How to Enable Night Shift On iOS 9.3 to Reduce Eye Strain

Apple’s new version of its mobile operating system, iOS 9.3, comes packed with performance enhancements, bug fixes, and new features. One of the more touted features is dubbed “Night Shift,” and it aims to reduce eye strain when viewing your iPhone or iPad in the dark.

iOS 9_3 Night Shift Feature

It’s also designed to get rid of that bright blue light emitted by your device at night that impacts your sleeping habits. According to Apple’s description:

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. 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.

Enable Night Mode iOS 9.3 on iPad and iPhone

To start using it, go to Settings > Display & Brightness > Night Shift and turn it on. Now you can turn on and manually switch between warmer or cooler color temperature. The warmer side is meant to be used at night as it will reduce the “blueness” of the screen.

You can also tap on Schedule and have it automatically turn on or off based on its default settings, or you can customize your schedule.

F.lux is a free app and does a similar thing with lighting for Windows, Mac, and Linux. It has been around for several years. For more, read our article on how to use F.lux to reduce eye strain and help you sleep at night.

Unfortunately, the only way to get the F.lux app on your iPhone or iPad is to Jailbreak your device and install the app through Cydia.

It’s also worth noting that if you’re an Android user, you can use F.lux if you have a rooted device. If you don’t want to go through the hassle of rooting your Android, check out our article on ways to get the iOS 9.3 Night Shift – like feature on Android.

    I really appreciate this initiative of Apple. But honestly, I don’t like this feature. I think it is better to use a blue like protector like “Ocushield” rather than using this feature. It can help only at the time of night on the other hand a blue light protector can protect me 24*7.

    You don’t need protection from blue light in the daytime, in fact it is probably helping to maintain your proper circadian rhythms

    At first, it takes a bit to get used to the contrast. But after using this for a week, I actually like it.

    I’ve updated to 9.3, but Night Shift is not available on my ipad retina … Unless it’s hiding in some obscure corner where I can’t find it.

      I don’t have the option of night shift after updating my iPad mini to 9.3

    Unfortunately the “Night Mode” will not work with older devices with 32bit prossesors. Which devices are these, exactly? Even if your device can update and run iOS 9.3, it might not be able to use Night Shift. These devices include the iPhone 5, iPhone 5c, iPhone 4s, iPad 4, iPad 3, iPad 2, the original iPad mini, and the 5th-generation iPod Touch.

    NightShift will do little if anything to reduce digital eye strain associated with device usage. It may however reduce emission of blue light wavelengths associated with disruption of melatonin production and sleep.

    I think it may help me because I always used my iPad before I sleep. Sometimes I got Eye Strains because of it.
