Many studies have shown that exposure to bright blue light in the evening can affect your circadian rhythms and make it harder to fall asleep.
Apple’s new version of its mobile operating system, iOS 9.3, comes packed with a features called “Night Shift” and it aims to reduce eye strain when viewing your iPhone or iPad in the dark.
It’s also designed to get rid of that bright blue light emitted by your device at night that impacts your sleeping habits.
Night Shift uses your iOS device’s clock and geolocation to determine when it’s sunset in your location.
Then it automatically shifts the colors in your display to the warmer end of the spectrum, making it easier on your eyes.
In the morning, it returns the display to its regular settings.
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.
Quick Tip: You can also enable Night Shift by via Siri by saying “Enable Night Shift“
