If you are spending more than 3-4 hours while using computer then light of your computer screen may hurt your eyes.So it is very necessary to protect your eyes from screen light.F.lux is a software which can protect your eyes when using a computer. F.lux makes the color of your computer’s display adapt to the time of day, warm at night and like sunlight during the day.During the day, computer screens look good because they’re designed to look like the sun. But, at 8PM, 9PM, or 4AM, you probably shouldn’t be looking at the sun.

F.lux does a simple task to adjust the colors and brightness of your computer screen according to time.In day its uses colors combinations which are suitable for day light and at night its uses different color combinations.When I started to use F.lux for first time it looks odd to me for few days but after continuously using it for a week I found that this software really works.I am using this software from more than 2 years and now I will recommend to everyone to use this free software .

The size of F.lux is around 500KB and it doesn’t require a lot of memory to run so it will not effect the performance of your  computer.
