As dusk approaches however, your screen gradually (if you have selected the slow setting) changes to a warmer, easier on the eye, colour setting. F.lux in useĭuring the daytime you won’t notice any difference to your screen, unless you prefer to change the default daylight setting of 6500K. I prefer slow, as you barely notice when the change happens. You can choose either a slow or fast transition between the day and night settings. You can select Tungsten, Fluorescent, Halogen or choose your own custom value by adjusting the temperature sliders. Next you select what type of light you want your screen to replicate at night. To set it up, the first thing you need to do is add your location, then the app calculates the time of sunset and sunrise wherever you are.

This doesn’t cause any issues in the daytime, but at night, this blue light limits the production of melatonin. In layman’s term, the bright light from your laptop/iPhone/iPad etc screws up your sleep-wake cycle. Using computers at night wrecks your sleepĬomputer screens – and that includes smartphones and tablets – emit light in the blue part of the spectrum.

When the light starts to fade at night, our bodies start producing melatonin, aka the ‘sleepy hormone’.Īs morning approaches, the daylight becomes a signal to stop producing melatonin, which makes us feel alert and awake. It’s a beautifully balanced symbiotic relationship with nature. Human beings have evolved alongside these daily light patterns, developing biological mechanisms to trigger sleep and wakefulness. As the day progresses, the colour temperature changes – think of the difference between a bright clear morning and a golden sunset. These colours can be represented on a ‘temperature’ scale, measured in Kelvin(K). Visible light is made up of different wavelengths which our eyes perceive as colour. In order to fully benefit from using F.lux, it’s useful to know a little of the science behind this app. I still don’t get it, why do I need F.lux?

Whilst this gives you a very broad idea, many people miss the point completely. The strapline for the software is “ Better lighting…for your computer“.
