I never thought I felt eye strain from looking at big, bright screens all day—I thought my young eyes were invincible. Then I started getting sharp headaches at the end of every day, and I realized I needed to change something.
I decided to finally take the jump and start using f.lux. f.lux is an app that changes the color temperature of your display, adapting the light you see to the time of day, which helps to reduce eye strain. There’s a new beta out for Mac that brings some really fantastic improvements and enhancements (don’t worry, there’s a Windows version too!).
In the morning and afternoon, you’ll see the blue-ish colored light that your screen normally pushes out. As the sun sets, the light will shift to a more reddish color, and when night falls, it’ll become an even deeper red. Every color step is customizable, so you decide how red-shifted you’d like each phase to be—I like mine on the deeper end of the scale.
It’s normal to see blue light during the day, but as it gets darker, that light is harsh on our eyes. Red light is easier on your eyes, especially at night—it’s why red lights are used to preserve vision at night.
When I tell people in our industry about f.lux, I often hear something like, "But what if I’m doing color-sensitive work?" The newest f.lux beta has a feature that allows you to disable f.lux in certain applications. As you switch into an application where you’ve disabled f.lux, your screen will slowly transition to normal colors. The smooth transition will help prepare your eyes for the blue wave of light you’re about to get hit with, so it’s not too jarring.
For anyone who spends hours a day looking at a screen, f.lux is a must-have. We spend a lot of time and effort making sure we use ergonomically-correct keyboards, chairs, and desks, so it’s time we gave our eyes a similar level of treatment.
