Combat Digital Eye Strain: The 20-20-20 Rule

In today's digital world, most of us spend significant time staring at screens—whether it's computers, smartphones, or tablets. This can lead to digital eye strain, also known as computer vision syndrome.

What is Digital Eye Strain?

Digital eye strain occurs when your eyes are exposed to prolonged close-range focus on screens. Symptoms include: - Eye discomfort and fatigue - Blurred vision - Dry eyes - Headaches - Neck and shoulder pain

Why Screens Cause Strain

When viewing screens, we blink less frequently (up to 66% less), reducing tear production and causing dry eyes. Additionally, screens emit blue light, and the constant focus at a fixed distance can tire the eye muscles.

The 20-20-20 Rule

Here's a simple technique recommended by eye care professionals:

Every 20 minutes, take a 20-second break and look at something 20 feet away. This allows your eyes to relax and refocus at a distance, reducing strain.

Additional Tips

  • Adjust screen brightness to match your surroundings
  • Position your screen 20-26 inches from your eyes
  • Use artificial tears if experiencing dryness
  • Invest in blue light filtering glasses
  • Ensure proper lighting to reduce glare
  • Take frequent breaks throughout the day
