Windows 10 Night Light

This applies to Windows 10 Creators Update (version 1703)

Many of you are familiar with the freeware program f.lux. It’s a program that changes your PC screen at night so it displays whatever you’re viewing in warmer colors. Some brainy scientists somewhere decided that harsh blue light from PC screens can keep you from falling asleep at night, but warmer colors (oranges, yellows and reds) can help you fall sleep. I am not sure about this, but I’m not a brainy scientist.

Anyway, Windows 10 Creators Update (version 1703) has a feature like f.lux (although f.lux is much more robust) and all you have to do is turn it on.

Let’s turn it on now, OK?

Go to Settings > System > Display

In Display, beneath the brightness slider, you’ll see “Night light”.

First, you will need to turn the on/off switch to “On”.

Then click on “Night light settings”:

As you can see in the screenshot above, you can adjust the “warmness” of your screen colors for night time viewing.

Next you’ll want to schedule the hours the screen will display warmer colors. I don’t have my location turned on in Windows 10, but if you do (or if you want Windows to know your location, you can click Location settings) Windows will automatically warm your screen colors at sunset in your location and turn off Night light at sunrise in your location. If you don’t want to let Windows to use your location, you can manually set the hours you want your screen to display warmer colors for night time. Just tick the circle next to Set hours, and set the hours you want Night light to turn on and off, see?

I have my “Night light” set to turn on at 9:00 PM and turn off at 7:00 AM.

I am not sure how well looking at warmer screen colors at night helps me sleep, at my age I can barely stay awake past 10 PM 🙂

But, at least now you know about the “Night light” feature in Windows 10 Creators Update (version 1703). I’m pretty sure you’ll want to play around with.

And, if you fall asleep faster, after turning Night light on, let us know!
