Difficulty adjusting
-
I don't know if this is the result of not being used to a reduced blue light, but flux kind of bothers my eyes, especially when I switch my attention to something other than my computer after viewing it for a long time. It makes everything else look like it has different colors for awhile. Have there been comments in the past from people saying it is difficult for them? It's not as bad when I turn off all the other lights on in the room, but I heard that's not good for you. Also, the main page says "tell f.lux what kind of lighting you have," but I don't recall being given that option. Is there something I'm missing?

@RonanWarrior Well what kind of lights do you have? Are they bright daylight white, typical office 4100K white, soft white around 3000K or warm white with a more yellow cast 2700K?
Also are they the curly CFL lights or LED, and if you don't mind, what brand?
F.lux should make your screen look like a piece of paper or a book on your table. I think the default "bedtime" setting may be what you are seeing. I think it's 1900K or lower. Bump this up to 2300K which is like a dimmed Incandescent bulb.
Set sunset to 3400K which is similar to a really bright 500 watt halogen light.
Let me know if that helps.

Maybe you're missing the Preferences screen? Where you adjust all your colours and timing?
It's generally a good idea to match your screen colour and brightness to your room lighting. You're right that it's not good for you (can cause eye strain) when there's a large difference in the brightness of your screen, compared to the rest of the room.
Most people use ~2700K "warm white" bulbs at home after sunset, so that's a good place to start for the Sunset colour. But you can adjust it to whatever suits you. You should also manually adjust the brightness of your screen to match, since f.lux doesn't do that (and is currently incompatible with auto-brightness).
Where I live, sunset comes much too early in the winter, so I turn on some bright "daylight white" bulbs and leave my screen at full brightness until 7pm or so. I've set my Location to somewhere where it stays light until then. When I notice my screen is changing colour, I turn off the daylight lights and switch to dimmer warm ones, and turn down the brightness of my screen a little.
The Bedtime colour is more important in terms of not keeping you awake at night with too much blue light. I find the default is too orange though, so I set it a bit higher than that, and turn the brightness of my monitor down a lot, which accomplishes the same thing. Then I also turn off all the lights except one small 4W LED bulb which I put some orange-coloured film over. That gives a good balance with the late-night screen setting.

@Elhem-Enohpi Wow, you've really got it down! I'm very impressed. I wonder just how many people do things like this, I wish more people were aware of the effects, but until then, this is still awesome!
