I’m a hardcore evangelist for a program called f.lux. It adjusts the color temperature of your monitor according to the time of the day. Once the sun sets, the screen starts turning to a warmer color and eventually the bright blue glow turns orange, or deep red (depending on the settings).
Why would you want to mess with your screen settings? Staring a bright screen emitting bright blue light late into the evening messes with your melatonin (a hormone critical to good sleep) secretion and makes it harder to fall asleep / affects the quality of sleep. I just made all of that up but here’s a bunch of science on the subject: https://justgetflux.com/research.html
If you aren’t convinced, install the program and run it for 10 minutes in the evening. Then turn it off. It’s like your retinas are on fire. Just try it.
