Also,
F.lux is a really neat app that can help you get to sleep easier after a session of using your computer. The blue light produced by computer screens is known to inhibit sleeping ability, so this app will actually fade away the blue light displayed by your monitor by filtering your screen a tinted red, which is
much easier on the eyes at night which immensely reduces eye strain and can help you get to sleep easier. Best part is, it turns the red filter off during the daytime when it's not needed, and gradually turns it on as the sun sets in your specified location. Super neat.

There are also equivalent apps for your phone's, F.lux for iOS and Twilight for Android. I find this to be wonderful for night browsing when you're laying in bed staring at your screen. Really helps with eye strain, and it's helped me sleep easier too.
