The 20/20/20 rule is a simple strategy to prevent eye strain for those who spend long hours in front of a screen. Here's how the original rule works:
What is the 20/20/20 Rule?
The 20/20/20 rule involves:
- 20 Minutes of Screen Time
- 20 Seconds of Eye Rest
- Looking at Something 20 Feet Away
Step 1: 20 Minutes of Screen Time
Work or use your screen for 20 minutes. This is a manageable period to stay focused while allowing regular breaks to prevent eye strain.
Step 2: 20 Seconds of Eye Rest
After 20 minutes of screen time, take a 20-second break to rest your eyes:
- Look Away: Focus on something at least 20 feet away. This helps relax the eye muscles.
- Blink: Blinking helps keep your eyes moist and reduces dryness.
