This is something I really couldn’t live without anymore. f.lux is a little utility app available for Mac, Windows, Linux and iOS1 which makes the color of your display adapt to the time of the day. One hour before sunset it slowly begins to make the colors of your display warmer. It does that so smooth, that you don’t even notice it’s happening.
On their website they are talking about how blue light can keep you up late, hence f.lux actually helps you sleep better. I don’t really know about that, but I have definitely noticed my eyes being much less strained since using f.lux. Additionally, turning it off has has become a bit jarring by now. You should really try it out!
if you’re into jailbreaking. ↩
