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.

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!
