👁️ 20-20-20 Eye Rest Timer

🔬 Why the 20-20-20 Rule Works

The 20-20-20 rule is recommended by the American Optometric Association to reduce digital eye strain and Computer Vision Syndrome (CVS). When you focus on a screen for extended periods, your eye muscles remain contracted, leading to fatigue, dryness, headaches, and blurred vision.

Looking at a distant object (20 feet or more) allows your eye muscles to relax and helps restore the tear film on your eye surface. Taking these regular breaks every 20 minutes significantly reduces eye strain symptoms and helps prevent long-term vision problems.

Computer Vision Syndrome affects 50-90% of computer workers. Simple preventive measures like the 20-20-20 rule can dramatically improve comfort and productivity while protecting your eye health.
