Suppose you’re spending long hours in front of a screen and noticing tired eyes, headaches, or blurry vision. In that case, you may be experiencing Computer Vision Syndrome (CVS) — a common yet often overlooked condition affecting millions of digital device users.

What Is Computer Vision Syndrome?

Computer Vision Syndrome, also known as digital eye strain, is a group of eye and vision-related problems that result from prolonged use of computers, tablets, smartphones, or e-readers. According to the American Optometric Association, CVS affects around 50% to 90% 

of people who use a computer daily.

When you focus on a screen for extended periods, your eyes have to work harder. Poor lighting, screen glare, incorrect posture, and improper viewing distances can all contribute to the development of this condition. 

Common Symptoms of Computer Vision Syndrome

Experiencing any of these symptoms? You’re not alone:

• Eye strain or discomfort

• Blurred or double vision

• Dry, itchy, or watery eyes

• Neck and shoulder pain

• Headaches

• Difficulty focusing on distant objects after screen time

Symptoms often worsen with extended screen use and tend to improve after rest.

What Causes Digital Eye Strain?

Several factors combine to strain your eyes during screen time:

• Reduced Blink Rate

People blink about 66% less when using digital screens. Less blinking means your eyes don’t stay as moist, leading to irritation and dryness.

• Improper Lighting and Glare

Overhead lighting or sunlight reflecting on your screen can create glare, which forces your eyes to work harder.

• Poor Posture and Viewing Distance

Sitting too close or too far from your screen, or using a chair and desk that don’t support your posture, can add stress to your eyes, neck, and shoulders.

• Uncorrected Vision Problems

Even minor refractive errors can be magnified during screen use, especially if you’re not wearing the right prescription or protective lenses.

Tips to Prevent and Manage Computer Vision Syndrome

Reducing the impact of digital eye strain is possible with a few mindful adjustments:

Follow the 20-20-20 Rule.

Every 20 minutes, look at something 20 feet away for at least 20 seconds to give your eyes a much-needed break.

Optimise Your Workstation

• Keep your screen at arm’s length (about 25 inches)

• Position it 15–20 degrees below eye level

• Use an anti-glare screen filter

• Ensure ambient lighting isn’t too harsh or too dim

Use Blue Light Filtering Eyewear

Wearing blue light-blocking glasses can help reduce the strain caused by prolonged exposure to screen-emitted blue light, especially in the evening.

Adjust Your Screen Settings

• Increase text size and contrast

• Use dark mode when possible

• Reduce screen brightness to match ambient lighting

When to See a Professional

If you continue experiencing discomfort despite following best practices, it’s time to consult an eye care professional. They can:

• Assess your vision

• Recommend specialised eyewear for digital use

• Check for underlying conditions contributing to your symptoms

Regular eye exams are key — especially if you spend 6+ hours a day in front of a screen.

Conclusion

Computer Vision Syndrome is a modern-day issue that can seriously affect your quality of life if left unaddressed. With mindful habits, ergonomic improvements, and the right eyewear, you can protect your eyes and maintain long-term comfort — even in our screen-heavy world.
