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.

To clarify, I was speaking to broader claims of people saying f.lux puts them to sleep like a baby and the f.lux authors themselves claiming it as a tool in the fight against cancer and acne. Note that f.lux does not even claim to prevent eyestrain. The closest they come is this: "Our users say that f.lux prevents eyestrain." That's hardly science; in fact it's exactly how shady companies market vitamins. Also, I don't know what "feels better on your eyes" means but I will point out that if 2700K screens felt better "in an otherwise dark room" then movie theaters would use them. You say "It's that simple!" but like most things, it's a little more complicated than that.

  You see no difference between sitting 0.5 meters away from a screen that's projecting its own light or sitting 15 meters away from a screen that has light projected onto it?

    A photon is a photon, regardless of whether it's emitted directly or reflected. All that matters is vibration frequency and intensity of the stream of photons. Do you disagree?

      Maybe kungtotte is talking about accommodation or vergence, though I don't see how these are relevant to f.lux or colour temperature.
