How to Eliminate Blue Light with Windows 10 Night Light

  • MORE

Studies show the blue light cast by bright screens (such as the one on your laptop or mobile device) reduce our ability to fall asleep fast, and maintain our energy throughout the day. This light actually tricks our brain into believing it’s day time, which throws off our circadian rhythm, but that’s a scientific query best left for googling.


At first, we had f.lux, an app that aimed to remove the blue from our screens that kept us up at night. In newer Windows 10 builds, the functionality is baked right into a feature called Night Light. Here’s how to activate it.

1. Open the Start Menu.

start2. Click the gear icon to bring up the Settings Menu.

display5. Toggle the Night light switch to On.

on6. Click Night light settings to adjust the level of blue displayed, or determine the time for Night Light to activate automatically.

    I use sites like Swagbucks, and my favorite offer resets at 11pm Central. Now that I have the Night Light, my late night laptop usage interferes less with my ability to fall asleep. I have noticed fewer late night headaches as well.

    I have had insomnia and migraines since my earliest memories from childhood. I'm not saying the Night Light is some miracle cure, but it doesn't​ exasperate my existing symptoms.

    It would help if you could be a bit more specific about newer windows 10 my system has the anniversary update, but does not have this feature.
