Eye Break — the 20-20-20 Rule
Every 20 minutes at a screen, look at something 20 feet away for 20 seconds — the one rule that resets the eye's focusing muscle before fatigue sets in.
Every 20 minutes at a screen, look at something about 20 feet away for 20 seconds — the one rule that lets the eye's focusing muscle reset before fatigue sets in. Screen work cuts blink rate, which dries the surface of the eye; the prolonged near focus tenses the ciliary muscle that controls lens shape. The far gaze releases both.

The protocol
- Set a recurring timer at 20-minute intervals. Do not rely on noticing — by the time eyes feel tired, the break is already overdue.
- Look at any object at least 20 feet away (a window, a wall across the room, a tree outside). The distance is what matters, not what you look at.
- Hold the far gaze for 20 seconds. Blink naturally.
- Pair with standing up — the break costs nothing extra and gets you off the seat.
Where it fits in a day
- Any sustained screen session. Office work, coding, writing, reading on a device — the muscle fatigue mechanism is the same regardless of content.
- Before video calls. A 20-second far gaze immediately before a call drops screen-induced eye strain going into the call.
- Evening. Particularly useful in the last 90 minutes of screen use, when combined with lower screen brightness.
Why it works
- Ciliary muscle release. Sustained near focus contracts the ciliary muscle continuously; the far gaze lets it relax fully.
- Blink rate restoration. Blink rate drops significantly during screen use; a deliberate break restores it briefly and re-wets the tear film.
- Attention reset. A 20-second gaze shift interrupts default-mode rumination and provides a genuine micro-break before the next task segment.
