What Is the 20 / 20 / 20 Rule?

The 20 / 20 / 20 rule is a simple and effective method to prevent digital eye strain. It’s recommended by eye doctors as a way to protect your vision during long hours of screen time. The rule is easy:

  • Every 20 minutes,
  • Look at something 20 feet away,
  • For 20 seconds.

Following this habit regularly can reduce dry eyes, headaches, and blurred vision — all common symptoms of computer vision syndrome. This free eye strain timer automates the process so you don’t have to think about it.

How This Eye Health Timer Works

The 20 20 20 timer runs in a loop:

  1. 20 minutes of screen work.
  2. 20 seconds to look away and focus far away.
  3. 20 seconds to relax your eyes and blink slowly.

It’s perfect for anyone who works at a computer or spends hours on devices. Use this 20 minute vision break timer throughout your day to give your eyes the regular rest they need.
