f.lux : Automatically Adjusts Your screen Brightness

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.

During the day our screen should look bright and it makes the display look like that but at night it should be bit relaxing to the eyes, this is what this tool does.

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.

f.lux makes your computer screen look like the room you're in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.

Tell f.lux what kind of lighting you have, and where you live. Then forget about it. F.lux will do the rest, automatically. This means you have to feed F.lux with two vital pieces of info if you want it to be efficient: “Indoor lighting” and “Your location”. F.lux automatically proceed to track the sun’s position(day or night) in your zip(pin) code or latitude, and make the appropriate display adjustments.

F.lux will set the screen monitor bright during the day and gradually dim it as evening approaches. At night, the screen will take a “halogen” tinge – an orange kind of hue. The lighting software will automatically adjust the color temperature of the computer monitor.

F.lux is not suitable for design work,there is an option that allows you to disable F.lux for 60 minutes, so you can get your work done in that amount of time, and then reactivate it. This is a freeware and supports WinXP/Vista, Mac os x and Linux operating systems.
