I just want to remind everyone that LED backlights emit blue light that isn't eliminated by f.lux or similar utilities.
You might want to refer to our measurement project for some numbers: https://fluxometer.com/rainbow/ Also, you can be below threshold for circadian responses just by being very dim.
f.lux author here, still slogging through the article. It is hard to understand the light levels used because they use "power" (uW, mW) from a laser, and not "irradiance" (uW/cm^2 or mW/cm^2), so which area they have concentrated that light over is hard to understand. All I can see is it is from a laser, so the irradiance could be extremely high. The human lens filters most light at the peak of the given spectrum for…
Hi herf, your software is really nice but one thing that kept me from using it (and adopted since Apple's 'night shift', though I don't use all days) is that I enjoy photography. Probably you heard this a few times, but one thing that I'd love to have is this off for photos (I'd switch from being an eventual user to being a full-time user).
I was very happy when I found f.lux. Finally something replacing my own tool I wrote for my Atari.
The main benefits with f.lux is you can easily set brightness and on/off with keys in any program or game, no need to navigate with mouse in menus.

Have we fixed the “optimized for electronics store demo” problem with monitors yet? Part of my ritual of setting up a new monitor is to turn down the brightness and increase the contrast. They almost always default to very bad values. Brightness, temperature and green/blur balance are all off for an office setting. In the worst case the backlight was capable of outputting twice as much light as I really needed.
When I got my first LCD monitor, the first thing I did was turn the brightness down to 0 and the contrast to slightly above; at that point it was already plenty bright enough, and after a few years when I noticed the brightness begin to fade I increased it 2-3 notches. I suspect part of it is also planned obolescence --- when the backlight is running at full brightness, its lifespan is greatly decreased. Now the afor…

This isn't weird at all. I'm jealous of your 1%. The default low on my phone is maybe like 5-10% (I don't know how to check this), and it feels crazy bright when I'm in bed.
If you're on Android, I recommend Screen Filter[1] which will draw a semi transparent overlay on top of nearly everything (depending on the phone and/or OS version, it might not dim the status bar, bottom navigation buttons, lock screen, etc.). I use it a lot when reading at night, because the lowest brightness setting on my phone is also too bright for dark-adapted eyes. [1] https://play.google.com/store/apps/detail…

I used f.lux for 2 years. I found that I would stay up way past my bedtime, glued to the computer screen, and end up with correspondingly tired & fucked up eyes.
So I got rid of f.lux, and after that, I would go to bed at a more proper time. When the screen starts irritating my eyes, it's a direct indication that it's time to close the computer and get the hell to sleep. Ever since that, my eyes have done a lot better, because I no longer push to stay up way past my bed time.
Really surprised there's no discussion here about the ubiquitousness of black-on-bright-white color schemes in apps (including this text box I'm typing into right now, though for the most part, HN uses a soft beige tint for its background; but it's still dark-on-light). It's really quite unnecessary. For code editing I have a light-on-dark Emacs color scheme, which is much easier on the eyes. Yes, Macs have a setting…
For many of us with astigmatism, the trend to default to dark schemes would be quite troubling. They're painfully uncomfortable irrelevant of contrast. There's fuzzing and "halation". It took me a long time to figure out the why. I love dark layouts in terms of aesthetics, but I cannot use them. Without being biased, from what I have read so far, the research seems favorable for dark-on-light as long as proper room l…
I don't quite understand. Blue light - any blue light - causes blindness? So we shouldn't look at the sky even? I've never heard blue being a danger other than its effect on the biological clock, so that seems like a pretty bold claim. Ultraviolet, sure... Though buried in there is something about immune system and vitamin E levels... I really find it hard to believe that blue light exposure is automatically bad. We…
When you look at the sky during a bright day your pupils are narrow and let little portion of the light through. When you look at blue light in the dark - they are dilated and let more light through.
I use f.lux all day I don't know if I'm particularly sensitive or if it's all in my head but when I turn off f.lux, especially at night, to watch some movie or video I can physically feel my pupils dilate and it almost feels like my eyes go from being at rest to being strained.
As a linux user, I have found that Redshift works better than f.lux. It's the first thing that I install on a new machine of mine.

What makes f.lux inaccurate? Color perception is relative and if you are in a dark room, your eyes should adjust to different white points naturally. This is the same thing that makes it so a white piece of paper looks white no matter whether you are inside or outside, even though the actual light reflected from the paper has a radically different spectrum in each case.
I'm not OP but I can't stand f.lux and its clones. I never adjust. The inaccurate colors stand out to me no matter what the conditions are.
Colors appear to change dramatically under different lighting conditions, but we accept these changes as normal given context. Changing the white balance on your screen is no different. It's not inaccurate, it's just rendered as if in different lighting conditions.
