f.lux your PC

I know most of us like to work in front of your computer at least 12 hours a day, and keeping your eyes focus on the LED screen is tiring. One of factors is your screen's brightness. Sometimes we just don't have idea on how to adjust the degree of brightness, since It's difficult to decide which level of light exposure is safer for us. 

Here's a solution for those of you who are like me, have unfortunately have your head nailed to the PC screen. It's an amazing software called F.lux. No kidding! this little software really save my day! Rather than calling it a software, I prefer to call it an app, a small size which only cost you 546.3 KB of disc space. The installation is speedy, which takes only few seconds to complete. 
 
After the setup has completed, you have to do some setting according to your preferences. The setting seems convincing, which provide you logical options like adjusting your preferable lighting for day and night, setting your current location based on coordinate, and also the transition speed of the screen brightness. It also allows you to disable the app for an hour if you are working on something that requires precise colours. 


After the setting is done, you can now seat back and let the app do its job. During day time, it will change the screen colour to a colour that matches the sunlight, allowing you to work comfortably under normal sunlight condition, without straining your eyes. It even tells you approximately the time left before sunset. At night, it will change the colour of your screen to make it more soothing when you work under a fluorescent or halogen lamp (can be adjusted during the setting). 


In short, this app is very practical and ridiculously fun. When you have learnt this app well, you can manipulate this app easily and make use of it in the way you desire.
