I have discovered something that maybe will make the one-eye-training better.

First a bit background. I started training with only one eye looking at the bad screens five years ago. When I started I couldn’t use any new screen. It took around two years before I could use every screen. I trained a lot the first year, less the second and then when I needed with the new screens that I had to adjust to. Today I use new screens 10-12 hours a day with both eyes, it just works. I usually patched my non-dominant eye.

Three months ago I ran into a new problem, Philips Hue lights. That kind of confirms that flickering is a problem. So I started doing what I have done since I could use every screen and then finds a new screen/device that I have to get used to. I train with the new screen/device for 30-60 minutes. Usually that’s enough, then I can use it.

But with the Philips Hue lights my training didn’t work. I tried like everything, which results in tension headache for a month. I continued training and it took almost three months before I found the solution.

The training didn’t worked when I have dimmed the lights. But with the light at 100% I got used to them in a moment. For me this feels like an important discovery. Does training works better with less flicker?

    mike it could also be that more brightness caused a need for habituation. I'm sure there are a ton of studies related to what modulates the habituation response.

    I've had a lot of hue lights. The different bulb generations are quite different, and the lightstrips are really bad. My main trigger with them were dim red light.

        Yeah, could be. The main point here is that I have had great success with my training. But many haven’t, could be that people have been training on screen/devices that gives different results.

              mike It's super interesting for sure. But did the habituation carry over to more dim light and different color lights? What type of symptoms?

              Also if this is the case, then what happens if you sit in a totally dark room with only that bulb for training?

              Would be interesting to hear what the reasoning is for patching the non-dominant eye. I don't know much about patching tbh, but isn't the opposite more common?

                  My theory is that training works with screens that use PWM, but not much at all with screens that use heavy temporal dithering. For example, one of my old Windows laptops has some mild PWM (but disabled dithering) and I can use it totally fine, and I can also tolerate my iPhone 14 Pro for basic phone use stuff at this point, especially outdoors (still get dizzy when trying to do more complex work on it though). Sometimes I just naturally/instinctively covered my right eye while using my iPhone which helps in that case.

                  However, on heavily temporally dithered LCD screens, trying to cover one eye doesn't seem to work at all for me and can actually make the screen feel worse at times, like I can't keep anything in focus.

                  And even before I learned what temporal dithering was, the longer and longer I used screens affected by it (without even knowing my pain was coming from the screen), I would just feel worse and worse. So it's not "adjustable to" in the same way that screens that only use PWM are IMO.

                  -

                  As a side note, I don't think I can adjust to PWM lightbulbs at all though. I mean, the house was lit by flickering LED bulbs for years, and before I even knew about PWM I would always be turning the lights on and off because I was always thinking they were "too harsh" or almost "too bright and too dim at the exact same time". It always felt like the lights "felt weird" in the house, no matter what I was doing.

                  I could never get used to those bulbs (which had 100% flicker depth at 120hz, ugh), even before I knew why.

                  After changing the house out to PWM-free Waveform bulbs, I've literally never had any issue with the lights at ALL since, I just leave them on constantly and they feel like the perfect level of brightness at all times!

                    When I adjusted to the lights, I could use them at 100% and dimmed without problems.

                    Because I had no problems with other things in the room I think is like a dark room.

                    Because that worked for me. It’s so simple. Why I don’t know, and I don’t know if someone on this forum really knows why.

                        @mike did you use patching when adjusting to the Philips Hue lights? Or did you just expose yourself to them with both eyes at 100% brightness until you got used to them?

                        A few months ago I bought Philips Hue Go, but after turning it on I immediately started to experience burning in my eyes, so I returned it. In general I've had a lot of success with Philips E27/E14 light bulbs (only one model caused noticeable eye strain) and most of them don't produce any symptoms for me.

                          Always patching when training/adjusting. But the training only worked when I had my Philips hue lights at 100%. After the training I could use the lights dimmed without patching!
