For anyone else forced to sit in front of a computer most of the day, F.lux is a free, great addition to install immediately.
What is F.lux? It’s a tiny program that automatically “makes the color of your computer’s display adapt to the time of day, warm at night and like sunlight during the day…f.lux makes your computer screen look like the room you’re in, all the time…Tell f.lux what kind of lighting you have, and where you live. Then forget about it. F.lux will do the rest, automatically.”
I’ve been using it for a week now. I can’t prove it, but I would say it’s helped me sleep easier, and the screen looks better. It does take a little initial getting used to, but it’s awesome seeing the screen adjust during sunset towards a warmer, orange glow.
