Called Night Shift, this new tool aims to cut down on eye strain and sleeplessness you might get when you're tucked into bed with your iPhone or iPad. According to Apple (and many scientists), the bright blue light emitted by your iOS devices during the evening hours can keep you awake later than you want.
With Night Shift, you should be able to stay up browsing Instagram or playing games and still fall asleep without much issue. Here's how to use it.
To turn on Night Shift, launch the Settings app then select Display & Brightness.
Select Night Shift to see all of your options. There's a switch to manually turn on the feature, or you can schedule it to run by toggling the Schedule switch and setting the time.
Using the slider, you can adjust how drastic the color change is, from Less Warm to More Warm. More Warm gives you a prominent orange-red hue, while Less Warm is a much more subtle orange effect.
The first few days when using the feature will undoubtedly feel unnatural, but as you adjust to the color change you begin to appreciate the subtle difference. Night Shift mode will support iPhones and iPads with 64-bit processors. That includes the iPad Pro, iPad Pro 9.7-inch, iPad Air, iPad Air 2, iPad Mini 2, iPad Mini 3, and iPhone 6 and newer.
