The 20-20-20 Rule for Eye Strain Relief

Learn the simple 20-20-20 rule to reduce digital eye strain and maintain healthy vision during screen work.

What is the 20-20-20 Rule?

Every 20 minutes, take a 20-second break and focus on something 20 feet away. This simple habit resets your eye muscles and reduces digital eye strain.

Why It Works

Long screen sessions cause your ciliary muscles to lock at a fixed focal distance. Looking far away relaxes these muscles and restores natural focus.

How to Implement It

Set a timer on your phone or use an app
Look out a window or at a distant wall
Blink fully during the break to re-wet your eyes
