I have severe photosensitivity; large blocks of white hurt my eyes. I use userscripts with Tampermonkey to change sites like this one and Github to a dark color theme that my eyes will tolerate much better.
I think I might have the same thing tough if I reduce temperature I can tolerate white allright. It actually removes all the blues and starts to look pinkish. I use the f.lux app with a slight color temperature reduction at all times. Sometimes I accidentally turn it off and what a difference on my eyes!
