Your iPhone has a new feature to help you read at night - here's how to use it

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 as the sun sets. It's available in iOS 9.3, a software update Apple is releasing for everyone on Monday.

Plenty of scientific research has shown that it can be harmful to look at your smartphone's screen at night - doing so can negatively affect your sleep quality and cause even more serious health problems.

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.
