Computer Vision Syndrome (CVS) refers to eye and vision problems caused by prolonged screen use. Up to 90% of computer users experience symptoms.

Symptoms

  • Eye strain and fatigue
  • Headaches after screen use
  • Blurred or double vision
  • Dry, red, or irritated eyes
  • Neck and shoulder pain

Causes

Blink rate drops by up to 60% during screen use, causing dry eyes. Constant refocusing fatigues the eye muscles. Blue light from screens adds to discomfort.

The 20-20-20 Rule

Every 20 minutes, look at something 20 feet away for 20 seconds. This simple habit significantly reduces eye muscle fatigue.

Other Tips

  • Position your screen an arm's length away, slightly below eye level
  • Use anti-reflective coated lenses
  • Use lubricating eye drops throughout the day
  • Ask about blue light filtering lenses
