#F.lux for mac os lion software

I’ve definitely found my big, bright iMac screen to be more comfortable to look at late at night when using F.lux-the display simply “matches” the ambient lighting better. (You can opt for this change to happen quickly, but I find the hour-long transition to be much less jarring.) Similarly, if your computer is in use at sunrise, F.lux gradually brightens the screen and shifts its color temperature back to normal. Once the sun starts to go down, the utility gradually-over the course of an hour-dims your screen and shifts its color temperature to match that of the type of lighting in the room. (This is the layman’s description, of course.) Thus, it should come as no surprise that looking at a computer display late at night-particularly when that display is calibrated to be bright and clear during the daytime-can be both visually irritating and a contributor to sleep problems.Īfter that simple setup, F.lux sits in the background, waiting for sunset. According toĪ good amount of research, part of the problem is that bright light-and especially bright light of particular color temperatures-keeps your brain from progressing through its normal “it’s getting later in the day, lets start winding down” process.

If, like me, you tend to occasionally work (or play) in front of your computer late at night, you may find it difficult to sleep soon after. As it turns out, there’s more to display-viewing fatigue than brightness.

Your screen’s brightness beyond the normal hardware and software controls, but most of these utilities focus on simply reducing brightness. Some of today’s LCD displays are so bright they can be uncomfortable to look at-especially at night.
