Looking at a screen keeps your eyes fixed at a near distance and you blink less. A common tip is 20-20-20: every 20 minutes, look about 6 m away for 20 seconds. Use these pictures as a 20-second cue. If there is a window, look outside. If not, rest your gaze on the farthest point in the picture and blink slowly a few times.
