This is useful when you do photo or image editing, as you won't be able to do some of the editing if the color temperature is modified (as colors appear different than they really are). You may configure whitelists for programs, so that F.Lux shuts off its functionality whenever these programs are active.
#F.LUX FOR MAC OS WINDOWS#
You need to select Menu > Change Color To > Expand Color Range for that. The lowest that F.Lux supports on Windows is 1200K. F.Lux, on Windows at the very least, comes with options to expand the color range. Some operating system block the lower color temperatures by default. This can be useful as F.Lux may adjust the color temperature automatically based on that. The preview takes only a second or so before the current default value is activated again.Īnother option that you have is to set your wake time. The color warmth of the monitor is changed automatically each time you change a value so that you know exactly how it will look like in the future. Simply move the sliders then for daytime, sunset and bedtime to adjust them accordingly.Īpart from setting Kelvin values directly, you may also set them to one of the defaults, e.g. You may also select custom values instead if you prefer that. If you do, adjustments are made right away and the daytime, sunset and bedtime values may change. F.Lux ships with color presets of which you may choose one. You have two main options when it comes to that. Adjustments to the default settings can be made in the program's options. You can run a 10 second 24-hour preview to see how the display changes in that period. The program displays a curve when you open its interface that highlights the time of day, and the warmth of the screen. Note that you need to enter the nearest city or location on first start, as default values are selected by F.Lux automatically based on the information. Computer light however is so bright, that there is no indication that the end of day is near (read sleep).į.Lux ships with default values that you may use right away, or adjust to your needs.

In layman terms: A reduction of blue light is interpreted by the eye/brain as an "end of day" situation. One of the gains is that the display won't be as eye hurting anymore in low light situations, another that you may fall to sleep easier thanks to the reduction of so-called blue light by the application.
#F.LUX FOR MAC OS SOFTWARE#
Speaking in technical terms this means that the software will reduce the Kelvin degrees of the light to make the light feel more natural and pleasing to the eye.į.lux fixes this: it makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day. The software adjusts the color temperature of the computer monitor automatically based on that.
#F.LUX FOR MAC OS MAC OS#
F.Lux reviewį.lux is a small computer software program for Microsoft Windows, Mac OS X, Linux and Android that adjusts the brightness of the computer monitor according to the time to day. It may feel like starring right into the sun at times, and for a long time, there was little that you could do about it other than either turning the brightness way down, or making sure your eyes adjusted to light before turning on the computer. You may have also noticed that it takes some time to get used to the display when you turn on the computer for the first time in the morning, or even during the day.

It is not a very pleasant experience, and it may take minutes before your eyes adjust to the brightness of the screen. If you ever had to get up late at night to work on a computer system, you may have felt blinded by the bright light of the computer screen at first.
