The 20-20-20 technique is a simple method to reduce eye strain, particularly for people who spend extended periods working on computers or digital screens. The technique suggests that every 20 minutes, you should look at something that is 20 feet away for at least 20 seconds

Here's how it works:

1. 20 Minutes: Every 20 minutes of screen time, take a break.

2. 20 Feet: Focus on an object that is at least 20 feet away from you.

3. 20 Seconds: Hold your gaze for at least 20 seconds to give your eyes a chance to relax.

This technique helps relieve eye strain, reduce discomfort, and prevent digital eye strain or "computer vision syndrome."

It encourages regular breaks, allowing your eyes to refocus and avoid fatigue.
