adjust monitor brightness to the time of day f.lux is a unique tool that automatically makes the color of your computer screen adapt to the time of day. The program calculates the adjustments based on your geographical location and the type of lighting you use at night. As the day progresses, f.lux will gradually adjust the screen brightness and color temperature to match your surroundings, resulting in a more comfortable work environment and less eye strain. If you find that the default night time values are too warm (yellowish) you can adjust them from the settings dialog. The program can be temporarily disabled from the system tray icon whenever you need to have colors displayed accurately (e.g for photo or design work). Copyright Snapfiles.com

Works, but slow transitions 3 stars by dawnskies Aug 08, 2017 (Read all my 9 reviews)
Windows 10 has this built-in now, so I'd rather not use this anymore as transitions are slow and the UI is laggy. Prefer SunsetScreen to this. show Review details
Amazing tool 5 stars by busybusy Aug 16, 2012 (Read all my 176 reviews)
Computer users need a little help now and then with natural illumination when it comes to being in front of a computer monitor all day. This really help with my eyes in the evening hours. They have not updated this link in a while so visit the author's site for updates to this amazing program. Love it, use it, rate it! show Review details
Don't stay up past your bedtime 5 stars by brutallyblue Aug 01, 2012 (Read all my 8 reviews)
I read about f.lux in an article that offered several different ways to overcome insomnia, and also those (me) who tend to stay up too late. It's less than favorable to be a night owl when you have to be at work early in the morning. Even so, every night I'd be at my computer doing any number of tasks and wondering why I wasn't getting sleepy - even with sleep medication. After I installed f.lux, 9 times out of 10, I will go to bed when I am supposed to - and without the use of medication. It seems that what was keeping me wide awake was the bright light from the monitor, and naturally, what sort of activity I was doing. f.lux, follows the natural patterns of the sun, and as the evening wears on, it slowly dims your monitor - so slowly that it is impossible to perceive, and problem is solved. Your monitor has mellowed out by bedtime, and not wildly stimulating the brain into the late, late hours of the night like before. Of course, your mileage may vary, but everyone I've recommended it to has had positive results. This falls into the category of "the first programs I install" after reformatting my hard drive or setting up a new PC. It's an insomniac's best friend, and a must have. Many thanks to Michael Herf, the creator! show Review details
