Night Shift automatically shifts the colors of your device’s display to warmer (orange) after sunset for your overall health and wellbeing. Studies show that exposure to blue light after sunset may impact circadian rhythms, making it much harder to fall asleep. To counteract this effect, Apple introduced Night Shift to its iPhone, iPad, and iPod and later its Mac.
Night Shift is available on iPhone 5s or later, iPad Pro, iPad (5th generation and later), iPad Air or later, iPad mini 2 or later, and iPod touch (6th generation and later.) For example, if you have an iPod touch 5 or an iPhone 5C then there won’t be any Night Shift option to select from.
The Night Shift mode feature uses your device’s clock and GPS for the location to determine when is the best time to have Night mode turned on.

Night Shift not working on macOS?
When you turn it on, Night Shift uses your Mac’s clock and geolocation to determine when it’s sunset and automatically shifts the colors in your display to the warmer end of the color spectrum. After sunrise, Night Shift returns your Mac to its usual setting (less warm, more blue.)
If Night Shift isn’t working on your Mac, first check that it’s turned on
- Choose Apple menu > System Preferences > Displays

Worked for me. Thanks.
In my opinion best solution of this problem is not to use this feature. Try any screen protector which can protect harmful blue light. This short wavelength light is known to cause eye strain and fatigue, as well as to increase the likelihood of eye diseases. I can currently using “ocushield” screen protector, which can prevent blue light.
