  • Konjunktivitis Sicca/Sicca Symptomatik

hey guys. Today I was at the Neuro-ophthalmology at the state hospital in my hometown.

To be short. Eyes are ok. Just shortsightedness and astigmatism, but nothing new and everything is ok with my optic nerve.

But there is something the doctors mentionend. However this fact is very difficult to explain in english for me, but I try.

They sad the the "grease film?" in my eyes is not ok and some lachrymal glands are not working correctly. So Konjunktivitis Sicca/Sicca Symptomatik means "just" dry eyes. But they mean that this symptomatik can really cause the heavy issues I'm suffering from. Now I should try out some eye ointment and eyedrops as well as an special eye lid massage (which is very important for my lachrymal glands to work correctly). I also know that this won't help all of us and do not bring us really forward. The also said that it will take some weeks/months till the special lachrymal glands will work correctly and the massage helps.

Of course this problem will explain something. Cause different new picture enhancements like dithering and anti aliasing are more stressful for the eyes and after a certain threshold the bad eyestrain begins. Also Sony TV is more straining my eyes than Samsung TV. Searching for the technical background is a running the gauntlet which I'm doing for nearly two years now.

I also hoped that the doctors will find something more convincing. But they insist that this is the problem and that this tiny not working lachrymal glands can cause this obscure problems.

Only thing I can check in addition to that is strabismus.

Well also if this diagnosis is really the problem, life will get much easier if the therapy helps. Cause if we ever find a technical reason for the eyestrain, what should we do? Searching for a fix which will work only under some perticular cirumstances?

    Harrison Interesting. I'm having MRI's and eye exams done soon. Have had small optic nerve since birth (obviously)

    Good luck!

      I should mention I use a 2013 Samsung smart TV with no problems, have disabled all the post-processing functionality. Don't have the model number on hand.

        Now I understand why Apple says that they want higher contrast ratio and vivid display... They wanna ruin our eyes !!

        Joke

          JTL Well my brother has also a Samsung Smart TV 2013. I also don't have problems with it. I tried out Samsung Smart TV 2014 -> eyestrain, but not as bad as Sony etc.

            Interesting to note. I will find model number of mine later, tested for PWM and none at settings I use, then again with TV's you mainly just set it up once and forget about it unlike laptop displays/desktop monitors, etc.

              JTL Yeah your model number will be really interesting for me. Moreover my brother never disabled some picture enhancements, etc. all options are on default settings.

                  Harrison I will try and get you the information and maybe some pictures of the settings menus and how they are setup as soon as possible.

                  I had a bad migraine today (yesterday), was rapidly shifting eyes from paper to screen, room lighting was uneven, eventually my eyes got strained and I started seeing red and blue (before migraine). I took two of my Axert pills and that cleared the migraine within 10 minutes but it causes severe insomnia in me (currently 2 am here)

                  Ah well I have this time to work on school reports and that like.

                  😐

                    Harrison changed the title to Konjunktivitis Sicca/Sicca Symptomatik .

                    Cause if we ever find a technical reason for the eyestrain, what should we do? Searching for a fix which will work only under some perticular cirumstances?

                    What it needs is its own name, something more descriptive then "eye strain".
                    There's already a variety of fixes. Avoiding PWM or getting ones with extremely high frequency
                    Changing graphics cards or some such for temporal dithering
                    eliminating blue light..

                    problem is much of it is scattered and un-verified, going off of a single account saying "I think it's better". It's also difficult to identify which is causing what and of overlap.

                    There was some talk of organizing this info and a few ideas were presented. I can have a wiki installed, utilize a wordpress page, utilize this forum, utilize other places (like wikipedia)

                      Slacor Wikipedia would be wrong place IMO. WordPress and MediaWiki are the bestidea

                        Slacor
                        yeah thats right. But the problem is that not all of us are suffering from the same problems. Nearly all of us mentionend different issues and problems in our welcome area.
                        But we need a word different than the harmless "eye strain".

                        Well of course there are some fixes and ideas. But there's always: ....this works for me, but not for others....

                        Also I think currently that the theories about PWM are'nt right. More precisely I think that PWM is not the only reason for the problems.

                        You meant that there's already a variety of fixes. I don't think so. Nearly all your mentioned points are at most just ideas and assumptions. There was never a person who said: ....this was my problem and after this fix I haven't any eyestrain and headache any more.

                        Hm. Good Idea with the wiki. I think an overview of our ideas and theories would be very interesting and helpful for people. Why not just adding this to this website?

                        Well the greatest problem is getting information from manufacturers. Let's say temporal dithering is really the problem. Than we have to ask the question which kind of dithering is ok and which kind of dithering is harmful for us. Same on the PWM side. I hope you understand what I mean.

                          I still don't have answers to basic questions like

                          1) Temporal dithering from driver
                          2) Temporal dithering from display (FRC)
                          3) 1 + 2 = ?
                          4) Just 1 or just 2

                          A lot of this could be solved with access to varying hardware, switching out various components and perceiving different results.. Unfortunately, doing so will cost a small fortune :\ Then there's different people with varying issues... hmm.
                          As for sites, I have a mediawiki installed at http://wiki.xyzz.work
                          I haven't done much with it and I might move it to something like info.ledstrain.org or something.

                            JTL haha
                            I needed a generic domain that I could use as a backend for other domains/sites.
                            .work tld is like $3.5/yr and xyzz is very easy to remember and is pretty much as generic as you can get 😃
