With the new edition of iOS 9.3, Apple unveiled Night Shift. Night Shift adjusts the display colors to reduce the amount of blue light your device emits.

The idea is to help fight eyestrain and sleeping problems caused by that blue light.

To turn it on, go to settings, and then display and brightness. Tap Night Shift. From there, you can schedule times for it to turn on, manually enable it, or decide how warm you want the colors to be.
