It may be a thing that the peripheral vision is better at detecting motion. I remember long ago, when I did not know anything about flicker, that I used to get very close to the screen and watch a grey backgound and detect into the very edges of the visual field what I thought it was the refresh rate (now I know it was PWM)

    Alyosha2001 Right, and some of us might have "peripheral vision sensors/receptors"(?) that are more sensitive than those in others.

      This is interesting, I am glad it works for you. It seems somewhat similar in spirit to "binasal occlusion" which is used in vision therapy:

        TBI was a big thing several years ago with football players, a couple of movies etc. surely we can get a doctor/ researcher to adopt us.

        mike I read about it here and meant to get one of those eye patches that you can stick on to glasses and give it a try but didn't get around to it.

            Deepdeep Just put a bit of paper on a pair of glasses and try it. For me it was a game changer.

                mike Nice to hear that it worked so well for you. I'll give it a go after I've messed around with the blinker approach with some other devices to see what it works for and doesn't work for … tricky stuff this!

                  ryans Thanks … I think I'll try these out just when friends finally stop talking about my blinkin blinkers!

                    Deepdeep Hi, thanks for suggesting blinkers. I'd like to note that I tried them and they didn't help me, unfortunately. 🙁

                      Hi, sorry to hear that it didn't help you. I'm getting mixed results with them so far - they seem to help for some devices and not, or not so much, for others - it might be that I'm sensitive to different things and the blinkers help with one of them. It'll be interesting to see how others respond to blinkers too. Thanks for your feedback 🙂

                      Found this video after seeing your post and searching more about binasal occlusion. This lady had pain watching tv and the binasal occlusion glasses (just tape on the inside of the glasses) helped her.

                      Have you tried this btw?

                        I think that, in some cases at least, the blinkers can help reduce symptoms (even if they don't eliminate them), and this can be helpful in increasing the time we can spend with a device or while we are trying to adapt to it.

                        With the idea that they maybe work by reducing the amount of flicker reaching our peripheral vision (which is more sensitive to flicker) I'm trying a further reduction by partly covering the lenses too. It seems to have improved the usability of the pwm-free Latitude 7390 without having to turn off font smoothing like I was doing earlier coz it helped. More testing required coz I've only tried it for a short time so far.

                        I've read before that peripheral vision is actually very important to our sight, it's what helps us appreciate distance and focus on further objects. So it could be wrong to block it in a long term fashion.

                          Liberator005 yes, probably a good idea not to overdo it. I felt a bit strange for a while when I reverted back to normal mode after doing it for maybe an hour though it was ok while I was doing it.
