madmozg Floaters in the eye could be an early sign of retina tear. If you have it through your life, and recently it has been getting worse (without external triggers) then it is better to seek an eye specialist. This is to rule out the danger of retina tear.

If retina tear(or detachment) is ruled out, then what you have experienced could be like mine, a migraine ocular. When I am exposed to bright lights, the floaters immediately come out. It is a sign that a migraine attack is coming soon if I do not something about the bright light quickly.

Floaters in the eye are a normal part of aging. Absolutely people should go for regular eye checkups, but floaters by themselves are not any cause for alarm. In fact, what often happens as people age, the vitreous jelly gets thinner, and the floaters fall to the bottom.

BloodyHell619 Maybe our problem is not gpu card but monitor. I play ps5 on tv make me eyestrain, so i play in my monitor and make me eyestrain too. But when i play ps5 on my steam deck via remoteplay, i dont fell eyestrain. Zero eyestrain. So maybe the problem is monitor/TV. I suspect backlight is the cause

    ludwig I'm not going to elaborate in detail seeing the depth of content that already exists on this forum, but there can be multiple causes for strain issues that analyzing and differentiating between them can be very difficult.

    ludwig No i think the remoteplay fix the problem. In my case, I am certain that the monitor itself is not a problem. I still have monitors from the early 2000s and if connected to a problematic PC they become unusable as well. And I am talking about monitors that I have used for over 10 years. I don't want to say that 100% of the monitors are okay but that is not the real problem.

    All the below answers are specific to my condition, but I believe apply to most people here

    1- Has anyone ever tried filming their pupils when looking at a bad screen with like a macro camera or something and compare it to when looking at a good scree? Surely, by seeing what is happing to our eyes themselves, we might at least be able to tell a bad screen right away. - The issue is not an eye problem, it's a brain problem. I've had more eye exams than you can count, including having an optometrist monitor them when looking at an offending screen. Nothing.

    2- My moms a doctor and even though she blames all my life problems on bad friends, my pc and the PlayStation which of course is her general term for every single console from the Super Nintendo to Xbox to PS5 and even though she is clueless about PWM and TD but among her diagnosis one was interesting. She said maybe my eye muscles have literally become so thick due to experiences these flickers for so many years that they just get easily burnt out. Has any of the doctors you've gone too ever had such a diagnosis. Again, the issue is a brain issue, cause by either trauma to the brain (car accident, injury) or genetic neurological condition I don't think a video game console would have any impact on anything

    3- I remember the first time I smoked weed everything in front of me started moving like in parties when there is a flashlight flickering, like I saw a bunch of still images. Has that ever happened to anyone when they've smoked? And have you ever felt smoking weed might have amplified your symptoms as it does increase focus. Never had that happen, and weed offered slight releif from the migraine pain once triggered, but not enough to make it worth the downside of weed

    4- Do any of you have high blood pressure, or diabetes or eczema and maybe found a relation between those and this pain that we get? Like taking pills for those making it easier to withstand these pains? No, but I have seen a very high correlation of people with sinus issues and out vision issues. I have only ever met one person who was cured of our condition and it was after he had unrelated palette surgery on the roof on his mouth. My theory if the nerve dysfunction at the root of all this runs through that area

    5- Have your symptoms gone away or weakened with age and with your eyesight becoming weaker or do they just keep getting worse? Gotten better with age. My neurologist believes I will eventually "age out" of this in my 60's

    6- Have any of you actually gone up to like official Nvidia and AMD stores and brought up the subject? I've talked to Apple, Microsoft, Google, and AMD about this. Even used some higher tier support channels due to access I get from work. They don't care. I will tell you now, you should not hold out any hope of them giving the slightest shit about us or fixing the issue. This number f people this impacts is less than a rounding error to them.

      ensete The issue is not an eye problem, it's a brain problem. I've had more eye exams than you can count, including having an optometrist monitor them when looking at an offending screen. Nothing.

      Okay, wait, wow that's bizarre! So you mean our eye muscles aren't making any rapid movements or such when looking at a bad screen, right ?? But then, how is it that our eyes themselves gets so horrifically strained?

        Yes they are, but is your brain telling them to do that. This is a visual processing disorder of the brain, not an eye problem

        I definitely think it’s a form of flicker at play, either caused by software or hardware.

        I’ve had a brain MRI which came back as normal, no signs of trauma present.

        Perhaps we’re “epilepsy lite”. However there must be millions of epileptics who are using new devices without issue, so that may not be a possibility.

        Many users on this forum have less than perfect Binocular Vision, and as there many successful patching stories it’s definitely one piece of the puzzle.

        I’m still confused as to why modern apps cause strain. Dithering on the app level shouldn’t be needed whatsoever if your display/GPU is set to the correct output.

        Also display technologies are much more sophisticated now than before. It all seems to have started since the switch to HDMI/Digital output. Back when CRT’s were the norm, the average computer display was 14-21 inch (4:3) and probably didn’t need parlour tricks to improve colour accuracy as CRT is as good as it can get, only recently OLed has caught up. The way CRT’s refreshed probably influenced the technology. As it’s a single line being drawn I doubt temporal dithering etc would have made sense.

        It’s hard to differentiate between software/hardware and a display when everything is in one device. That’s probably why so many assume it’s the monitors these days, when it’s more than likely the software/hardware displayed on the monitor. Not in all cases, but I’d be willing to bet quite a few.

          From what I remember photosensitive epilepsy is uncommon even among those with diagnosed epilepsy, and for what's it worth I am aware of multiple reports of people having seizures with the iPhone X series of devices implicated as the probable trigger.

          I use a very old Sony Vaio laptop with Windows 7 installed. I used a Cleaner software which cleaned register files and an antivirus who made some updates to the drivers or software. After that I can t stay in front of the screen anymore even if that s still an old LCD screen. But if I start the OS without drivers I have no eyestrain at all. So my issue and eyestrain has to see with something which happened with drivers/softwares, not hardware

          I feel my optical nerves are stretching while looking at the monitor. It takes one day to recover. So yes it has something to see with nerves and brain

            Clm Ok that's promising, if you're booting into safe mode and aren't having issues, then what you should try is using https://www.guru3d.com/files-details/display-driver-uninstaller-download.html in safe mode to 100% scrub the display driver from the system. I have used this before and it works well. After that's done, you can reboot normally and it'll be in the MS basic display driver. Then you can install a display driver of your choice, perhaps the one that originally came with the system.

              Unfortunately it didn t work, still experiencing same symptoms. Is that maybe related to other drivers or softwares?
