Adapting your computer screen to your wellbeing

F.lux adapts the color temperature of your computer screen to the time of day, letting you increase your productivity and sleep quality. 

Stay in rhythm

You don't have to suffer the harmful effects of blue light again, thanks to F.lux's screen temperature adaptation system.

Blue light wavelengths contain more energy than other colors, and unlike UV rays, your eyes can't easily block out these wavelengths. The over-exposure to this, which results from staring at a screen for long periods of time, can damage light-sensitive cells within your retina.

Blue light is capable of causing macular degeneration, which is a leading cause of vision loss in the older generation. Blue light also contributes to eye strain as the wavelengths are harder to focus. And if you've ever had cataract surgery, then blocking out blue light is even more important. Cataract surgery can lessen your defenses against blue light.

However, blocking out all blue light is not good for your eyes either. That's why F.lux is a great application to have installed if you spend long hours behind a screen. F.lux manages your screen's color temperature to mimic the room you're in and the time of day.

This means you don't have to strain your eyes when you're typing up an essay or document, even if you're working for 20 hours straight. F.lux will decrease the color temperature you're exposed to as the day goes on, changing the screen at sunset, bedtime and daylight hours.

Where can you run this program?

F.lux is available for Windows computers and starts up automatically whenever you boot up your computer. F.lux is free, and the installation process is smooth. 

Is there a better alternative?

No, while there are other applications including Windows settings itself, F.lux changes the temperature on your screen as the day passes, not just at nighttime like most applications available.

Our take

F.lux is a good application for anyone who spends long hours behind their computer, whether working or gaming. F.lux might just save your vision.

Should you download it?

Yes, this app is a must-have for every computer. Blue light is a factor in the increase of vision loss, and it is easily avoidable.
