Brightness and contrast question
I know you are not doctors or specialists (or maybe you are) but i need to understand something. So i started to use this program today,i like how it perform a lot and i heard good things about it. But i am confuse with something. Let me tell you that i use my pc a lot and i have some problems because of this. I hope this software will help me fix this to avoid them in future.
As i said,i use the pc a lot,i take breaks,i have natural light in room (sometime is dark because weather,you know) and i want to ask you what monitor Brightness and Contrast is perfect to use in general for monitor? I mean,now i use F.lux and i have 80 brightness and 50 contrast because default are 100 brightness and 80 contrast on standard mode (i don't have Color control in monitor) but it's kinda dark for me with this settings.
I think this monitor (Asus Vp228HE) is kinda bright in general,also the colors are too strong when in factory settings and i don't really know how to calibrate him corectly so i don't want to "stick my hands deeper".
Does the monitor brightness and contrast affect the eyes aswell or just the colors? I am sorry if i look like a stupid but i am very confuse. Can you guys please let me know what brightness and contrast should i use in combination with f.lux for long use? What is your brightness and contrast because i don't want to use f.lux and watch to not see anything. What do you guys think?
Thank you so much.
There's no way anyone can answer this because your eyes are unique to you. What's perfect for me may or may not be perfect for others. What's perfect for you may or may not be perfect for others too. All that matters is whether you're happy with your settings and how they let you feel at night. If you're feeling to alert, then reduce the brightness and use a warmer color temperature. Just experiment.
The brightness level of any light source still has quite an impact upon how "alerting" the light is, regardless if it's 100% pure red or not. The less light there is, the easier it will be for you to relax because the body is receiving less of a signal that it's time to be awake. How bright you set your monitor is all up to you and how it makes you feel. There is no right or wrong answer to this question and there never will be for anyone. It's just a matter of trial and error so that you are happy with what your settings are. Only you can answer this question.
I know that you wanted someone to tell you what settings to use, but that would not do you any good because only you can know what is best because only you have your eyes and only you have your brain. Y'know what I mean? It's all up to you. You are free to be "selfish" in this regard with your settings (you really have to be). Experiment until you have what you want. Just keep in mind that the brighter any light source is, the more alerting it will be. Yes, blue light more alerting than pure red light, but the brightness level (the amount of that light) plays a role too: an extremely bright red light can probably be more alerting than an extremely dim daylight-colored light bulb (a fairly blue light).
So, just listen to your body, trust your reactions. If you have to compromise color accuracy at night so that your monitor isn't making you feel too alert, then that's what you'll have to do. I have to do that (I use an extremely red color in f.lux), but it's worth it.

I appreciate a lot your honest and kind answer. What i want to know is if the high contrast affect the eyes too or just the brightness and color. I'm affraid that my monitor is too bright or there is too much color. Is there a perfect way to reduce the color since i don't have any option at the monitor or this is what f.lux does? Thank you again.

The main purpose and use of f.lux is to reduce the amount of blue light. Select a warmer color temperature, and enjoy. Use a lower monitor brightness at night in addition so that you can enjoy the least-alerting experience possible so that your melatonin production isn't delayed or prevented.
It's really as simple as this.
Since i have natural light in my room is there any problem if i have set f.lux at -5000k color temperature in daytime?
I think you're over-thinking this. You can use any settings you want. It doesn't matter, just as long as you're avoiding light at night that would interfere with your melatonin production and circadian rhythm.
I think you are right and i'm sorry for this many questions. I just want to know the right things because no one told me before and now i must confront the insomnia because of the use of pc... Thank you so much for your kindness,i do appreciate a lot.
You're welcome. I love f.lux and I always love meeting others who love it too! I am confident that you'll find settings that work for you so that when you are ready to go to sleep, you actually feel ready. If you don't feel ready when you want to be, then of course there are always numerous possible culprits (ranging from lifestyle, diet, chosen activity near bedtime, lack of exercise, stress level, etc., etc., etc.) - but one possible culprit in today's world is being exposed to too much blue light too close to bedtime. Like 100 years ago, that was never an issue. lol If it weren't for f.lux, no one would be able to safely use their computer right up until bedtime, and those people who are using f.lux today would otherwise still be wondering why they can't go right to sleep after they turn their computer off.
Of course, you still have to make sure your indoor lighting isn't too bright and blue. After all, what good is f.lux in a home that's lit by bright "Daylight" lights and super bright vanity lights in the bathroom, etc.? :) I use extremely low light at night. I also have a dimmer in the bathroom and brush my teeth and whatnot in a dimly-lit bathroom. I suppose if someone saw how I live during the last couple hours of my day, they'd think I'm a little crazy.
