madmozg It's perfect. I have yet to leave the screen from strain at any point since I got it. That doesn't mean I never get mild upticks in migraine like symptoms or slight glow on high contrast text, but never to an extent where it interferes with wanting to sit there or get work done.
I still have a hard cut where I don't ever research eye strain or similar stuff while using it, or change any settings. As there is no doubt a psychological component to a lot of this, as well as learning to ignore things I do think that helps as well. I switched the bulbs around my workstation to old incandescent bulbs and put in a heated foot massager. Everything to create a space where there is as little discomfort and stress as possible. Rewiring neurons takes time, and finding a way to spend time with a screen while keeping dopamine high and cortisol low does for me seem like a reasonable target.
I still get insanely tired if I have some excessively flickering led in my peripheral vision, and I get way more symptoms if my neck locks up, eats something that bloat my gut, or consumes B6. Nitrites, perfume and dehydration are also noticeable. Also I almost never use my miniled Macbook, as the screen is utter garbage compared to the XDR. However when I do I keep the exact same PPI, as I think frequent readaption could be an issue. Also my contact lens adjustment seems to help.
Super happy that this one works, and for now it seems like everything is moving in a positive direction. I'm starting to get a better feel of how everything fits together. For many here I do think it is critical to get both the internal (health/body) and external (screen/lights) factors that contributes to hyperexcitability down below a threshold where it is possible to actually get used to screens again, and to forget about them ever causing issues.
