The 20/20/20 Rule

Your eyes deserve
a real break.

Every 20 minutes, look at something 20 feet away for 20 seconds. Backed by optometrists. Takes zero willpower when you have a timer.

Why the 20/20/20 rule works

When you stare at a screen, your blink rate drops by up to 66%. The 20/20/20 rule forces your ciliary muscles to relax and your cornea to re-lubricate.

🔬

Clinically studied

Research published in Ophthalmic & Physiological Optics shows significant reduction in eye strain symptoms with regular 20-second breaks.

😌

Muscle relaxation

Your eyes' focusing muscle (ciliary body) locks up after sustained near work. Looking at a distant object forces it to relax completely.

💧

Tear film reset

Each blink recoats your cornea with tears. During screen use, involuntary blinks drop by over half — causing dryness and blur.
