Are You A Night Shifter?

What is Night Shift Mode?

Night Shift Mode was a released in IOS 9.3 and has escaped many including myself as a feature of some significance. Night Shift mode allows the user to adjust the screens brightness and colour temperature to cut down the amount of blue light emitted by your device.  

Blue Light

Blue light has direct links to some major health risks as mentioned below in the diagram. As educators it is important to make students and parents aware of these associated risks of exposure to blue light. Especially now that most schools are rolling out 1:1 devices the need to be educated about the effect of long periods of exposure to blue light should be a compliance all stakeholders are aware of and part of any school's 1:1 OH&S policy. 

On the Kelvin scale used to determine color temperature, an iPhone 6 display measures at about 7100K, while an iPad Air 2 display is slightly warmer at 6900K. On the lighting spectrum, 6900K and 7100K blue light levels are similar to the light you would see on a bright, cloudy day outdoors. Blue light is also harder on the eyes, especially in an indoor room that's lit with a dimmer yellow light.

Night Shift Devices

Night Shift is a feature in iOS 9.3, but as it turns out, it isn't a feature that's available on all of the devices able to run iOS 9. Night Shift requires a 64-bit processor, which encompasses the A7, A8, A8X, A9, and A9X. The iPhone 5s and later, the iPad mini 2 and later, the iPad Air and later, the sixth-generation iPod touch, and the iPad Pro can be used with Night Shift.

Night Shift can be scheduled to automatically turn on and off at what ever time you like including screen brightness.
