20-20-20 rule timer
Every 20 minutes, look at something about 20 feet (6 m) away for 20 seconds. Press Start, leave this tab open, and carry on working — the timer chimes when it is time to look away, counts the 20 seconds for you, then starts the next 20 minutes on its own.

Wellness only — not medical care. These are general eye-comfort and relaxation exercises. They are not medical advice, diagnosis, or treatment, and do not treat, cure, or prevent any eye disease. For any vision problem, see a qualified eye-care professional — do not delay or replace medical care. Sudden changes in vision, flashes of light, a shower of new floaters or eye pain need urgent care.
How to take a 20-second break
- When the timer chimes, look away from the screen at something about 20 feet (6 m) away — out of a window, or the far end of the room.
- Let your eyes rest on it for the full 20 seconds shown on the timer. Blink slowly a few times.
- Do not check your phone during the break — that is close-up focus again.
- The next 20 minutes start by themselves. Pause the timer when you step away from the screen.
Tip: if you have more than 20 seconds, try the two-minute palming or slow blinking exercise.
20-20-20 timer — questions
What is the 20-20-20 rule?
A simple habit for screen work: every 20 minutes, look at something about 20 feet (6 m) away for 20 seconds. It gives your eyes a regular pause from close-up focus.
Does the timer keep running if I switch tabs?
Yes. Leave this tab open and carry on working — the timer follows the clock, so it stays on time in the background. A browser that is saving power may hold a background chime back by up to a minute; ticking the notification box gives you a system pop-up as well.
Where is my break count kept?
Only in this browser, on this device. No account is needed (signing in is optional and does not move the count), nothing is sent anywhere, and the count starts again each day.
Is this medical advice?
No. It is a break reminder. For eye pain, headaches that keep coming back, or any change in your vision, see a qualified eye-care professional.
