Apple's Night Shift May Have Zero Effect On Sleep (macworld.com)

eggboard writes: While blue light emitted by monitors and mobile displays has been widely cited as a cause in disrupting people's circadian rhythm, the evidence is thin: a narrow range of blue spectra might not be the problem (it may be a more complicated interaction), brightness may be more important, and Night Shift's (and f.lux's) effects are probably too negligible anyway. Apple's Night Shift feature lets you adjust the color temperature of your display to the warmer end of the spectrum. Apple notes, "Many studies have shown that exposure to bright blue light in the evening can affect your circadian rhythms and make it harder to fall asleep."

It is good for some users

I have a friend who has to use light therapy every day. She can't view any screen for an hour or so before she goes to sleep. When she gets up in the morning she uses a blue enhanced light. She also has a lamp with a therapeutic spectrum at work. If she doesn't take these precautions then she has sleep problems and that causes migraine headaches. This is a real big deal for her.

I can easily see how this could be of use to some users. These problems are idiosyncratic, so it varies between individuals. Making a blanket statement that it of no use is basically willful ignorance. It makes a quick headline, and helps no one in the long run.

Sadly all we get in the west are those stupid Philips Hue bulbs that change to a variety of pointless colours.

Sadly, you have no idea what you are on about. Using the API, you can switch to any color you like, and you can get as complicated as you like with it. And F.Lux has support for controlling Phillips Hue, so you can have it happen automagically through that or other means. What a surprise that you of all people are talking bollocks.
