Ive been 'addicted' to the computer/tv since I was 1 years old apparently.
I dont find myself affected by any of these blue or yellow lights. I tried making the change and thought it was easier on my eyes, but I didnt feel different.
I'd be lying if I said I had felt this has a measurable effect on my well being, but such things are hard to measure anecdotally. I have personally never liked the software that adjusts computer screen display white balance over the course of a day though.
Or, shorter: maybe it’s because you have large east-facing exposure in your house.
Easier on the eyes is still something of a feeling, even if you perhaps don't prize it that much.
My impression is that a) the effects vary from person to person with individual preferences/different lifestyles and environments, and b) they are subtle effects to begin with.
I think it is telling that many of the more prominent examples here are from Seattle, which has several months of weaker access to sunlight (due to overcast/cloudy skies, northern exposure, etc), and we know people there tend to have additional difficulty with things like Seasonal Affected Disorder. So the effects may be more pronounced and obvious in such an environment. As with all such things, your own mileage may vary.
I've been programming my systems and my Hue lights to take this sort of stuff into account, and while I'm not sure I see strong benefits day-to-day, every little bit seems to add up/help. There are certainly days when I come home from the fluorescent light lit multi-screen office I work in and feel subtly more relaxed by the dimmer and redder palette I use in the evenings at home. Maybe some of that is placebo effect, but certainly if it makes me happy, it's a worthwhile tool, even if it is just a placebo effect. Certainly it is subtle enough that I don't think about it most days, individually, but I feel like in the long term it does add up.
Similarly, studies have shown that those who think they've completely adapted to noise at night in high traffic areas, say, are actually being harmed.
Remember, these effects are comparable to jet-lag and spread out over weeks, they aren't simply immediate effects.
And I admit to extreme privilege in this regard. My sleep rhythm has an incredible amount of predictability and I'm usually asleep inside 10 minutes of getting into bed.
