In Night Shift’s version of color adjustment, there is still a significant amount of blue light present.

Night Shift’s blue light reduction levels A color intensity chart shows that Night Shift barely reduces the blue light levels right before a user’s typical bedtime. In the morning it returns the display to its regular settings.Īccording to f.lux, the problem with Night Shift’s implementation is that they are not reducing the blue light levels enough. It then automatically shifts the colors in your display to the warmer end of the spectrum. Night Shift uses your computer’s clock and geolocation to determine when it’s sunset in your location. 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 the post shared today, a member of the f.lux team shared some data to show why. While at first glance it appeared Apple’s take on adjusting the display’s color and lighting would ‘ sherlock‘ f.lux, that doesn’t appear to be the case. Specifically, lowering the output of blue light from a digital display to help make it easier for your body to fall back into a natural circadian rhythm.

The general idea behind both systems is to alter the colors your display is outputting. Night Shift is Apple’s answer to the f.lux app. Both systems set out to enhance your sleep cycle by reducing blue light appearances on-screen, but f.lux may be the option that truly succeeds. In a new post shared on f.lux’s forum, a member of the team broke down why f.lux may be the better option over Apple’s similar offering.

Released yesterday with the macOS 10.12.4 update, Apple’s Night Shift may not be having the impact on your display that it aims to.
