIGHTLY more strainful to the eyes than the TN screens in the 3ds.

- Sony Vita 2000 ships with IPS screens and are better to look at than the 3ds IPS, but I'd rate it harder to look at than the 3ds TN panel and DSI XL IPS. It kinda has that nagging feeling of creeping irritation like the Iphone 11 screen where you need to look at the device for an hour or so before you notice anything.

I had almost all Samsung Galaxy S models, with OLED screens. Tormented by severe and unjustified headaches, insomnia, irritability. Then my eyesight began to deteriorate. As a result, I gave up these smartphones and use the Iphone 11 with a screen without PWM. To anyone who has symptoms of sensitivity to OLED screens, I advise you to try to turn on the Motion Reduction function in the iPhone settings and tick the "cross-flow preferences". These two options significantly reduce the strain on our eyes. Also use the dark theme on an ongoing basis. In general, you need to boycott the purchase of such devices and pay attention only to screens with a PWM dimming frequency of at least 1440 HZ (like Huawei Mate 50).

Okay, guys. Forget hearsay or memories from 10 years ago. I've recently purchased 6s, 6s plus, 7 plus, 8 plus, and already own an Iphone 11. Out of all those, the 7 Plus has the lowest eyestrain for me. If you want to continue to own an iphone, that's the one you'll want to try and buy off Ebay or somewhere. If you think that sounds like a dumb idea, I couldn't even find a good screen in newer Android models either like Samsung's A23 5G with PLS screen.

This is literally about the only good option. The ONLY screen I haven't used or purchased which is claimed to have low eyestrain is the Moto G100, but the color calibrations on those aren't too hot and I think they're only like 93% SRGB, too. So a 7 Plus with a good screen is just better...

Changing the battery isn't too hard on the 7s plus, or expensive, and you can always bring it in somewhere to do it. The main problem is finding one on sites with a good OEM screen. If you look on Ebay or somewhere for one, I believe the more popular 3rd party screens used in replacement jobs have a bluer tint to them and also lower contrast ratio/saturation. In pictures a lot of them look like they're pushing 7000-7500 kelvin color temperature, while most of the OEM screens in pictures look 6100-6400ish (the OEM is what you want).

Unless there's some kind of screen lottery on the 8 Plus, that one felt kinda similar to the Iphone 11 to me, so wasn't much of an improvement, while the 7 Plus was better than both. The 6's are okay, but the 7 Plus just comes out ahead IMO.

From all of my time spent here, there seems to have been quite a few who, like myself, have gotten on fine with the 11 and no problems. I am not mistaken am I? And most who haven't made it their daily driver chose so not because of the screen, but because of the form factor?
 
I never tried to do the following. Put any of my iPhones with OLED to a steady 100% brightness and reduce white point at 25% and over. Has anyone tried this and had success ?

Can anyone post the PWM frequencies of 12 pro, 13pro and 14/14 pro/14 pro max ??

I do still kind of want to order a new iPhone since I feel like my quality-of-life is higher as a result, but it’s not practical to have a device that causes headaches/migraines during and after use—especially a device that most people use for half of their day.

Why dont people just change the oled screen to a lcd screen replacement?

-Reduced quality, which may be markedly worse than an Apple LCD
-Added cost
-Drawbacks like no auto-brightness
-Warranty concerns

But really for me it’s because the OLED is one of the draws to upgrading. I would need to see the quality of the LCD to know whether I would be happy with the aftermarket modification.
