If you're like me and spend way too much time in front of a screen, highly recommend this program:
https://justgetflux.com/Basically, it figures out where you are, and starts dimming your monitor based on the local sun pattern, especially the blue lights, to help you get to bed at a more reasonable time, signaling your brain to start winding down sooner than it would if the full brightness blue lights were on.....
Just something to share, if it's for you, cool.... If it's not, that's cool too.....
