For me it was a process to learn what I was sensitive to. It all was working fine in the beginning and started to worsen over time.
I can remember that I had no noticable issues with my Macbook Pro ( first unibody version from 2009 ), then I added an iPhone 3Gs, the first iPad and so on.
I started to have symptoms in the office ( I am working in IT ) and was happy to conduct trainings where I did not need to sit in front of the screen all day long.
The worst thing was when I bought an Eizo screen in 2014 that was meant to be flicker free. That thing just roasted my eyes and I felt like looking into bright sun light or something. Had a lot of pain and I had no clue how to continue.
This is when it all started.
So I was buying a lot of different screens, sent them back to e.g. Amazon and finally settled with this Dell 2408 which uses CCFL and has a VA panel. Some time ago I was also sensitive to some Dell CCFL IPS panels but it seems that my eyes got more resilient.
I also needed to change all LED bulbs in our home and use halogen bulbs though out. Unfortunately they are not being imported anymore in the EU as you might know. So I might result for energy saving ones or buy some stock.
What also triggers me is flickering. I tried Intel, ATI and Nvidia cards, installed different Windows and Linux versions and came out with the following result now:
usable configs for me on the Dell 2408:
Windows: Windows 10 with NVidia graphics card on my desktop PC, Windows 10 with 2 Intel laptops from work (using DP )
Linux: Fedora 36 with Nvidia graphics card using Wayland ( Xorg flickers too much )
OSX: Mac Mini M1 with Linear ColorProfile from Xrite.
If the screen flickers I also have issues to focus on the letters and have a hard time reading.
What I noticed is that apps have their own dithering. So I cannot use Chrome or any Electron apps. Some terminal apps also create some flickering like tmux, neovim or zsh. I have no clue why but at least I came up with a setup on all platforms I can use.
