f.lux Reviews

Ok, but has very odd performance issues.

about f.lux · · Helpful Not helpful 1 Helpful

I have used this software for a while, and, while it does help me get some better rest, it has some serious performance issues when it comes time to transition between daytime and nighttime, and vice-versa. In addition, on certain video hardware like mine (Intel or NVidia graphics), the system will drop one frame out of 60 every second, on the dot. If you are a causal user this is excusable, but some users (PC game players, for example) may dislike it due to to this. This is a known issue, yet I haven't seen any solutions/updates pushed to this program, and the suggested workaround is to put the program into safe mode. At the end of the day, if you are a casual user, you should be able to use this no problem. Gamers and other heavy-duty users should look elsewhere for a better solution.

Take a look at LightBulb (Small LightBulb iconLightBulb). It focuses on having minimum performance impact and is very customizable.

Resets Windows Calibration

about f.lux · · Helpful Not helpful

This app completely resets Windows calibration settings and the developers aren't willing to fix it even though the issue has been oepnly addressed on their forum multiple times. This makes it completely unusable for me since all my black colors turn to grey and if you're using Windows calibration, you won't be able to use it neither.

I don't get it

about f.lux · · Helpful Not helpful

This application makes my eyes sore and my vision gets blurry when the app comes into play in the evenings. I really don't understand the reason behind so pervasive praising of this program. Dammit, why not just manually adjust the brightness of the monitor at night or, even better, aim to use your computer only during daylight hours? Why would someone rely on some piece of software that's basically aimed to decide what's best for eyes without even knowing the model of the monitor or anything about its settings?
And that expression from the description cracks me up: "During the day, computer screens look good—they're designed to look like the sun." Designed to look like the Sun you say? No sh*t. Last time I tried gazing at the unclouded Sun for more than a couple of seconds I felt like my eyes are going to die on me. I am sure as hell I haven't ever experienced anything similar with any of my bloody computer screens.

It's not for your eyes, it's for the hypothalamus. So the brain doesn't think it's morning because of the blue light emitted from the screen. We only have natural blue light in the morning and a warm light later in the day. It takes an hour extra to fall asleep after you see blue light than if you didn't. You can't change your settings to mimic natural lighting conditions every few minutes...
If it bothers your eyes that much you might have a problem and should go get them looked at.
I know it's an old post... but still...

There are lots of other more significant factors that define how fast one falls asleep (and the quality of sleep) than being exposed to some light before going to bed. For example if you've been up for 24+ hours straight, you will fall sleep no matter what, even if the sun is shining nicely through your window. Unless of course you have some serious sleep disorder, but flux aint gonna help there moreover.

I don't care for what exactly Flux is, but the eyes do take some toll most likely than not, because flux makes the picture less legible and harder to make out.

This is very dear to me becuase I have several small and big issues with my eyes. This application has made me enjoy my long PC-days. I need to be online for +13h a day and the blue screen of my PC has been killing me and making me go to bed early because my eyes just didn't feel alright after only 5-8h online, even with screen protectors. Now, mind I sit in a humidified and well maintained room- still, they felt dry, heavy and whatever... this tool, this is just... I'm just so thankful for this. I can only praise it! A must-have for people who spend their days with their machines turned on and stared at for X hours every single day!

I have used F.lux for a long time and I'm so thankful to the guys at F.Lux. It works, it's free... it works and that's all that matters!
