In the past minute alone, your eyes made as many as 240 quick movements called “saccades” (French for “jolts”). In your waking hours today, you will very likely make some 200,000 of them, give or take a few thousand. When you sleep, your eyes keep moving — though in different ways and at varying speeds, depending on the stage of sleep. A portion of our eye movements we do consciously and are at least aware of on some level: when we follow a moving bird or plane across the sky with our gaze, for instance. But most of these tiny back-and-forths and ups-and-downs — split-second moves that would make the Flying Karamazov Brothers weep with jealousy — are unconscious and nearly imperceptible to us. Our brain suppresses the feeling of our eye jumps, to avoid the sensation that the world is constantly quaking. Even when we think our gazes are petrified, in fact, we are still making eye motions, including tiny saccades called “microsaccades” — between 60 and 120 of them per minute. Just as we don’t notice most of our breathing, we are almost wholly unaware of this frenetic, nonstop ocular activity. The Real I.R.S.
