I also believe that forward head posture and anxiety/trauma (increased sympathetic tone/reduced vagal tone) in causing my symptoms.

When I consistently do exercises for my vagus nerve (like singing) my strain disappears.

Also neck/eye muscle exercises help.

    Using Latanoprost, are you able to use all devices you classified "not safe" ?

    Dithering is not your problem nowadays?

      Absolutely. Sympathetic activation causes pupil dilation -> more light on the retina and more sensitivity from LED light.

          simplex yes. This is fantastic. But I start tolerate them after 2 days of using Latanoprost

              Great discovery 🙂
              I agree 100% with your thinking. Finding a device that doesn't give us problems but we can't perform a software upgrade is not a real solution but just postponing the problem.
              Did your symptoms include migraine or “only” eye strain?
              What is the name of the eye drops you are using? In Italy I got out “Xalatan” which is supposed to have a concentration of 0.005% latanoprost. Does it have the same concentration as your eye drops? How many drops and how many times a day do you use it? It will be hard to buy it because you need a prescription here..

              In the meantime I'm trying to work on the autonomic nervous system too, with the course “Prima Trust”.

                  Primal Trust is great. Their Instagram has a lot of free resources.

                  Also look if you are on Reddit look into r/somaticexperiencing. Also this: https://youtube.com/@painfreeyou and https://www.instagram.com/jonathanmead have been helpful resources for me!

                  I also do EFT (https://youtu.be/K6kq9N9Yp6E), trauma releasing exercises (TRE, check YouTube) and Yoga (for anterior pelvic tilt, forward head posture, general reduction of muscle tension)

                    This is all fascinating. Where is this diagram from?

                    I accidentally found that when I have my eyes dilated for an exam that I seem to be able to tolerate screens much better. This diagram seems at least somewhat connected to what is happening.

                        How are you measuring your IOP so frequently? Do you have a device at home?

                            I’ve noticed if my neck muscles are really relaxed I hardly have any of my normal issues with oled screens, I’ve been in 2 major car accidents one where I fractured 2 vertebrae in my neck so I always have neck pain and my muscles are always tense

                                Lauda89 I used 0.05 eyes drops the twice a day at the beginning and then onece a day

                                  What were/are your symptoms before you figured out this treatment? For me on OLED phones (and also LCD phones with later versions of iOS, what seems like any Windows 11 computer and late versions of Windows 10 etc.) I feel bad almost immediately (weird dizziness/nausea feeling, fullness in ear like it's clogged, body warmness, sometimes pain in shoulder and arm)

                                  Just curious because I know many people have varying symptoms here. Mine seem to be pretty severe in terms of how quickly they come on.

                                      ocean10

                                      1-10 min - severe eyes strain like I got sand in my eyes.

                                      10-30 min - slight dizziness, slight brain fog, blurry vision

                                          Zodios So, in your case the symptoms are 80% eyes 20% brain? Or something like that... In my case it is the opposite so the eye drops may not be working well. But anyway, as soon as I can buy it without a prescription I will let you know! 😉

                                              ocean10 I don't understand why the exact symptoms matter. The are always going to be different between individuals.

                                              Why not just start experimenting with the information presented here to see if it (at least somewhat) helps your specific symptoms. Take matters in your own hands 🙂

                                                Zodios The breakthrough came when I found this study:

                                                IOP reduction in a third of patients with OHT improved flicker sensitivity, however no improvement was observed in glaucoma patients

                                                Can you give a link for the study?

                                                    There are many interesting things here and your case has filled me with hope for the future. I too have been investigating many of the conditions you mentioned and am still on the journey to finding the reason for my sensitivity to OLED screens.

                                                    The IOP issue is interesting. In September, my ophthalmologist measured my eye pressure and it turned out that my pressure was about 21 mmHg, so in the upper limit.

                                                    Unfortunately, in my country latanoprost is also only available by prescription. Maybe the physiotherapist I've signed up with will help.

                                                        What was your IOP before taking the drops? Just about to retest my eyes as my last test had an IOP of 18/19
