MagnuM I think LED is the catalyst to our problem. Alexander Wunsch says it causes immediate damage and I think people like us are affected more quickly then normal people. Shiva I believe you can make your eyes a little stronger. Do you have a lot of exposure to flickering lights and LED and CFL everyday?

    jasonpicard Do you think after enough years of exposure, general everyday people are going to start having issues with macular degeneration after years of looking at LED displays? What if everyone else should be having the same pain that we do, as our eyes/brains/etc are telling us we shouldn't be looking at it!

      MagnuM

      There are a few reports from reliable sources (e.g. ANSE) that refer to the risk of macular degeneration after years of exposure to LEDs.
      My ophthalmologist says that I may be lucky in the end, she believes that chronic use of LEDs destroy the eyes, especially in children. However she says that we do not have sufficient research data to prove this.
      It seems people are the test animals in this case (LOL) !!!

      MagnuM I think it's only really a problem for people like us. Alexander Wunsch said in Germany that eye issues like macular degeneration have increased since LED has been introduced to Germany. My wife has been using a computer everyday for 12 years then comes home and uses her phone all the time and she doesn't even wear glasses. So I don't think it will be a world wide problem. We will have to learn to cope like we already have.

        jasonpicard Well maybe not in direct eye or retinal damage, but there's at least more support out there that too much blue light late at night disturbs important circadian rhythms.

          jasonpicard

          However, even if most people do not SENSE a problem, we can now see that monitor companies have introduced flicker-free and low blue light displays, blue light reduction software is now integrated in most devices as an option, companies producing lenses to protect from blue light have escalated their marketing effort and more and more medical professional discuss of the negative impact of leds (especially for children).

          I understand that there is some movement globally, otherwise why would companies take the effort and cost to do the above.

            Learning to cope or not, wiki page or wikipedia page will be of help. Sometimes you just need to annoy certain people long enough to get attention and response. I am not giving up. I am also not gonna be subject to work inability only because some OS decided to update itself without my permission and all of a sudden causes me migraines.
            So how about subliminal flicker sensitivity syndrome then? I can try starting it on regular wikipedia and see how that goes.
            There also MUST be a way to tell exactly what went different inbetween different versions of intel drivers. The intel thread is growing more and more. It just needs more pressure.

            • JTL replied to this.

              martin What about using a lossless capture card with the display output (i.e on a desktop) to check for any flickering frame by frame?

              https://ledstrain.org/d/322-capture-cards

              @AgentX20 is referring to something else, but I still suspect it's an interaction between possibly his GPU and the flight simulator software.

                JTL Definitely worth a try. The e-ink displays also show dithering, but capture card is the best lead we have. If we get something tangible, it might be something Intel can use.

                martin Nice initiative

                martin dont believe my problem is CVS, do you?

                I agree. Depending on the computer I am given at work I can stay 15 hours a day in front of the display without problem or go crazy after seconds.
                And headache is not really the main problem for me. That sounds a medium-term consequence.
                Sticky eyes, difficulties with eye mobility and change of focus / direction, cervical pain, loss of concentration, and various other psychological consequences...including anxiety from not understanding causes and not being able to identify solutions. And what about the burden of having to fight to find a smartphone or a laptop when everyone else just buys what he likes or what he can afford? I am so fed up of visiting stores or blindly purchasing items online to re-sell them half price. Not to mention hearing: have you tried to reduce the brightness? Or to take a break once in a while? Do not forget to breath :-(

                MagnuM I would suggest "LED Allergy" as a potential name

                I too called it allergy many times. I cannot think of a better term to describe how instantaneously my symptoms develop, similarly to pollen or grass allergy in spring when I was a kid. Seasonal allergy got way better for me over the years though, and without really taking medicines, but with electronics I have not seen any major improvement over the same span.

                Peter I understand that there is some movement globally, otherwise why would companies take the effort and cost to do the above.

                I hope so!
                I remember when I was told in 2013-2014 that it is impossible I feel flickering from flat panels because they DO NOT flicker. Then BenQ came out with the flicker-free monitors...
                What surprised me is that they did not really cost a fortune...maybe because, as you guys are saying, there are other factors coming into play, like what you plug the monitor to, so manufacturers could not really say to have solved the issue 100%?
