What Is Computer Vision Syndrome and How To Reduce Eye Strain

If you spend hours in front of a screen every day, you may have experienced dry, tired eyes or even headaches by the end of your work session.

These are common symptoms of computer vision syndrome (CVS).

CVS is a condition caused by prolonged digital screen use. CVS, also known as digital eye strain, results from the increased visual demands of screens, leading to discomfort and vision problems.

Symptoms of CVS can include eye fatigue, blurred vision, difficulty focusing, headaches, and even neck and shoulder pain. The more time you spend in front of a screen without breaks, the more likely you are to experience these issues. But why does this happen?

Read on to learn more about CVS, its causes, and what you can do to prevent it from affecting your sight and quality of life.

How Screen Time Affects Your Eyes

Reading or working in front of a screen may not seem like a problem. However, be warned:

Unlike reading from a printed page, looking at a digital screen requires more effort from your eyes. The text on screens isn’t as sharply defined, contrast levels fluctuate, and glare from lighting or reflections can make it harder to see clearly.

Couple this with the fact that we tend to blink less when staring at screens, and you get a recipe for dryness and irritation.

Another contributing factor is prolonged exposure to blue light. Digital screens emit a high-energy visible (HEV) light that can contribute to eye strain and disrupt sleep patterns.

Without proper precautions, hours of screen time can take a toll on your vision and overall eye health.

Simple Ways To Reduce Eye Strain

We understand that many today need to work in front of computer and phone screens. However, that doesn’t mean you can’t do anything to prevent eye strain.

By following these actionable tips, you’ll be able to prevent CVS and other visual problems associated with prolonged time in front of screens.

Follow the 20-20-20 Rule

One of the most effective ways to reduce digital eye strain is by following the 20-20-20 rule. Every 20 minutes, take a 20-second break to look at something 20 feet away. This allows your eye muscles to relax and reduces fatigue from prolonged focus on a screen.

Adjust Your Screen and Workspace

Proper ergonomics can make a significant difference in reducing strain. Position your screen so that the top of the monitor is at or just below eye level, about 20–28 inches from your face. Make sure there’s no glare from overhead lights or windows, and consider using an anti-glare screen if needed.

Optimize Your Lighting

Poor lighting can worsen eye strain. Avoid working in a dimly lit room or in harsh, overhead fluorescent lighting. Instead, use soft, indirect lighting that minimizes glare while keeping the room bright enough for comfortable reading.

Blink More and Stay Hydrated

Since we blink less when looking at screens, our eyes can become dry and irritated. Make a conscious effort to blink more often and stay hydrated to maintain proper tear production. If you still experience dryness, lubricating eye drops can help.

Consider Computer Glasses and Blue Light Filters

To further protect your eyes, computer glasses with blue light filters can reduce the strain caused by prolonged screen exposure.
