Stereopsis
f.lux makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.
Ever notice how people texting at night have that eerie blue glow? Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen? During the day, computer screens look good - they're designed to look like the sun. But, at 9 p.m., 10 p.m., or 3 a.m., you probably shouldn't be looking at the sun.
It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes

It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better. Tell f.lux what kind of lighting you have, and where you live. Then forget about it. f.lux will do the rest, automatically.

The last version did not have this problem - at least not for me.

The ability to customize the color used at night time is probably it's strongest feature. This enables me to set it to suit my preference rather than use the default settings. The new version takes a little time to tweak, given the new variables, sunset and bedtime, but it's well worth the effort.

My main problem with f.lux has always been remembering to keep it switched off when watching a movie or using graphics software. This update addresses that problem, allowing you to disable f.lux for the rest of the night rather than one hour, and also for individual apps: just select Disable from the f.lux menu and the current app will be excluded. I'd prefer to have an editable list of exluded apps in the preferences, but this is a workable solution.

Features I hope the developer will add: a setting for white LED bulbs; ability to change the color temperature to red to preserve your night vision; and an integrated dimmer (so I can use one program instead of two).

The only improvement I could hope for would be to add different durations for the dim effect (2 or 3 hours).
For those having blinks if used together with Shades, you can instead use Shadeit! (version 1.1) which doesn't conflict with F.lux. ;-)

Instead, Shadeit! version 1.1 is not a dimmer but a black screensaver.
