I have light sensitive eyes . The light amount that works for average people is hurtful for me . No correlated illness . I have a 13 years old samsung laptop that works good for me . The laptop is so old it is breaking totally . I need a new laptop or a screen . I tried a samsung book 4 and a lenovo and retourned them booth . I thinkered with the light , but to have a bereable light amount it was difficult to read .

Advice please on what to try . I am located in europe and the boox mira 13,3 is not avaible .

Thank you so muchin advance

I recently bought a Nothing 4a phone after my Samsung 34a clapped out with the recent heat wave. I've been using this phone for a good 5 or so days now and it's just been an assault on my eyes that continues even when I take hours away from it, even using my computer screen now is causing the same issue when it didn't before so it's having that lasting of an effect.

I know I'll probably need to return it but I don't want to buy another phone yet and go through the same hassle. What is it about the 34a screen that was safe to me that isn't on the 4a? I've read up about PWM but I understand the 34a is much lower so in theory it should be better but I also heard that there are other factors that can play into it but I'm not well versed enough in this realm, so what is the factor at play here do you think?

Just to note I have tried all the accessibility options, extra dim, etc.

added monitor advice in the end*

Hi everyone,

I suffer from severe eye strain . I am looking for a monitor that is competely safe for eyes.

The OS is Windows 10 Pro 22H2

Here is what I strictly need:

• Resolution & Speed: 1440p, 144Hz or higher (Powered by RTX 4060).
• Backlight: True DC Dimming ONLY (Absolutely zero PWM at any brightness level).
• Color Depth: True hardware 8-bit. Strictly NO FRC (Temporal Dithering).
• Phosphor Type: Standard sRGB gamut using YAG phosphor. Absolutely NO KSF phosphor (I am highly sensitive to red phosphor decay/smearing).
• Panel Type: IPS(preferably not fastIPS) or TN or VA. (I do not have an idea whether TN and VA is a good choice)

I want to avoid artificial signal processing, dynamic contrast, or wide-color gamut tricks as much as possible. Does anyone know of any specific models (even slightly older ones from a few years ago) that fit this exact criteria?

Thanks in advance!

I found something guys.

 Viewsonic Omni XG2431

24" + 1080p + true 8bit + YAG (no ksf) + no PWM(Close purexp feature)

I am just so confused. I've been using the S23 for years never had any issue in my life. Then I bought a new phone and it all went wrong from there. I tried Pixel phones, OnePlus phones (12, 12R, 15R), Fairphone, iPhones, S25, all give headache and eyestrain within minutes. But the OLED in the S23 is perfectly fine even after an hour.

The LCD in my Xiaomi pad 6 is also perfectly fine for more than an hour. However the LCD in the Motorola G75 gives headache within minutes again.

The LCD in PC monitors are fine as well.

It can't be PWM dimming right? Then the LCD would have been fine.

Could anyone guess what the problem is?

[Edit: success vs PWM & flicker!] I wanted to say more than just cross-posting this post by u/xrmttf. Here's their body text (and my follow-up after):

>I'm not a spokesperson or influencer, I just want to post and say that these glasses completely changed my life. I have severe sensitivity to LED lights and pulsing screens and stuff, beyond the normal frequency that people notice. I had a whole neurological work up because I thought I had a seizure disorder but I think it's just autism+ haha. With these glasses I can actually live like a normal human pretty much.

>They're really expensive but you have 2 months to try them out. My personal experience as a careless person is that they hold up pretty well. F41 does nothing. Since I got avaluxe I can finally go back to college and get my degree, and I can go into businesses and restaurants with LED lighting, and I can go to my friend's houses again.

>You can also get the tint added to your normal glasses.

>Hope this helps somebody!

I've not looked into these filters previously. I'm surprised that they don't look more green(?) from this light spectrum graph (from the Avulux website):

https://preview.redd.it/54lbj6j27pah1.jpg?width=843&format=pjpg&auto=webp&s=69165adc522d43411217d0f4058ed2b11ac25874

The light wavelengths they most strongly remove appear to be exactly the peak sensitivity of melanopsin (480nm, cyan/turquoise) and the smaller KSF phosphor peak (600nm red/amber). But I guess the the maximum transmission envelope slopes down from red to (damaging) blue at about 50% blocked.

So anyway, would general success (vs PWM, etc) with these filters fly exactly contrary to my hypothesis of *too little* melanopic light from screens? See section 4 (malanopsin gap) of my big spectrometer post. Diagram from my post:

(Composite of Wikipedia images.)

My thinking being that too little melanopsin stimulation should lead to excessive pupil dilation and excess visible light wavelengths stressing cones, retina and the brain more... Also (in section 4b) contrast sensitivity and colour perception reduced, so increased with these glasses? Some other factors harder to fathom out.

Bonus question: does this filtering help avoid screen light delaying sleep onset? But then also reduce alertness in the morning and daytime, or potentially worsen depression/SAD? (Malanopsin stimulation produces dopamine and suppresses melatonin.)

The official theory behind why Avulux glasses help migraine sufferers comes from a paper I also referenced in my big spectrometer post (only green light doesn't exacerbate migraine):

>However, in a follow-up 2016 paper they demonstrated that rods and cones also mediate this pain, with isolated blue, red, and amber all problematic, but not green.

So, I'm curious for your perspective on the above questions, Avulus users. Including OP, u/DramaticKnight, u/Life_Tree_6568, u/DGG_DGG and any others. I understand xrmttf is not sensitive to daylight and this is a bit of a surprise result? Although has autism and other issues with health?

I and some others here are not currently able to reply over on the PWM sub, for unclear reasons (see the latest pinned post for context). So one of you is welcome to add a comment on your original post, to link back to here, on our behalves, please. If you see fit.

I tested a 6+2 FRC monitor (Sunvision 32" RLCD) using a 6‑bit‑forcing EDID emulator and compared behavior with and without it.

With 6‑bit EDID emulator:
Windows reports 6‑bit color depth. If I use ditherig to disable all dithering, I see clear banding in gradients. If I enable spatial dithering using ditherig, the banding disappears.

This is with the emulator forcing 6‑bit and dithering disabled (visible banding):

https://preview.redd.it/o4mvvzuvkoah1.jpg?width=960&format=pjpg&auto=webp&s=f2a0b471ab9119e725765dc4a5f525da629f4f47

I’m assuming this is roughly what a “true” 6‑bit signal should look like — for those familiar with native 6‑bit panels, does this level of banding seem appropriate, or would you expect more severe banding than in this photo?

Without EDID emulator:
Windows reports 8‑bit color depth. Even with all dithering disabled using ditherig, there is no banding. Enabling spatial dithering on top of that does not change the visible result; gradients remain smooth.

https://preview.redd.it/qjai4a41loah1.jpg?width=960&format=pjpg&auto=webp&s=1b328a7865603f004c4ca60ccd61f987706336d8

This is without the EDID emulator (default 8‑bit, dithering off, no banding):

From this, it looks like:

• When the link is forced to 6‑bit, the monitor behaves more like a native 6‑bit path and appears to reduce or disable its internal FRC.
• When the link is 8‑bit, the monitor keeps its FRC active, so even with GPU‑side dithering disabled, the panel’s own temporal processing still smooths out gradients.

So in this setup, a 6‑bit link seems to tell the monitor to back off its FRC, whereas an 8‑bit link keeps FRC engaged. Not sure if all monitors behave this way, but this is what I observed on the Sunvision 32" RLCD. Would be interested to hear if others have seen similar or different behavior on their displays.

The program used "Ditherig" can be found here: https://kawamoto.no-ip.org/henteko/myapp.html#ditherig

6-Bit forcing EDID can be found here: https://drive.proton.me/urls/813M4R3WS4#FPcBbRXqyK9q
Technically you can modify the EDID to add more resolutions and refresh rates.

EDID hdmi emulator I used: https://amzn.to/4vL0Hjw

The one I ordered from the first link has write capabilities enabled so I was able to write the EDID above onto it directly.

I am getting sick of just using phones with LCD screens, and from those, I have to choose the ones with Snapdragon chip because mediatek causes eye strain (My theory is that miravision is the cause) but life would be so much easier if i could just buy a phone with an oled screen that dims the screen in a different way than pwm. Ive tried high refresj (something like 3,800 hz) but it doesnt work for me. Only phones that work so much better are motorola phones with its dc like dimming, but still, “Flicker is flicker” I hope Apple does full dc to their screen somewhat or samsung and then every other company copies them. If they make a good midranger and a flagship, they would have somethin between 5 and 10% of all the population that uses smartphones buying their phone but why is full dc hard to make???

This is honestly a cry for help because idk what do anymore. The biggest issue is I feel like I will lose my job eventually. In January 2026 I started getting really bad light sensitivity and blurry vision/ trouble reading blocks of text on my computer. I took 4 weeks off work and things slowly started to get better except the light sensitivity. I begged for a neurologist referral and after being declined 3 times I got one. I went to see her and was diagnosed with migraines (even though I don’t get classic migraines ever). My light sensitivity was so bad when I would work on my computer I would ball my eyes out all day because the pain was unbearable. I had panic attacks everyday, woke up and immediately went to throw up because I was so anxious, etc. I was prescribed medication and the pain/ sensitivity eventually started to go down. Just when I thought things were getting better about 4 weeks ago one day my vision started to go really blurry on the computer again but also when reading anything off the computer, menus, grocery store items, etc. I went to every doctor/ specialist possible and no one can see anything wrong. I have been off work again for 4 weeks and this time my vision has not gotten better and feels like it is getting worse. I work an all day computer job and just being on my phone for 10 minutes is near impossible. I have run out of people to see/ talk to and am feeling really hopeless. If anyone has any experience or ideas please let me know.

Hi! I apologize if this has been discussed before. Its very hard for me to go through subreddits past post when I have a headache. Which is kind of why I'm here. I have extreme light sensitivity, the glare on the page from the over head light hurts my eyes. It's okay if it's outside in the shade or the little amber book light (sometimes).

Bc of this light sensitivity I cannot do anything that involves of a normal screen. Tv, computer, games, you name it. My phone has a ton of settings on it so I can use it.

My question is has anyone in this sub had similar sensitivity and had luck with e readers? I miss reading, I miss falling into a book. We're also expecting our first child this year and I've seen so many moms mention their kindle being a life saver during breastfeeding.

I see a lot of older kindle paper whites on marketplace and I have considered grabbing one. If anyone has a recommendation or similar experience I'd love to hear it. Thank you<3

I am both pwm and TD sensitive. I have used it for 1 day so far. I did all altering to become easy on eyes. I closed g-sync on Nvdia control panel. altough everything , I feel pain . What is the problem any ideas?

I have Windows10

Dell s2725dsm

*No PWM

*No FRC

*It has YAG type (not KSF)

I need some advice on work place arrangements please.

I've got a sensitivity to screens due to temporal dithering and sensory processing disorder. I'm also diagnosed partially sighted and have strong records that show I have adhd and autism.

I had a pc that worked for me for years and due to updates I'm no longer able to use the screen. My work have also said I need to hand my laptop in but they are using blanket term security as a reason. This security reason wasn't given before. It was previously life cycle reasons and the lease expiring and mainly standardisation. They know due to my struggles I've found it very difficult to find screens that work.

They have made appointments with occ health for them to come over and do a test on a screen that I explained already is very painful compared to my original. They are saying they need to use the new one and not the original.. But they aren't including me in any of the meetings about this. I'm just getting told last minute what equipment they want me to use even if it is painful.

I feel that this is really unfair and they haven't been very collaborative in the process. The person telling me the details isnt It trained either so when I'm asking questions they aren't able to answer me and we go round in circles without giving solid reasons. I do feel that the word security is getting thrown around as a blanket term without good justification.

Has anyone got any advice please?

1. Has anyone confirmed no dithering on EU / UK units

2. Does anyone know if it's possible to really dull down the screen, reducing the RGB values on my monitor almost completely got rid of symptoms for me, so some of the settings I've seen on this phone look promising

Cheers
