Night Shift For Mac


Mac OS X has also introduced the Night Shift feature which is nothing but the blue light filter. The function of the night shift is basically to turn on the blue light filter on the operating system and help improve sleep of users who use PC till late night. Almost all major operating system platforms have included the blue light filter in their ecosystems.

I'm using Mac OS Sierra on an 11 inch Macbook Air, using an external Acer 24 inch monitor. I would like Night Shift to be always on. In system preferences - displays - Acer G236HL - the Night Shift tab, here's a picture of the settings: The closest way to getting what I want is to check 'Turn on until tomorrow', which works as expected.

What is this blue light filter? Computer or mobile screens have a bluish hue in their back light. After several years of exhaustive research, scientists from different parts of the world have found out that blue light disturbs sleep by hyper activating the eyes and the nervous system. This is one reason why why can not sleep even if we are tired. The blue light has been found to stimulate nerves and the brain simultaneously and deprives sleep. Since, health is the biggest priority of human life, every gadget manufacturing company have started using blue light filter software in their devices.
When the blue light filter is turned on, a reddish hue filter is applied on the back light and the overall color warmth is increased to some extent. Blue light filters have been found to improve sleep to a good extent. You can turn on Night Shift mode on Mac OS X whenever you require. You can also schedule the time stamps when the night shift mode will turn on or off.

  • Enable Night Shift from Notification Center. Apple introduced many new features on macOS Mojave.
  • Use Night Shift on Mac. Use Night Shift to adjust the colors on your display to the warmer end of the color spectrum. Warm screen colors are easier on your eyes when you use your Mac at night or in low-light conditions. And exposure to bright blue light in the evening can make it harder to fall asleep.

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 computer's clock and geolocation to determine when it's sunset in your location. It then automatically shifts the colors in your display to the warmer end of the spectrum. In the morning it returns the display to its regular settings.
