Understanding and Preventing Computer Vision Syndrome


In the digital age, our lives are often dominated by screens. Whether we’re working, studying, or relaxing, we’re likely looking at a digital display. This constant engagement with screens can lead to a condition known as Computer Vision Syndrome (CVS), also referred to as Digital Eye Strain.

What is Computer Vision Syndrome?

Computer Vision Syndrome is a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader and mobile phone use. Symptoms of CVS might include headaches, blurred vision, neck pain, fatigue, eye strain, dry eyes, irritated eyes, double vision, vertigo/dizziness, polyopia, and difficulty refocusing the eyes. These symptoms can be further aggravated by poor lighting, glare on the digital screen, improper viewing distances, poor seating posture, and uncorrected vision problems.

How to Prevent Computer Vision Syndrome

Preventing Computer Vision Syndrome involves taking steps to reduce eye strain and increase comfort while using digital devices. Here are a few helpful tips:

  • Follow the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away. This can help reduce eye strain.
  • Adjust your workstation: make sure your screen is at a comfortable viewing distance and angle. The top of the screen should be at eye level or below so you look slightly down at your work.
  • Reduce glare: adjust the brightness of your screen and use window shades, desk lamps, or computer glasses to reduce glare.
  • Remember to blink: Blinking moistens your eyes and prevents dryness and irritation.

Consider Computer Glasses

One effective way of preventing CVS is through the use of computer glasses. These glasses are specifically designed to reduce eye strain when you’re looking at digital screens. They often include features like blue light filters, magnification, and anti-reflective coating.

Remember, if you’re experiencing CVS symptoms, it’s important to discuss this with your eye care professional. They can provide further guidance on how to relieve your symptoms and protect your eyes in the digital age.
