What is Computer Vision Syndrome? Symptoms, Causes & How to Prevent It

August 12, 2025

What is Computer Vision Syndrome?

Computer Vision Syndrome (CVS), also known as digital eye strain, is a group of eye and vision-related problems resulting from prolonged use of computers, tablets, e-readers, and Smartphone. CVS meaning encompasses discomfort and visual issues that arise from staring at digital devices for extended periods. When you spend hours in front of a screen, your eyes work harder to focus, often leading to various computer eye issues.


How Prolonged Screen Use Affects Your Eyes

Long periods of screen exposure require our eyes to constantly refocus and move, stressing the eye muscles. Digital screens also emit blue light, contributing further to eye fatigue and discomfort. Blinking becomes less frequent, causing dryness.


Who Is Most at Risk?

  • Students: With remote learning and homework, screen time is at an all-time high.
  • Office Workers: Daily computer-based tasks can lead to digital eye strain.
  • Gamers: Hours of uninterrupted game play significantly increase risk.


Common Symptoms of Computer Vision Syndrome

The most frequent eye strain symptoms include:

  • Blurred or double vision
  • Dry or irritated eyes (dry eyes from computer use)
  • Headaches, neck and shoulder pain
  • Difficulty focusing after screen use
  • Increased light sensitivity

If you notice these signs of computer vision syndrome after using screens, you may be experiencing CVS.


Main Causes of Computer Vision Syndrome

Computer Vision Syndrome is often triggered by:

  • Prolonged screen time: Using mobiles, laptops, or TVs for long stretches increases risk (screen time effects on eyes).
  • Poor lighting or glare: Inadequate lighting or glare on the screen strains the eyes.
  • Incorrect posture or screen distance: Poor ergonomics impact both posture and eye health.
  • Lack of regular breaks: Extended periods without breaks give the eyes little chance to recover.
  • Blue light exposure: Screens emit blue light, which impedes comfortable vision and may disrupt sleep patterns.


How to Prevent or Reduce Computer Vision Syndrome

You can prevent CVS and keep your eyes healthy with these eye care tips for screen users:

  • Follow the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for 20 seconds.
  • Use anti-glare glasses or screen filters: These can block reflections and blue light protection glasses minimize impact.
  • Adjust screen brightness and contrast: Match the light level with your surroundings.
  • Practice eye exercises: Simple movements can relax eye muscles.
  • Create an ergonomic workspace: Ensure your chair, desk, and screen encourage good posture and are at the correct height and distance for your eyes.


When to Seek Medical Help for CVS

Reach out to an eye doctor for computer use if you experience:

  • Symptoms that persist despite breaks
  • Frequent changes to your prescription glasses
  • Eye pain or sudden vision changes
  • Difficulty focusing or persistent discomfort

Regular eye checkups and specialist support are vital for managing screen-related eye issues. Some optometrists offer a CVS eye test to assess the extent of digital eye strain.

Computer Vision Syndrome is increasingly prevalent in our digital age, but with awareness and preventive strategies, you can minimize its impact and maintain healthy, comfortable vision.
