How to minimize Headaches, Migraines & Eye Strains when reading on an iPhone or iPad (Android too)

I recently upgraded from an iPhone 7 to a iPhone 13 mini. The 13 mini is huge upgrade from the 7; battery life, cameras, full screen, phone speed, etc. are wonderful. I had the 13 mini for roughly a week in a half and then bam, I started to notice eye strain. I didn’t get nausea or headaches as some have reported, but just dry eye and noticeable discomfort accompanied by occasional vision blurriness. I was aware of PWM prior to upgrading, but after going to different stores and looking at the phone, it didn’t have an noticeable affect on me at all. Like I previously stated, I didn’t notice the affects until after upgrading and having the phone for roughly a week in a half. Unfortunately, this PWM issue really takes the joy out of using this phone. Even now as I type I can feel the eye discomfort and have to look away periodically and blink rapidly. On a better note, thank you for your video. Using white point, adjusting brightness (to 100%) and using dark mode have helped. I also have significantly reduced my screen time from like 5 hours a day to like a hour and a half a day (if that). I also try to hold my phone at a half arms length distance. In closing, if your looking to upgrade to a phone w/ a OLED screen please be aware of possible eye issues that could occur if you have sensitive eyes like I appear to have. It may be best to go w/ a phone w/ a LCD display like a iPhone 11 or SE 2022; I’ve read these phones have no PWM. Or, if you’re going to stick it out (like I may have to), hopefully Apple releases a software update that helps resolve this PWM issue since it appears to be a software problem. This sucks man lol. I hope this helps. Thanks.

iPhones with OLED screens kill my eyes, give me awful awful headaches and just make me feel very bad. I had two of them before realizing it was the phones causing the issue.

[@sinisterrouge_88]

Thank you SO much! You are very knowledgeable on this topic. I was wondering if you know of any techniques to help when e-readers use PWM on their frontlight (some companies use PWM instead of DC dimming unfortunately). During the day you don't need any light on but I want to be able to use just a tiny bit of brightness at night-time and am wondering if there are any apps or anything that might reduce frontlight flickering?

[@svartling]

They only use PWM when using their super refresh technology. Like onyx Boox. So just use a refresh profile where you don’t use super refresh. I always use HD or HD 256 modes when reading books. Then my onyx Boox or bigme devices don’t use PWM.

[@je36]

I just bought a Kobo e reader but this makes it completely pointless because i personally prefer ibooks for reading! going to get an ipad mini instead, thank you for this! do you still have much use for Kobo e reader with this hack?

[@svartling]

I only use it outside in the summer when reading books in the sun. Otherwise I use my iPhone 13 Pro Max that is always with me. It’s a great ebook reader

[@Goldminks]

@@svartling would you say its worth keeping the Kobo E Reader or returning, primary function was for reading but the fact it doesn't sync notes with ibooks where i have alot of books makes it really inconvenient

[@svartling]

If you don’t read much outside in the sun then you don’t need an eReader.

[@nldgzq]

Maybe should disable "auto brightneess" or the brightness will change

[@svartling]

Yes of course. The brightness needs to always be at 100%. So that’s right

[@mahmoudelsaka9129]

Can i reduce white point without maximizing the brightness?? Cuz its take too much battry and i play alot of games

[@svartling]

No not with this method. To reduce PWM you need to have 100% brightness. Reduce whitepoint is only if the screen gets too bright with always 100% brightness.

[@Smart.Potato]

reduce white point does not decrease pwm. I tested this on my iPhone X with reduce white point at 99% and brightness 100% still when I record slow mo video of screen it still flickers ☹️

[@svartling]

At full brightness there is no PWM dimming so PWM flickering is not active then. And that's why you should reduce white point so you always can have full brightness. And I don't have PWM flickering on my iPhone XS Max with full brightness when recording screen with slo mo

[@JamesAutoDude]

@@svartling unfortunately there can be PWM even at 100% brightness. Just means it's a hardware/limitation problem and not a software/screen problem at that point

[@svartling]

@@JamesAutoDude not on iPhones. There is a lot of websites that has measured that. But most Samsung phones still has PWM flickering at 100%. And after I started using this method I don’t have headaches anymore thankfully. And some users in the comments says the same. So it definitely works and that is the main purpose

[@JB-sh1ho]

It still has flickering when reducing white point to 100% and brightness all they way up. If you film iPhone 12 in slo motion with another phone or tablet, you will see the flicker

[@svartling]

Very negligible because the PWM dimming technology should not kick in on 100% brightness because it doesn't need to dimm the display. It's so little that most people doesn't suffer from it. It's not until you lower the brightness that it gets too much to be a problem. And also, turn off auto brightness. I should have said that in the video. I forgot that.

Intressant Stefan, Samsung telefonerna har något som heter blue light filter eller på senaste modellerna eye comfort shield, vet inte om det är något liknande, men syftet är att förebygga produktionen av melatonin och förhindra eye strain.

[@svartling]

Ja blue light filter har funnits länge på iPhone också men det är tyvärr inte samma sak. Och dessutom kan det förvärra PWM flickering på oled skärmar. Så jag rekommenderar inte det. Utan full brightness och dark mode är det enda man kan göra på samsung telefoner tyvärr

[@saabfanaticnet]

@@svartling Aha, fick man lära sig nått nytt! Bra informativ video Stefan 👍

[@svartling]

Tack. Tyvärr så har de senaste samsung väldigt hög PWM flicker rate enligt oberoende test siter. Bland de högsta faktiskt. Fast bara under 100% brightness.

[@saabfanaticnet]

@@svartling Aj,aj. Får fläska på med 100% då!

[@svartling]

Och dark mode :) man kan enkelt se hur mycket PWM flicker en enhet har om man har en annan mobil som har slo mo (slow motion) inspelning på kameran. Då är det bara hålla den kameran ovanför den skärm man vill undersöka och ha slow mo läge på. Och då sänka brightness successivt på skärmen man testar. Helst på vit bakgrund. Jag gjorde det på både note 10 plus och iPhone xs Max och båda hade massor av PWM flickering 🙁

[@angelaziliotto2318]

Hi Stefan i have white point at 70% what does it do to my eyes? Please i tought that lightness impact my eyes and reduce the white point will benefit my eyes, how does it works? And how white point impact our eyes please?

[@svartling]

Reducing white point means that the white light is not so bright. The number should be as high as possible. 70% is too low.

[@angelaziliotto2318]

@@svartling thanks for your reply Stefan! But i always learn that more brightness = easy dry eyes and this effect drastically our view. My question is specific for every day use not just for reading sessions so i need to safe my eyes as better as possible. I don’t wanna stress it but i don’t know how to do it, i really wish you will help me 🙏❤️ (btw i use my phone 9-10 hours/day also for working on it)

[@svartling]

No more brightness from the white point hurt your eyes and they get tired and dry. You get headaches and more. So reduce whitepoint to not get that.

[@angelaziliotto2318]

@@svartling so 70% of white point for my daily use of 9-10hours/day is correct or not? Cause also with auto brightness the light will really often automatic set up to the top and this hurt my eyes, with 70% white point this “top brightness” produce a lower light and this, i think, keep my eyes safe and doesn’t stress it. Let me know if i miss something please 🙏

[@svartling]

As I show in the video, turn off auto brightness, set brightness to 100% and lower whitepoint to your need. It’s important to have brightness at 100%. Watch the video again.

[@hamzadrhimeur3253]

Hello, thanks for the video. I have a question which i find kind of strange. I bought a 13" e-reader with e ink display to read pdfs, but it gives eye strain and i can't focus on the screen after a while (20-30min). Although i have a galaxy phone with amoled display and it doesn't give me eye strain or headeches with the blue light filters and the brightness adjusments. I just thought the e ink would be perfect (no pwm and no blue light) but it's not. Do you have any kind of explanation ? Thanks again

[@svartling]

No I have no explanation to that. It should more or less be impossible because e-ink displays is like reading on paper. Are you sure it uses e-ink? Which model?

[@hamzadrhimeur3253]

@@svartling thanks for your quick reply. Yes i'm positive. The model is Onyx Boox Max Lumi; i was very surprised my self. It has front light also , so i don't know if that may be the problem. Or maybe i just didn't give my eyes enough time to get used to it. It's really confusing to feel more comfortable using a phone than an e ink tablet.

[@svartling]

Front light is like having a reading lamp when reading a book so still a mystery

[@yesanton]

I also have this with kindle. It's all the backlight. Try to switch it off completely.

[@svartling]

It doesn’t have backlight. It has front light and it works exactly as a reading lamp when reading physical books.

[@RealMikethedealer]

How do you do this on android?

[@svartling]

I don’t think you can. Maybe there is an app that can lower the white light?

[@RealMikethedealer]

​@@svartling Ah ok, thank you

[@RohitRoy-mu9it]

on the s20 fe, we get something knows as 'white balance'. There's a bar with cool and warm at the extreme ends. So going by your video, reducing the white point, means going to which end? Thanks in advance

[@svartling]

White balance is not the same sadly. It only has to do with cool or warmth colors. I have that on my note 10 plus too.

[@RohitRoy-mu9it]

@@svartling Oh that's unfortunate. Nevertheless the video was good and I appreciate the quick reply!

[@svartling]

👍🏻

[@RohitRoy-mu9it]

After fiddling with my s20fe, i found that under the vivid mode there is something knows as advanced settings. There are three bars for r,g and b values. If i reduce all the three to 0, will that be the equivalent of white point? { I thought so, because the description of white point is intensity of each individual colour... }

[@svartling]

Probably but I have no idea how you should set that. On the iPhone it’s automatic

[@sameersaini1064]

Please tell about android

[@svartling]

Same thing, always keep 100% brightness. It's the only solution against PWM. Then if you want to dim it you need to somehow lower the white point. Always use dark mode etc.

[@Jason-lu3rl]

Easier solution to guarantee no issues with PWM is buy an OLED phone with DC dimming. Oppo find x2 pro or find x3 pro can do this when you select low light flicker free option. May be more phones out there but much better than the above solution if you want to be free once and for all.

[@svartling]

Yeah if you only will use the phone for reading books that is an option. Otherwise not because then you have to use Android and that is a huge minus. And then again, if that’s the case it’s even better to buy a real ebook reader with an e-ink display.

[@Jason-lu3rl]

@@svartling yeah I really wish there was a way to have no pwm on the iphones as I much prefer iOS. Its more stable and better support. But have I tried the reduced white point and still get migraines and blurred vision it sucks. Hoping one day can enjoy an iphone again properly as not keen on using the 11 normal at this stage.

[@svartling]

It’s the 100% brightness that is the important, not reduced white point. Reduce white point only helps at night when you think the display is too bright. but I will see how much problems with PWM the iPhone 13 Pro Max has when it arrives.
