I have 2 issues with flux, one personal one science related. personal) I'm colorblind and it really messed with my ability to guess at the appropriate colors, and sometimes made it impossible to read text on the screen. (Red on black is hard for me) science) One of their more prominent articles showcases a study of how reading on a stock iPad can mess up your sleep a lot, but reading a book with standard bulb (much w…

That reporting starts from the research links on the F.lux site which 1) don't really say what they they seem to think they say and 2) often conveniently hide behind paywalls. The F.lux team genuinely seems to care about human health yet they haven't bothered to write the equivalent of a three page term paper about what they're basing their work on the past 8 years. It's odd. Even in this thread (as in the other six…

Some people, perhaps against their better judgement, like to use screens even as they're getting closer and closer to sleep. Some even use screens in bed. The difference in harshness of a 5800K screen and a 2700K screen is quite easy to feel in an otherwise dark room, late in ones "day", and once you're used to the latter, it is very uncomfortable to look directly at the former. One of them feels better on your eyes than the other. It's that simple! How exactly does this not make sense?

Enjoy your eye strain...? :-/ I find your laughing at our mutual experience and desire to share it with others, so that they may too use screens with less discomfort, odd. And unlike an infomercial, we're not trying to sell anything.

Now it would be great if android included it in the system soon. I used an app for it, but as soon as 6 came out, I dropped all unnecessary privileges from installed apps. Unfortunately you can't have any app drawing directly on the screen if you want to change privileges. That means I had to choose between silly-bright screen or more secure system... and that's a terrible tradeoff to present to users.

CyanogenMod has it built-in, called LiveDisplay (and even a default tile in quick settings for toggling it).

I use it, and I like it, and I think it works. But I also think they should really try to publish a paper on it, proving it works to improve e.g. people's sleep quality.

What's the incentive to do so? People like the app.

Because liking the app does not necessarily mean it has the effect on sleep as claimed. I would be very interested in studies testing its efficacy.

Android has adaptive brightness, which goes some way towards the goal.

Give it time. You'll get used to it after a while, to the point where a couple of weeks later you won't perceive the colors as "wrong" (assuming no other light source in the room). You'll just perceive them as slightly warmer.

Doesn't this get in the way if you're doing graphical work where you need to know the colours are right?

That's not what it's for, though. For graphics you need D6500, there's no way around it, circadian rhythm be damned. This is mostly for reading things late at night.

I use redshift[0] on my linux machines which I really like. Cyanogenmod has LiveDisplay natively which is practically the same thing unfortunately it works off off gps location and not manually editable lang/long. Both are really helpful. [0] http://jonls.dk/redshift/

Going to jump on this train here. F.lux on every platform I've tried has performance issues.

Guess I better jump on too: I've run flux on three machines with OSX's from Snow Leopard to ElCap: A white plastic Macbook from 2006, a late-2014 Air, and an early-2014 MBP with a triple-head display setup, and never had any problems at all. So YMMV.

There's 29 comments here and every single one is neutral or positive about Flux as an idea. Am I the only one who used it, and hated the fact that my colours were obviously all wrong? Each time I used my computer at night, I noticed that everything was tinted red, and it had no obvious effect on my sleep.

A few things:

* You can adjust the color temp it goes down to. I'd try a more moderate setting, at least at first.

* You can have it transition gradually.

* If the room you're in is lit with daylight bulbs, you won't really benefit from it and it will look weird.

* It's no good for doing color-sensitive work, so no photo editing, etc.

I really can't imagine using a computer in the evening without it.

CM has its own issues though. For example nexus 5 gets monthly security patches from upstream right now, but CM-13 for the same model was last updated in September 2015 :/

That's not comparable. I'm using the lowest brightness 99% of the time already. (the other time is when I'm outside, at midday, in summer) Flux was still a huge improvement in the evening.

There is a large button in the UI that says "Disable for one hour (for doing color-sensitive work)" specifically for this reason.
