I've had the same experience. I keep a deep orange filter on my monitor all the time, and I noticed my eyes started hurting a lot when I forgot to turn the filter back on after I had temporarily disabled it. There is also some evidence that prolonged exposure to blue light is correlated with macular degeneration, but there's no conclusive evidence that it causes it.

I’ve been using f.lux for maybe 10 years on a fixed lower color temp. This is basically killing blues and renders everything pinkish. This has been a very good solution for my eye strain. Another very good one is to look at magic eye stereograms for 3-5 minutes a day

I tried using other people’s computer and the regular image is noticeably bothering my eyes.

I've never been able to see stereograms, and I'm pretty sure it's because my eyes are at slightly different roll angles from each other, due to a surgery when I was young. One of these days I should just try writing a program to decode them for me!

Eye convergence has always been marginal for me, and as I grow older it does tend to cause some mental strain when I'm tired. I haven't correlated that strain to blue light yet, though. I do use the blue light filter on my phone at night, though, and it does perhaps have a slightly positive psychological effect.

My eyes are sensitive to light (blue eyes are usually more sensitive) but the stereogram exercise is to exercise the eyes muscles. When we spend a lot of time reading off as screen close by we use a specific range. When looking at magic eye stereograms we are forced into a different mode and I found it helpful for myself. I could not see stereograms at first and had a hard time with a binocular microscope as well, the image would not converge into one. I first learned to use that (and I remember pulling one of the eyes from the side to make the two images converge into one and once converged I would let go the finger and let the eye muscles get used to the new position) then I struggled a couple of days with stereograms. After a day or two of trying I started to make the image pop up but would lose it quickly. After more exercises I could keep the image in focus and look change the gaze all over the image, stare at each corner, etc. When I managed to do that my eyes started to feel much better, the eye strain that had been bothering me for some months went away. The eye strain comes back when I spend too much time in front of the screen and looking at a few stereograms makes it go away. Not entirely sure if you had the same problem but I did hear a bunch of people healing eye strains with stereograms. It could possibly be a certain type of eye strain only. Hope you figure it out one day.

I've also started doing this recently and it helps a lot. The only time where it's a problem is when working with design/photography obviously. It's not a pleasant surprise when I turn it off and realize that colors are not that great.
