iOS 9.3 Night Shift mode iPhone.JPGAlex Heath / Tech Insider

Your iPhone's bright blue display doesn't have to hurt your eyes at night anymore.

Apple has introduced a new feature called Night Shift for the iPhone and iPad that automatically makes the display's color palette warmer once the sun sets. It's available for developers and public beta testers of iOS 9.3, an update that will be released for everyone to use in the coming weeks.

Night Shift mode is a set-it-and-forget-it kind of feature that could make using your device in the dark a lot easier on your eyes. Here's how to set it up.
