What is the best way to display dark mode for forums?

The last few days I often open forums at night, and it makes my eyes tired quickly when opening the forum in normal mode... Yes, my eyes look like this (@_@)

Why don't you use blue light blocking software as those are quite helpful when someone uses PC at night. Those have been helpful for me and I use blue light reduction most of the time. Also, I lower brightness of my monitor during night time.
