How Night Shift works

One of the new features that will come in iOS 9.3 is the so-called Night Shift, which promises to improve the night of those who usually touch the iPad or iPhone before going to sleep. Understand how it works.

What is?

Night Shift is a change in the colors of the screen between a certain time, so you don’t get so tired when reading at night. The screen is reduced in blue light and has warmer tones (yellowish), because according to some studies, this tires your eyes less and does not influence your sleep when you go to sleep.

Some Mac, Windows and Linux users are already familiar with the function, which is well known to anyone using a program called f.lux (which also has a tweak jailbreak).

How it works

It is the user who determines whether he wants to activate the function and when it will be active, in the menu Screen and Brightness Adjustments. You can choose whether you want it to automatically activate from sunset to sunrise (and this will be adjusted with the help of the clock and the identification of the geographic location you are in) or else in a personalized time band. The operating mode is very similar to the already known Do not disturb, and you can immediately activate the function whenever you want.
