Ever notice how people texting at night have that eerie blue glow?

Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen?

During the day, computer screens look good—they're designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn't be looking at the sun.

F.lux fixes this: it makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.

It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better.

在国内有很多软体基地都提供该软体的下载，但该软体为英文版本(目前还未出现中文版本），您只需要在百度搜寻这个软体的名字即可（提示:在搜寻该软体的时候一定要记住是 F.lux 而不是Flux 记住F后面有一小点）

Ubuntu10.04+用户可通过命令安装:

sudo add-apt-repository ppa:kilian/f.lux

sudo apt-get update

sudo apt-get install fluxgui

Linux其他发行版用户可到主页下载。

f.lux 会据此判断日出、日落时间，分析出特定时间的光照强度，并以此为依据调节萤幕。

F.lux我们大致可以理解为是根据日落时间来判定萤幕明暗度的调整时间，所以这里的设定的时间就是非常之重要。

套用截图

由于软体是国外的，那边的时差和我们中国有一定的差距，设定中可以为我们提供不同国家和不间的明暗调节。

这里我们只需要设定 地理位置的经纬度即可。

例如我们输入29.35 ，106.33 就可以直接转为中国重庆的经纬度。
