Understanding the 20-20-20 Ergonomic Rule
The 20-20-20 rule is simple yet powerful: Every 20 minutes, focus your eyes on an object at least 20 feet away for a minimum of 20 seconds.
When viewing close-up monitor screens, your eye ciliary muscles remain continuously contracted. Looking at a distant object allows these focal muscles to relax completely, reducing ocular strain, tension headaches, and blurred vision.
