I don't get it

Comment by Azazel
about f.lux May 2014

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.

Well I must say that the app developer is awesome! I sent a twitter message to him regarding the problems with the new macbook pro and within two hours I received a reply with a link to a beta build that fixed the issue. He even sent me another build immediately after where he fixed another issue he found. So all is well again, however the version with the fix is not yet publicly available. If you happen to have this same problem, check out @herf's feed (the developer) on twitter and you will find the link to the beta build.

This app is great... I've had problems with insomnia for as long as I can remember. Within 30 minutes of downloading and installing this app last night (@4 in the morning), I fell asleep with my laptop on the couch. There's definitely something to this "blue" spectrum thing.
