Prolonged use of computers can sometimes lead to irritation in the eyes, particularly when the display is bright and the usage continues till late at night. Symptoms may include difficulty in reading, headache and sleeplessness.
The reason behind this is very simple. During the daytime, computer screens look good as they are designed to look like the Sun. But during the evening and night our eyes get tired by looking at the bright (sun-like) computer screen giving which leads to eyestrain.
F.lux is a simple, yet very effective software that handles this problem very well. It adjusts the colour temperature of your computer’s display according to what time of the day it is.
Color temperature is a term that describes how much red or blue, the light is. Natural light is more blue, whereas artificial light is warmer, i.e. more red.
During the evening and at night, F.lux automatically changes the colour temperature of computer screen to warm. This makes the computer screen look like indoor lights i.e. a fluorescent or halogen like warm color. As a result, our eyes don’t stress even if we are using the computer till the late dark hours.
Using the software is very easy. All you need to do is download the setup file from the f.lux website and install it. Then fill in your location and F.lux will do the rest. It will automatically change the colour temperature of your display to warm depending on the local sunset time and revert it back to normal the next morning.
Users of F.lux might take some time to adjust to the new colour settings. If you find your screen too pink or orange you can set the color manually by clicking the ‘Change Settings’ button after clicking on the F.lux icon in the taskbar. For colour intensive work such as using Photoshop it might not be a good idea to keep F.lux running all the time. For this, there is also an option to disable F.lux for an hour after which it starts functioning automatically.
F.lux is available for Windows XP/Vista/7, Mac OS X, Linux and iOS. Android users will need to wait to get the benefits of F.lux. Also if you are an iPhone or iPad user, keep in mind that you will have to jailbreak your device before you can start using F.lux.
All in all, F.lux is an amazing software that does it’s job and its makers have rightly called it as a software that will make your life better. Having used it for a few days now, I can strongly recommend it as a must have for your computer.
Please share with us your experiences using the software and if it helped you work longer hours on the computer without the eyestrain.
