There is conclusive evidence that blue light does not affect sleep in any way as large as people expect. We're talking about 1 minute on average change in sleep duration.

Here is a simple search on real trials:

In my opinion:

The f.lux guy is intellectually dishonest. He's been at it long enough. He's got a lot of axes to grind. I don't see any trials in https://justgetflux.com/research.html.

f.lux use by normal people and other similar stuff is a good canary for how sophisticated a person is.

Many, many adults suffer from going to bed too early, not too late, especially older adults, a huge number, millions. People have been trying blue light as an intervention for them, and it doesn't work.

What do you mean by this?

Personally I find warmer colours easier on the eyes, especially in dark rooms. Nothing to do with sleep.

Sleep duration and sleep quality are different. Blue light definitely affects sleep quality, as your own link shows multiple studies that found this result. The causal association of blue light and sleep quality is pretty solid.

I want to live in a world where more people understand that 100 studies finding something still doesn't make it true...
