> Everybody wants better sleep

Bro, as someone who had brutal insomnia for a couple of years and now sleeps "normally" for whatever that means, I can tell you that I don't think about my sleep quality at all. I'm happy to be sleeping.

If you too sleep "ok" for whatever that means, maybe stop worrying about optimizing it and go do something else less insane.

What did you do to tackle your insomnia?

Waking up tired and with the brain full of fog is nearly as fun as not sleeping and ending up tired, with the brain full of fog. Truth be told, most cases of "poor sleep quality" are not as brutal though.

But have you considered that it feels better?

so do placebos

I agree for sleep. I prefer them because they focus better for me.

Blue creates a halo around letters that is distracting with my declining vision.

Also, Blue fluorescent OLED are ~50% less efficient than R/G phosphorescent OLED so you can reduce screen power consumption of a full white page by almost 30% using such a filter. That in turn might be 30% of active device power consumption (for a total of almost 10% in battery life during active operation). Ignoring that they also tend to burn out more quickly, since tandem blue has become fairly mainstream.

Many more reasons for these "filters", if you don't mind the white balance shift and reduced color gamut.

They absolutely help my eyes not be so strained. If its placebo, its a working placebo.

>Are people actually using Night Shift? >Aggravatingly, yes.

What is the authors problem lol? It feels a lot better on eyeballs to use warm light things. Why does he care?

Primary, idiopathic insomnia doesn't really exist. It's almost always anxiety, although a few other mental and physical conditions can also cause it. But more likely anxiety.
