Did you get the glasses because you believed they would help your sleep, or for other reasons? One solution to why so many people talk about the improvements with Flux or glasses could be a simple placebo affect.

True, but placebo effect is random and uncorrelated with the change. Otherwise big pharma would just replace all drugs with sugar pills.

So for placebo you should also have a lot of people reporting that "greenish screen" helps, and you should have a green option in flux.

A few weeks ago I was advised by a lighting specialist that there’s a lot of ongoing disagreement regarding the best approach for reducing how light affects sleep. I was aware that there has been limited research and many of the solutions to this point have been basically “copy flux”.

Thanks for posting this. Very interesting read and has made me change my buying behaviour.

Is there disagreement also regarding the lighting level? I have dimmable lights and I like how I feel when I gradually dim them to darkness before going to sleep.

OK intuitively there is indirect and direct sunlight. Based on my highly unscientific personal experience I'd guess the body can tell between direct daylight and sunset spectra (both warm) and indirect daylight and twilight spectra (both cool). Electronic blue lights after lots of f.lux seem quite annoying, so I'd guess they are more like daylight.

Relatedly it always bugged me when I was little that blue lights seemed "white in the middle with turquoise then finally blue exterior". Blue lights just couldn't be both bright and saturated very easily. I wouldn't be surprised this is related to the daylight-ness vs twilight-ness.

Direct/indirect daylight is not warm, is cold:

> Daylight has a spectrum similar to that of a black body with a correlated color temperature of 6500 K
