From Wikipedia, the free encyclopedia
Night Shift is a built in software feature of iOS and macOS. It was introduced into iOS in iOS 9.3 and into macOS in macOS Sierra 10.12.4. The feature changes the color temperature of the display towards the yellowish part of the color spectrum that reduces some of the blue light from the screen. Apple claims that the feature may help users have a better night's sleep by filtering blue wavelengths from the display. The effectiveness of this feature is disputed. The feature is similar to the functionality f.lux provides.
The feature can be turned on in Settings (in iOS) and in System Preferences (in macOS) and can be toggled on or off manually in the Notification Center (in macOS) or in the Control Center (in iOS). The feature can be enabled or disabled with Siri in iOS and macOS. The feature can set so it is enabled at sunset and turn off at sunrise (the default) or turned on and off on a custom schedule. The feature when set to enable at sunset and disable at sunrise relies on the user's approximate location to determine the time of sunset and sunrise. The user can also customize the intensity of Night Shift in Settings (iOS) or System Preferences (macOS).
