If your typical workday is anything like mine, much of it involves staring at a computer screen. But even when you go home at night, you have emails to return, Facebook to check and you may even watch movies on your computer screen. That’s a lot time spent staring at your monitor! And it’s not just the time spent that can start to hurt your eyes. When the sun goes down and the lights go on, the contrast of the bright screen at night can be blinding.It isn’t just eye strain. Looking at white light tricks your body into thinking it’s daytime. That means it’s harder to go to sleep.
What if your computer monitor behaved more like natural light? What if it got brighter in the daytime and softer at night? And what if the color temperature could warm or cool to reduce eye strain and keep your sleep cycle intact?
F.lux is a free downloadable program that can automatically adjust your monitor’s brightness and color temperature according to day and night cycles in your area!
F.lux automatically calibrates the computer or device display's colour temperature
to the time of the day. The user also has the option of choosing a
color preset or disabling f.lux for an hour and returning the screen to
its normal calibration. The software offers three preset color settings
on Microsoft Windows: halogen, fluorescent, and daylight—as well as Incandescent on beta. For OS X, candle and tungsten settings are also availableIt’s simple: Download and run the program. If you’re connected to the Web, it can automatically detect your location and will begin adjusting your display immediately
You can click Settings to change your location if it’s incorrect and you can alter the brightness and color settings according to the lights you use in your office or room.
If you need precise color representation while you edit photos or do other color-sensitive tasks, you can disable f.lux for an hour with just one click.
Or, if you want to watch a movie and have the colors look right, you can put F.lux in Movie Mode. This disables f.lux for two and half hours.
A quick warning:
If you first install and run F.lux at night, your monitor will suddenly take on a serious shade of red. Don’t worry; that’s normal and you’ll get used to it fairly quickly.
If the colors still don’t seem right to you after you’ve given yourself an hour or so to adjust, you can change the warmth setting until it looks like a book page under normal lighting. This is the most natural setting for your eyes.
