In addition to f.lux and Night Shift as others have mentioned, I'm using a Mac menu bar app called Awareness [1] that reminds you to take breaks regularly. The Pomodoro style timing of 20+5 never really worked for me. I found a lot of my light tasks need 5–10 minutes while for serious dev tasks, 45 minutes of work is a better period of time to dig in deeply and get something done. Then I'll take a longer break of 10–20 minutes to balance that out. If I'm really in the zone at the 45-minute mark, I'll go ahead a plunge through a second 45-minute period without stopping.
