It’s a little like the sunrise alarm clocks which start your day by gently lighting the room, or the sleep alarms which gradually fade out the radio instead of a sudden silence in place of music.
This free application, called f.lux, changes the colour temperature of your Windows PC’s display, based on what the time is. Once the sun goes down, it starts to change the bright white of your Windows backgrounds to a nice soft glow, with the intent that your eyes will adjust to the softer lighting system when you’re looking at the screen in the evening.
Ditto, early in the day, the less harsh, less bright white screen will be more soothing on the peepers first thing, and that will be altogether better. It’s possible to over-ride temporarily, if you’re doing work that is colour-sensitive (like photo editing etc), and you can preview the effect so when you install the software, you’ll be able to see what it looks like throughout the course of night and day.
Thousands of comments on the f.lux website list people saying they’re sleeping better since their evening PC use with f.lux helps their eyes relax before settling down for the night. If work/life balance is a problem for you, then maybe you should stop using your work PC in the evening... but if you do need/want to use a computer after the sun goes down, give this tool a try and see how you get on with it.
Check out the site to install F.lux - http://stereopsis.com/flux/ - It’s really rather good.
Now, go to bed!
