Interesting, I'd like to see more feedback first. One issue may be for graphic designers.

Yeah I guess if you are working with colors it isn't the best tool for you. But you could turn it off while working.
Flux it is based on the research that blue light (like sunlight) is sending signals to our body that it is daytime and we have to be active and alert. If we now extend the exposure to blue light until long after sunset (by LCDs), our body doesn't know that it's time to sleep already. By reducing the blue light, at least in theory, we should feel tired earlier, fall asleep faster and improve the quality of our sleep.

More about artificial light and sleep in this post (where I also read about Flux):

Adjusting your brightness doesn't remove the blue light (it probably only lessens it) and therefore doesn't help much (if you believe in blue light beeing the bad guy).
Also I am often to lazy/forget to adjust my brightness/contrast every morning/evening. ;-)

Just installed it. It's night now, and indeed it gives a softer look to the eyes, while the colour change is not that annoying imo. But let's see how it works out long term. Anyway, thanks for the suggestion!

No comments for the sleep-related aspects (while awake--for sleep, I just put my monitor into hibernate ;p), but for the color stuff, I was just recently tinkering around with the warm/cool/etc. settings for my monitor, and reading about creating color profiles, adjusting color temperature, kelvins or whatnot. Interesting stuff. Personally I just leave it 'standard' and adjust brightness/contrast.

Personally for me, bright monitors really kill my eyes. This is why I can't stand using LCD screens,because they are piece of shit eye piercing machines. I use my crt monitor keeping brightness and contrast pretty low.

Thanks a lot for all the links by the way guys, I'm going to give the program a run.

As for the teenager problem - why not just sleep with an open curtain?

Edit: For the guys using the program keep a blog or something on it just so we can track how it is. I know I'll be keepin one^^

Wow, this is exciting!

A lifetime of surfing in the tropics has left me with very early stage macular degeneration, and blue light is waaay bad for the condition. This is the first thing I've heard of that isn't a clunky filter thing. Relief from monitor glare headaches would be a nice bonus, too. And I definitely have a hard time falling asleep if I've use the computer after dinner. I've seen a direct correlation--more use, worse problem. Didn't realize it was the blue light, but makes perfect sense.

I'm installing this puppy this afternoon.

Thank you Proxx!!

I'll try it too, thanks. I often find it difficult to fall asleep whenever I work until the wee hours. And of course those are the nights we most need sleep in order to function well the next day. I hadn't heard of bad blue light. If it helps, Proxx is my new hero.

A somewhat related question: I bought a new laptop last week and the screen has far more reflection/glare than past ones (most recently a tablet.) Is this typical of new LED screens, or...?  If it varies between brands/models, then I'm tempted to return this one.

I haven't checked F.lux yet, but as I can't stand my computer screen's brightness (especially at night), I use a little program called ssOverlay (Windows only).

You can download ssOverlay or Dark Screen here.

The main difference between them is that with Dark Screen you can only select the brightness, while with ssOverlay you can set the "background" color too.  I personally use ssOverlay with "black" as my chosen color and adjust the saturation to whatever feels right according to the ambient light.

Dark Screen (1.03 Mb)

Some computer users experience problems with glare from the screen. Dark Screen sits over all windows and provides a means of dimming the output between 20 and 90%. Dark Screen is multi monitor aware, and can be used on the main monitor only or all monitors. Everything is controlled from the icon in the Notification area of the Taskbar (where the clock sits). Clicking this icon will open the menu which allows the selection of Multi Monitor Support, and the percentage of dimming of the screen



ssOverlay (896Kb)

Very similar to Dark Screen, ssOverlay (the ss stands for Scotopic Sensitivity), places a coloured overlay onto the screen. The colour and transparency levels can be adjusted to suit the user.

I have my iMac screen brightness set all the way to the left, and I'd go minus if I could. Eagerly awaiting nightfall.

Yeah, it's backlit LED. I suppose the apparent brightness (even adjusted) and the reflection/glossiness are two different things. Whatever it is, it feels like my eyes are frying too.

Unfortunately, I'm not able to install F.lux. My computer doesn't doesn't like the install location (...[user]\localsettings\apps\...) , but it won't let me pick a different location. It's meant to work with Win7, though. Any suggestions?

i'm loving it!

My led backlit macbookpro is set at 100%. When I first got it I noticed how much brighter it was than my old fluorescent one and used it at 50%, but I guess I adapted. I also put an anti-glare/protective film on it which reduces the brightness a fair amount though.

Then again I don't use my computer with the lights off unless I'm watching a movie

I might try this. Only issue is that I don't want to leave my laptop screen on all night. My sleep schedule is f'd in the a. Bed at 3, up by 9:45 on Monday, Wednesday, and Friday, and then up between 3 and 4 every other day...
