Let’s keep it clear, most of us are hard users of computer tech these days (not to mention millennials, who are pretty much all-native users). And it’s not an optional decision anymore. 

iMacs and MacBooks, together with smartphones and tablets, vigorously became dominant tools not only for work but also for the most part of our everyday interactions. 

There are no arguments in terms of how helpful and life-changing it is. But there are some worries, actually, when it comes to a possibility of harmful impact on mental and physical health. 

The first thing that comes to mind is potential problems with eyes due to visually intense tasks such as focusing on computer monitor. This risk becomes exponential if you frequently work with computer at night-time or in low-light. As a result, it could also cause some difficulties with your sleep.

It’s sad. Yup. But there’s some kind of solution in fact. While investigating the best Mac apps, we discovered f.lux, an elegant and simple way to deal with “heavy-computer-usage” problems. And, nope, it’s not a promoted story.

What it’s all about

f.lux is a lightweight, yet mighty piece of software that adjusts your display’s color temperature depending on time of day and your location. The app was designed on a mission to reduce eye strain during late-time computer use and breakdown of your sleep patterns. 

Asthenopia or eye strain is an ophthalmological condition that manifests itself through nonspecific symptoms such as fatigue, pain in or around the eyes, blurred vision, headache and occasional double vision. Symptoms often occur after reading, computer work, or other close activities that involve tedious visual tasks.Wikipedia

How it works

All you need to do is choose your location based on its geographic coordinates, ZIP code, or name. f.lux then automatically calibrates your display's color temperature to the time of the day, based on sunrise and sunset. 

At sunset, it will gradually change the color temperature to a warmer (read “safer” to an eye) color, and restore the original at sunrise.

Tell f.lux what kind of lighting you have, and where you live. Then forget about it. f.lux will do the rest, automatically.f.lux

Yet, f.lux settings could be modified for specific apps or activities. For example, there’s a mode for watching movies.

F.lux is a free app for Mac, Windows, and Linux computers that makes the colour of your display adapt to the time of day.
