The Night Shift feature in iOS 9.3 lets you adjust the color temperature of the display, shifting away from blue spectrums of light, in the putative interest of improving sleep. But Apple makes no promises. On its website, 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.” In iOS, the feature is explained with “This may help you get a better night’s sleep.”
In fact, this feature likely will have little or no effect on most people. Apple hasn’t misrepresented any of the science, but clinical work done to date doesn’t point a finger right at mobile devices or even larger displays. Night Shift also can’t remove enough blue to make a difference if that color is the culprit. And blue light may not be the trigger it’s been identified as. While researchers haven’t tested the new feature yet, several factors add up to at best a placebo effect and a reminder to power yourself down.
I know people who enjoy Night Shift (and its Mac progenitor, F.lux) because they find it easier on their eyes at night. I think the stuff about getting a better night’s sleep is bunk, though. (And personally, I find the effect hideous — as though the display has been stained by years of exposure to nicotine.)
