By default, our computer, iPhone or iPad screen are designed in a way to display optimum color during daylight, but apparently it’s not true for the night. It seems that very often in the night or early morning, our eye easily get strained or flashed by the computer screen. Although technology is the culprit in this case, but it’s also the fix always.
If you have noticed, our screen typically has a cool blue undertone at all the times. This blue tone works fine during the day as it mimics the tone of daylight or sunlight. As a result, the blue light would unconsciously and consistently signal our brain to stay awake by stimulating certain hormone. It’s similar to the Red Bull energy drink in the reality. But we just don’t drink Red Bull when we wanted to sleep, do we?
So in order to rid of the blue light at certain time of day, we can either do it manually or efficiently using a free software called F.lux. It’s a install-and-forget software that will tune the screen color automatically based on you geographical location. F.lux is a very light software that handled everything in the background that you don’t even notice it’s existence after initial setup. It just works quietly and brilliantly!
f.lux makes your computer screen look like the room you’re in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.
The installation is a snap. For Window and Mac, just download F.lux and setup accordingly by telling your location and the type of ambient lighting (Don’t worry, you can always change it afterwards). After that you can have a neat preview of how F.lux will do the color adjustment to your computer screen throughout a day. Additionally, you can also choose to disable the color adjustment feature anytime when you want to have the normal color display, particularly for doing color-sensitive work.
For iPad and iPhone, it required a little more steps due to the confined iOS ecosystem. You need to jailbreak the devices to download F.lux from Cydia. After that it’ll work the same as the desktop version.
My Experience with F.lux
I have been using F.lux for almost 2 months, and I’m urged to share this brilliant piece to everyone. Without exaggeration, F.lux has practically improved my sleeping quality and unexpectedly prolonged the battery life of my laptop. Although sometimes I would disable the feature when watching movie or photoshopping, still I can’t live without F.lux. You should really give it a try too!
