Causes of Computer Vision Syndrome

Several factors contribute to CVS:

1. Prolonged Screen Time

• Close viewing distances increase eye muscle fatigue

2. Poor Lighting or Glare

• Reflections on screens

• Bright overhead lights

• Outdoor glare on devices

3. Uncorrected Vision Problems

• Nearsightedness, farsightedness, or astigmatism can worsen strain

• Outdated prescriptions increase discomfort

4. Improper Ergonomics

• Screen height or distance not aligned with eye level

• Poor posture contributing to neck or shoulder strain

5. Reduced Blink Rate

• People blink less frequently while staring at screens, leading to dry eyes
