The complex is a set of exercises during which you have to look in the directions indicated by the dot.
The dot only shows the direction - move your gaze as far as it will go, but not too far.
At the extremes, hold your gaze for a second.
After each exercise, you can gently squeeze your eyes or blink for a couple of seconds to help your eyes relax.
Total exercise time: 3 minutes and 25 seconds.
