Computer screens are designed to look like the sun which is fine for the most part of the day. On my evening/night studio sessions, however, I’ve been struggling with the harsh blue-ish color of my screen, occasionally resulting even in headaches.
f.lux is a brillant FREE app for Mac, Windows, Linux and jailbroken iOS devices that changes all that – it adapts your computer’s display to the time of day with its 3-level settings (daylight, sunset and night). Just enter your location and forget about the app. Or you can modify each setting to exactly match your room lights.
I really feel this app is a game changer and you should definitely try it out if you work on your computer late in the evening or at night.
