Anybody here using flux?
I used to use it, but I deleted it for one reason. I wanted to confirm my findings yesterday so I installed it again.
Today I woke up, sat down for like 1 hour, and my left eye was so red from blood vessels it looked like something hit me in the eye.
So I deleted f.lux and now the redness is almost gone. Am I the only one with such experiences with f.lux?
I tend to stray away from programs like this. From personal experience, any sort of shifting or bright colors will strain the eye. The solution to eye strain from computer use shouldn’t be to change the colors but rather to dim the screen or just cut down on time.
Anyways, I think putting any sort of color filter over the screen makes it harder to view, and thus makes your eyes strain more. I mean, you’re not supposed to look directly at the sun and it’s hard to see things at night.
I’ve been using it for a few months and I really like it. Without it during the late night the screen really burns my eyes, but thanks to f.lux that problem is solved.
I use f.lux, and for me it makes me easier to see the monitor at night. One time, I accidentally disabled f.lux at night and as soon as the yellowish tint has gone I was immediately hit by the white glare my computer had.
If you are having problems with f.lux, maybe you can adjust the settings? I have my set somewhere between Daylight and Halogen because Halogen is two yellowish for me. Although if you are having experiences like getting eye sore , I guess maybe you should stop. F.lux isn’t quite for everybody
Personally I love flux. Every now and then I will turn it off to see how I do without it, but it never lasts long.
As a graphics programmer, I would never ever use any program that messes with the colors of my screen.
f.lux is great, been using it about a year now I guess.
About the red eye, correlation != causation.
I have been using f.lux for about 2 months. It’s great! If I turn it off at night, the screen is terribly harsh on my eyes. It does take some getting used to. I wish it had a transition time longer than 1 hour.
I have an artist friend that uses it. When he cares about color he disables it (alt+end).
It seems that this was just a coincidence, and my eye redness is no flux fault.
It seems that if I eat even few small bytes of smoked bacon (i don’t know how to properly translate it) my eyes turn red if I sit even for short periods of time in front of computer for next 2 days. I remember eating some of it the night I downloaded flux. I’m using it now also and enjoying it 
I don’t even know how can such coincidences happen…
I’m old school. I don’t work in the dark nor in overly lit environments. Indirect lighting is your friend.
When it gets dark I turn on table lamp That way screen is not too bright. I don’t understand people who spend their night with monitor and back lit keyboard’s lights.
My guess is: pr0n
Yup, I use a 300W halogen torchiere lamp (aka an uplighter) positioned just behind me and usually set at ~85%. I’m still amazed when after using f.lux for a while I turn it off, the screen is so brutal on my eyes. I really think f.lux is on to something. There are similar apps for cell phones, though I haven’t tried that yet.
It will seem very pink at first because f.lux starts way too low. If you try it, start with maybe 5800K (or whatever doesn’t look horribly pink to you) for a day or two, then slowly move it lower. I did this until I’m down to 3500K and the pink no longer bothers me.
I use it on my jailbroken iPod, and it works wonders at night.
On the computer, not so much. It tended to cause issues with X on my arch system.
There are two different issues here. The first is eye response/fatigue related to lighting conditions luminosity of monitor vs. environment. This issue is solved by working in a properly lit environment and properly set gamma response. If you need to work in more than one then the answer is a different gamma response per environment. Also properly choosing color schemes, fonts and sizes certainly play a role. Check your white-point, black-point and reference images. If you’re not a professional digital artist then an exactly calibrated monitor isn’t very important.
The second issue is the reported correlation between sleeplessness and expose to light in the blue range at night. Seems plausible since we get hit with more blues during photopic vision (day) than otherwise. My color selections are mostly “cold” and never have sleeping problems so I’m not concerned. If you think you effected then it would make sense to try changing to “warm” color schemes.
I just repeeked at the web-site. Ignoring comments like: “they’re designed to look like the sun” (WTF?) The colors of the site: text vs background colors are very not eye-friendly.
I’ve been using f.lux for several months now without noticing any problems, it turns on when the sun goes down - making me actually notice the sun going down nowadays. On my Mac, I’ve noticed that closing a LWJGL window disabled flux for a short time. I’m not sure if this is the case on Windows; I don’t use my desktop computer at night.
Besides, Windows font rendering in Eclipse is terrible.
