Use f.lux or an equivalent (most OS have their own implementation by now) that filters out the blue light at software/rendering level, it's not perfect but you do instantly feel the comfort it brings to your eyes. Been using f.lux for over 10 years and it also helps alot with going to sleep at night. When it's off your eyes/brain thinks that they are in daytime / broad daylight, when it's on I fall asleep 2 or 3 times faster than without.

The biggest problem I have with it is that everything looks so much worse that I just wind up turning it off all the time.

Is this so seriously a threat to vision that it's worth it? I don't have the sleeping issues with screens some people seem to report, so I wasn't really willing to commit to it over that.

Change the settings. What you should do is take a sheet of paper and put it next to your screen. Then match your screen's white to the sheet. It's only a bit less blue. There's no need to set everything dark orange.

Okay, but that's a trade-off, you're still getting a fair amount of blue light through in that case. How much less blue light do you want? What's optimal for minimizing eye damage if that's a significant risk?

You don't want to eliminate all blue from your life. Decreasing it is good enough. What's the point of making your computer screen red if the minute you step outside in the sun you lose any benefit?

Make sure you change it to the "Slow: Natural Timing" transition speed so the shift is gradual. The faster speeds (which I believe are default) are jarring and too easy to notice.

Also Alt + page up/down to adjust brightness without affecting colorshift.

The benefit of software such as f.lux and Gnome Nightlight is that they turn themselves on at night and off in the morning. It seems like the OP wants to remove blue light at all times, in which case should be handled through your monitor settings. A software solution would be unnecessary.
