How the Screen Time Break Reminder works
- Set your work interval and break duration, or keep the classic 20-minute / 20-second defaults.
- Click Start and keep working — the timer counts down in the background of the tab.
- When the work interval ends, the display switches to a break prompt; look away from the screen until it ends, then work resumes automatically.
Why eye breaks matter
Sustained close-up screen focus reduces your natural blink rate and keeps your eye's focusing muscles locked in one position, both of which contribute to digital eye strain — dryness, fatigue, and blurred vision by the end of a long work session.
FAQ
What is the 20-20-20 rule?
It's a widely recommended habit for reducing digital eye strain: every 20 minutes of screen work, look at something roughly 20 feet (6 meters) away for at least 20 seconds. It gives your eye's focusing muscles a brief rest from sustained near-focus work.
Does the timer keep running if I close the tab?
No — the timer only runs while this page is open in your browser. It's a lightweight reminder tool, not a background service, so it resets if you navigate away or close the tab.
Can I customize the intervals?
Yes — while the classic rule is 20 minutes of work and a 20-second break, you can set any work interval and break duration that fits your workflow before starting the timer.
