I just bought Viewsonic VG 2240 which is flicker free, has low blue light mode and the most important: it is 8 true bit panel!!! It is connected to RX 6500XT which outputs also 8 bits. According to my knowledges, there should not be amy dithering in my case. Also using Benicci blue light glasses . After a few days i feel better but still, in testing phase…
Except temporal dithering, the operating system's display technology will also cause eyestrain. Try Ubuntu, I'm using it, and didn't have eyestrain symptoms.
I recall B2 helped my screen induced migraines, though I did not persist in taking it due to side effects.
How are folks thinking about handling this? Stocking up on a lifetime supply of incandescents?

I have compiled data on every smartphone I have tried, both good and bad, and so far I have been unable to find anything the ones that work for me all have in common. Screen type, color depth, CPU, GPU, DPI, OS, nothing. It is pure hit or miss
I will also recommend trying Skinomi screen protectors, for some unknown reason, in multiple instances, I have been able to turn a completely unusable phone into a perfectly usable phone (as in used daily for years with zero symptoms) by applying a Skinomi screen protector. I use the clear ones. In cases where Skinomi doesn't make on for the model phone I ordered one for a larger phone and cut it down to size to fit the screen
In one other case going into the developer settings and setting the Color Correction to Blue-Yellow eliminated the symptoms
I currently use a TCL A30 that was unusable when first tried but a Skinomi eliminated all symptoms.

I also recall some members of this forum having a theory that their problem is polarized light.
If that really is their issue, OP's mod would certainly solve that.- Edited
So changing from LED-backlight to sunlight won’t do it
Well, we can't be sure of much, because in-depth experiences with ambient-lit screens, outside of E-ink, are basically non-existent on this forum and nearly the whole web.
The transformation of direct light into indirect light could render dithering a non-issue in a similar fashion to how some people report having issues with flickering on LED displays, but no problem with flickering on CCFL or even 75+Hz CRT displays.- Edited
Update 1

Hello,
Since 2015 I've been dissasembling monitors I've been using. Disassembly is pretty straightforward - there are screws, clips.
LCD Panel consists of LCD Matrix, polarizing films, and light dispersing glass. Without polarizing films LCD Matrix will be a bit transparent, so it's required. LCD Panel can be opened using fingers, there are small clips, maybe also some tape.
There's a wire going from LED Backlight to controller board, it can be disconnected by hand.
Don't worry about strips that connect LCD Matrix to it's driver - they are sturdy. Most brittle part is LCD Matrix.
After opening LCD Panel like a book I used books, DVD cases, laptop box - so it would stay open.
Right now I'm using laptop with dissasembled LCD Panel. It's held open by a pen. During the day I use sunlight as backlight, and when it gets dark I use 60 Watt Incandescent lightbulb.
This is the ultimate solution and it will work for all of you. You won't feel anymore like there are bloody drills trying to drill your brain out of your skull. All the pain and suffering will be gone.
This is my experience.
If you have any questions I'll try to answer them to the best of my ability.
Regards, Denys Petiukov.
- In VGA cables
One factor that could apply is that VGA is an analog signal, and because of that the thicker the wire gauge could mean less signal loss. I think someone mentioned this is important for eyestrain somewhere else.

kamrangojira Welcome!
Your writing has a lot of capitalization which can come across as yelling.
To allow your writing to be easier to read, please write it in title case or lowercase.kamrangojira from this experiment i used a transparent PAPER COVER and taped it to my laptop screen
I will say, tinting got mentioned over here and it has been very helpful for my car dashboard's PWM.
I ended up using 2 layers of 80% dark tint (96% blocked I think) which works great at night and the PWM is going.Could it be your own car's dashboard? I put yellow film over the shitty blue flickery LED-based dashboard in my Fusion Hybrid, and turn the intensity WAAAAY down, and still occasionally find my eyes very tired and will move my hands to 11:30/12:30 in order to mostly cover the dash for a few minutes, which makes them relax.
Monte In reading your post (before you said you tried eye-tracking stuff), I really was thinking "binocular vision issues" the whole time. The give-away was that you have problem with print. That rules out a lot of things.
Try reading stuff outside in natural light to rule out even more stuff as your litmus test. Weird suggestion, but have you tried patching one eye? Maybe you have no problems with convergence, what about accommodation?
I say stick with the vision therapy exercises. Maybe even get yourself a Brock String. I'm pretty sure years of vision therapy really helped me. I still do 15-minute maintenance exercises on Saturdays and Sundays. I haven't really looked at this forum for the past 5 months or so, because honestly, I haven't had any visual comfort issues for a while.
Also always remember to give your eyes a break every 20 minutes and look at a distance object at least 20 feet away for at least 20 seconds. This makes a surprisingly big difference! Don't forget!
These are pain/pressure behind my right eye that feels exactly the same as the LED-migraine pain.
You described the trigger symptom perfectly in my own case as well. Looking at one of my colleague's LED monitors for about 1 minute will trigger an awful ache/pinching behind my eyes, but much stronger in the right eye. I've never dealt with migraines in the traditional sense before, but I've always heard of them being one-sided.
It was a while ago, but someone once did a play-on-words and turned the word "migraine" into "eyegrain", lol! I like it! Honestly it describes the issue a lot better, haha!
My only solution has been total avoidance of LEDs. I've gone about a good 5-month stretch without any big problems with eye/headache. I wish I had a better solution, but I haven't found one yet =(

Hi all,
I am a 41 year IT worker and found this forum after doing research into my own eye strain issue which has gradually worsened over the past few years to life ruining proportions.
I have always had a sensitivity to brightly light monitors. Back in the CRT days bright work place screens would give me extreme eye strain and nauseating eye fatigue but happily I used to find that a radiation filter would solve the issue. Other than that throughout my twenties and early thirties I had no other problems.
My problem grew more serious as I reached my late thirties. First I began to get severe eye strain from handheld screens (which I had previously been fine with). I found blue light blocking glasses solved the issue for a while but as time passed the problem worsened again to the point where they no longer helped. Ive gotten to the stage where any near focal activity gives me horrible incapacitating eye strain, even reading paper books. As I turned 40 the problem worsened even further to the point where my distance vision got affected as well. I now struggle even with watching TV, especially if there are moving images.
At this point in time I live with almost permanent eye strain with it getting worse all the time. While my symptoms are similar to many people here there are some differences maybe. I am affected by any brightly lit screen (but can generally solve this with blue blockers or flux. The real killer for me is that moving images are physically painful. Any eye movement activity (such as reading a book) is uncomfortable. For this aspect of my condition I have absolutely no answers at all sadly.
I have invested a great deal of time and money into finding solutions with no success at all so far. I have been to well over a dozen different opticians and they have all concluded that my eyes are normal and healthy.
I have been to two different private eye surgeons who checked my eye function (normal), performed an MRI scan of brain and eye sockets (normal) and ran blood tests for thyroid imbalances (normal) before telling they couldn’t help me.
I then paid for a private orthoptist to look at eye teaming, binocular function and eye muscle related issues. After a great many tests nothing was found wrong and I was given a variety of different eye exercises to help strengthen and improve my vision. Again no real improvement.
Finally, out of desperation I paid a small fortune for a London Harley street expert to examine me. After another set of eye examinations I was told that my eyes are fine and that all my symptoms are perfectly normal for a person of my age. Given I am physically incapable of playing a video game or even reading a book without severe almost incapacitating eye strain this conclusion seemed more than a little strange to me. I was told that I can’t expect to have the eyes of a 20 year old and was prescribed Amitriptilyne to help me cope with the pain. Apparently, taking a low dose of anti depressant as a pain killer for the rest of my life was the best London’s finest had for me.
So that’s my story. I have been gladdened (though also saddened) to find a community of people struggling with similar issues. Having been recently told by an optician that my issue is ‘in my head’ it has been comfort to find this forum.
I am not giving up. Currently doing a good 30 mins to an hour of eye tracking exercises a day in the hope that this helps (no significant impact yet) and continuing to read everything I can on eye strain in the hope of a break through.
I could easily write more about all the conditions an solutions I’ve tried and explored Myers Irlene colour glasses, prisms, vitamin supplements, anti inflammatories and more but that’s enough out of me.
I just hope we can one day find a solution.

randomboolean interesting. I have noticed with myself that lighting that usually gets into LED/CCFL 3200k and above I don't perform well. I use all Incandescent lights. I do have 5 halogens in my game room but all 20 Watts so they are less bright. I'm testing one LED 2700K flicker free in my game room right now. If it works I'm going to buy 3 more amber 2200k flicker free. I want more yellow light. I can tell you for me personally when a LED light hits the 3000k mark I can't use it.
I am sufferer too and recently had a chance to drive two different cars with in car screens - in between the steering wheel and at center console. I get instant symptoms. Not as bad as my experience with iphone 8, but I lose concentration and wouldn't call it a normal driving experience. Since even ford fiesta has a screen nowadays, I stress that "classics" will be the only way for us to drive around. Or we could modify our cars to have eink screens somehow.
Forgot to mention that I live in the US of A. I see lots of incandescent bulbs being sold on Amazon and still see them in stores. The community that I live in replaced the LEDs near my condo with CFLs. Amazingly, it has made a huge difference for me as long as I still wear eyeglasses that filter out blue light. Apparently, there is far less blue light radiation emanating from CFLs than LEDs and at least one medical study appearing on the NIH website obliquely confirms this.
I am doing OK with my desktop computer. I have a 24 inch monitor that is non-reflective and use f.lux software. Along with this I wear Rx computer eyeglasses that are tinted amber and filters out a significant amount of blue light. As such, I suspect I have a somewhat different issue than most of the people who are sharing on this forum.
For those who may not be aware, the next generation of light bulbs may indeed be incandescent. Scientists at MIT developed an incandescent bulb that has the potential to be three times more efficient than LEDS, reported over a year ago. I sure hope that these bulbs make an appearance on the market sooner than later. Please see: http://www.telegraph.co.uk/science/2016/03/12/return-of-incandescent-light-bulbs-as-mit-makes-them-more-effici/
