I mostly use VS Code & IntelliJ for work. The best I've found to reduce my eyestrain was Solarized Light.
VS Code makes it very easy to try new themes, so I did. I found Quiet Light (built-in) quite nice, but when I tried to switch to some darker themes like Nord, I felt this kind of "shimmering" on the screen, accompanied with the all too familiar dizziness and eyestrain I see on the Mac (which I can't & don't use) while on Windows 10.
Here's what Nord looks like:
I wonder if the blue-gray in the Nord theme causes some sort of aggressive dithering on the BenQ GW2765HT 27-Inch 2560x1440 IPS Monitor (sRGB) I am using. For reference: Windows Version 20H2 Build 19042 using HP EliteBook 840 G6 with i7-8665CPU with Intel UHD Graphics 620 on driver 126.96.36.19993. This setup has been pretty comfortable, I get minor strain, but I am able to do a full days of work on it.
In general, light themes have been much better than dark ones for my strain. I wonder if this is related to the esophoria.
Has anyone seen anything like this?
