It is an anecdote but I also much prefer redshifting all my displays. At this point, it is really uncomfortable to look at a blue screen on someone's phone. If the science isn't finding an effect, they are either not measuring the right thing or they are not measuring it with a large enough sample size.

I agree. https://github.com/jonls/redshift https://github.com/jonls/redshift has been a gamechanger to me. Hint for those with desktops: redshift may fail to detect your location so you can use -l lat:long to set it.

Is that only because it’s bright and contrasts strongly with the darkness? A dim one without a color filter looks fine to me.

  Well I always turn my monitors to the lowest brightness at night but when the program turns down the blue tones I assume it reduces the light output further. That may be the main effect that helps (brightness reduction) or it could be that reducing blue specifically helps. I’m not sure.

  True, but poorly designed studies and non-replicated results are also very common. I think if a majority of people find some effect to be anecdotally true I’m their own lives (“using flux makes my eyes hurt less and I fall asleep more easily”) then you should need to meet a high standard of very rigorous science to prove them wrong.

  Placebo is controlled for in these kinds of experiments by using a comparison group exposed to a carefully designed placebo. To be very clear, you can test for the abscence of an effect. It is a little bit more challenging than finding a "true" effect, but it is feasible. It is a dangerous, and common, misunderstanding to not distinguish between "no significant effect" and "statistically significant zero effect".
