How to Make Your PC Easier on Your Eyes
What a clever idea. F.lux is a freeware program that adjusts the color of your screen depending on the time of day. So at night, F.lux makes the screen look warmer and less glaringly blue than during the day. The end result is a screen that is much easier on the eyes.
F.lux works by changing the color temperature of your display. The default setting is 3400K for night and 6500K for daytime. This can affect color sensitive work such as editing digital photographs but there is a disable switch that allows you to turn F.lux off.

The change in color is automatic based on estimated sunrise and sunset times for your location. The location is only a guess based on your time zone settings but you can enter an exact latitude and longitude if you wish.
Versions are available for Windows XP/Vista, Mac OS X and Linux. The Windows download is 545KB.

This program is innovative and really works. This is a great find. Thanks, Gizmo!
I like it but F.lux doesn't retain its settings when coming out of standby in the evening. This happens on 2 Acer laptops and a Dell desktop. Left a note on the developer's site but can't see my comment listed now - disappeared into the ether.

Excellent program and makes a real difference if using the PC a lot at night, or often all night in my case and has been installed on all my laptops and tablets. For those complaining about it being too pinkish, which I did at its basic install settings, go into settings and fiddle with the colour temperature slider to find a setting that suits while still giving the advantage it offers. For instance, I find a temperature of around 5000K works best for me at night. I find my eyes not getting so tired at night since I started using it.
I also found the developers quick to reply as well as being appreciative of feedback and suggestions and they said that they were working on the next version.
Sorry, this may be OT but my worst problem is with bright white web page backgrounds sort of like this one.
Adjusting monitor settings not good here. Suggestions please?
Great idea, terrible results. Hated the color and dim screen results!
One of my friends found a trojan in this - F-Secure flagged it for him. He and I are both freaked out right now... anybody want to comment?
Very good find.. Its clean..
Never thought of something like this. I've known for literally decades that PC screens, flourescent lights, and people's eyes don't mix well. The refresh rates are not anything like one another, and the tiny muscles in the eyes fatigue quickly. LCD screens have helped, but the color and brightness issues are still there. I even have a pair of reading glasses that are tinted pinkish-brown to use just for PC work. This program takes care of all of that! Great idea, and already using it. Works fine, and no issues with any scans I gave it.
Apparently well designed and should be helpful. D.D.
Well, AVG has flagged it as a threat... Has nobody else had the same thing?
My AVG updates may need up dated but my copy cleared it. Further I scan any downloaded software files with other security software before opening and nothing appeared? D.D.
No, I've uploaded the setup file to VirusTotal and it shows up totally clean.
As for the .exe file itself, here's the result: http://www.virustotal.com/analisis/be64bc8bd856483e20df68aa33d40ef303415...
The program still should be safe though. False positives do exist (especially for not so popular programs).
Yes, Online Armor Firewall identified it as a keylogger. I uninstalled it.
anyone have a comment on this? I would like to try it out.
I would also recommend downloading the ClearType Powertoy, it makes text much easier on the eyes, in combination with F.lux, it makes for a very easy-on-the-eyes computer.
Totally agree about Cleartype. It works well in Vista too, although you might not think so as MS don't seem to promote that.
Fantastically simple. May take a few days to get use to the pinkish hue but certainly does what it says. Easy to change the level using the Halogen / Florescent / daylight slider.
This is my "Easy on the Eye's Setting's" webpage for XP. For Vista just change the DPI_ 96 to 120.

I also use Opera's 'Fit-to-Screen" feature. It let's you increase text size however large you want and Opera adjusts the webpage to fit the screen_no side scrolling needed.
Cool....... Thanks........ man
Just downloaded and tried f.lux for the first time today. I like it already. Neat idea. And very useful since I stare at a computer screen almost every evening. Thanks for pointing it out.
Here is a manual set program I like...
ssOverlay (the ss stands for Scotopic Sensitivity), places a coloured overlay onto the screen. The colour and transparency levels can be adjusted to suit the user.

Well, it works fine for me. This is posted at 0210 and my eyes are tired. Great for just working on text, made me realise when you disable it how bright the screen is. No wonder my eyes hurt. Will have to see how it works in my room in full daylight, but at the moment, well done Gizmo.
Now this is something new (for me at least). Seems to work fine.
I'm sorry but that was a horrible experience, I hated the settings it suggested, I dunno, maybe my eyes are too sensitive but I REALLY didn't like the results :s
Is it not possible to make the settings variable by the sunlight and/or cosmatic light received by the camera motly build in laptops and/or cameras used by users who video-chat?
Sorry, it was posted by me but I forgot to logon. :-)
peter ... tried to fix that... shall i delete this post.
One Anonymous comment (that got lost in the wires) says:
"My opinion is still that the time of day is far to
crude an estimator of the fitting colour temp. It should definitely have a configuration wizard at first and also have a quick way of changing (right click tray icon) between various setting sets. Also it should warn carefully that getting the colour balance wrong or changing it from the manufacturer ICC colour profile, will lead to inaccurate colour reproduction and you may get for example prints in a
colour you did not expect."
This will probably come in the folowing versions.
Interesting - I'll try it for a few days
this sounds good but it seems too warm for my lcd maybe? Here the whole screen turns yellow, even red and it looks weird...And i noticed a few tweaks I can do but don't know what exactly do them mean here, like halogen, fluorescent. No help file included and their site doesn't say much about the settings. I'm confused but will try for a few days more to figure it out.
Great program , especially for light sensitive eyes/balls. This program should be mandatory on every PC right from the get go. Very , very bee-u-tiful. It is a "must see" program- pardon the pun - just happy and having fun. " FLY PELICANS FLY!!!"
This is exactly what I have been wishing for!! I have not used it yet, having just downloaded it through Gizmo TechSupportAlert Further comment will follow. Best wishes, Bob Bowen South Africa.
"The location is only a guess based on your time zone settings but you can enter an exact latitude and longitude if you wish."
I just want to say that you can give it a zip code as well.
Great program. I use it. I hardly even notice the color change, but if I turn it off I realize how much it was helping.
Thanks for this tasty treat! Hoping it won't conflict w/ Calibrize utility, but seems stable so far. Thought I'd turn it off for now and check it in daylight later, but almost burnt out my retinas!
This will probably become one of the "must-have" programs that gets installed right away on new machines and those of all my friends...
