Windows 10 Night Light settings

By default, the Nightlight mode will be scheduled to activate between sunset and sunrise. For more advanced control, click Night Light Settings, right under the Nightlight switch. In the Nightlight settings, you will get a short explanation about the fact that “Screens emit blue light, which can keep you up at night. Nightlight displays warmer colors to help you sleep”. Then, you get a switch that does the same thing as the one before: turn the Night light mode On or Off.

Then, you will see a slider called “Color temperature at night.” Dragging this slider to the left or the right will make your screen use warmer, yellowish colors to reduce eye strain, or the regular cooler and blueish colors. Play a bit with this slider and see what’s the color temperature that feels best to you at night. If you do this at night, it shouldn’t be too hard to find the right setting, where you can feel your eyes begin to relax a bit. In the same “Nightlight settings“ window, right after the “Color temperature at night” slider, you see a section called Schedule. If you turned the Nightlight On, the Schedule Night lightswitch will be On and set to be applied between Sunset to sunrise. The exact time of sunset and sunrise is automatically calculated by Windows 10 depending on your location. Also, click the Set hours radio button. The screen will add a section where you can set a schedule that fits your preferences and work patterns.

Activating the Windows 10 Night Light feature could improve your ability to sleep when the work is done.
