In today’s digital world, many spend long hours in front of computer screens, whether for work, school, or leisure. This prolonged screen time can affect eye health, leading to discomfort and strain. Known as Computer Vision Syndrome (CVS), this condition isn’t just a single issue—it includes a range of symptoms like eye fatigue, dryness, and headaches. 

Research suggests that between 50% and 90% of people who use screens regularly experience some form of CVS. And it’s not just working adults—children who use tablets or computers in school can also be affected, especially if their screen time is paired with poor lighting or improper posture. 

Abasa Optical understands the effects of digital eye strain and is committed to helping you find practical solutions to keep your eyes comfortable and healthy. You can book an appointment online or visit our Surrey, BC, clinic for personalized eye care.

What is Computer Vision Syndrome?

Computer vision syndrome, or digital eye strain, is a collection of symptoms when you spend extended periods using computers or other digital screens. You may experience eye irritation, blurry vision, headaches, and general discomfort. While these symptoms are temporary, they can interfere with your daily activities and productivity.

Although computer vision syndrome isn’t a serious condition, it can be frustrating. Proper management can help relieve your symptoms, but if they persist, they may affect your work performance or prevent you from enjoying screen-related activities. That’s why it’s important to understand the risk factors and take steps to prevent or manage this common issue.

How Common is Computer Vision Syndrome?

Computer vision syndrome is widespread, affecting an estimated 60 million people worldwide. Before the COVID-19 pandemic, at least half of all adults experienced this condition. However, with increased screen time for work and socializing during the pandemic, that number rose to 78%. Children were also impacted, with research suggesting that 50% to 60% experienced symptoms during this time.

How Do Computers Affect Vision?

Computer vision syndrome (CVS) is similar to repetitive strain injuries like carpal tunnel syndrome. It develops because your eyes repeatedly follow the same patterns, and the longer this continues, the worse it can get.

When using a computer, your eyes constantly adjust—moving back and forth while reading, shifting focus between the screen and documents, and processing changing images. This puts significant strain on your eye muscles. Unlike reading a book or paper, screens introduce extra challenges like contrast, flickering, and glare. Studies show we blink far less when staring at a screen, leading to dry eyes and occasional blurred vision.

If you already have vision issues, wear the wrong prescription, or need glasses but don’t have them, you may experience even more discomfort. As you age, computer work becomes tougher. Around age 40, the eye’s natural lens starts losing flexibility, making it harder to focus on objects at different distances—a condition known as presbyopia.

What Are the Symptoms?

Computer vision syndrome can cause various symptoms, with eye discomfort being the most common. You may experience:

  • Dry, watery, itchy, or burning eyes, sometimes feeling like there’s something in them.
  • Blurred vision that comes and goes, especially when shifting focus between near and far distances.
  • Sensitivity to bright lights.
  • Difficulty keeping your eyes open.
  • Headaches often felt behind the eyes.

Many people also develop aches and pains in other areas, mainly if their posture isn’t ideal or they strain their necks to view their screens. This can lead to discomfort in the:

  • Neck
  • Shoulders
  • Back

How to Relieve Computer Vision Syndrome?

Computer vision syndrome treatment involves managing dry eyes, correcting vision, and adjusting your routine and workspace. Your eye care provider may recommend combining these approaches to ease symptoms and prevent them from returning.

1. Managing Dry Eyes

Prolonged screen time can cause dryness and irritation. To keep your eyes comfortable, you can:

  • Use artificial tears to add moisture.
  • Make a conscious effort to blink more often.
  • Try prescription eye drops if needed.

2. Correcting Vision

Even minor vision issues can worsen symptoms. Your provider may recommend glasses or contact lenses, including specialized computer glasses with anti-glare lenses for screen use.

3. Adjusting Your Routine & Environment

Minor changes to your setup and habits can help reduce eye strain:

  • Take breaks: Follow the 20-20-20 rule—every 20 minutes, look at something 20 feet away for 20 seconds.
  • Limit screen time: Aim for less than four hours daily when possible.
  • Improve posture: Set up an ergonomic workstation to avoid neck and eye strain.
  • Reduce glare: Adjust lighting and screen brightness to match the room’s ambient light.
  • Enlarge text: Increase font size and use high-contrast settings for easier reading.

These simple adjustments can make a big difference in keeping your eyes comfortable using digital devices.

Frequently Asked Questions

Cutting back on screen time can help ease symptoms, but the discomfort may return or worsen if you use digital devices daily. If your job requires extended screen use, talk to an optometrist at Abasa Optical about long-term management strategies.

It’s recommended to have an eye exam once a year to monitor your eye health. However, you should see an eye care specialist sooner if:

  • You develop new symptoms of computer vision syndrome (CVS).
  • Your symptoms persist or worsen despite making adjustments.

Healthy screen habits, such as taking breaks, adjusting your workspace, and reducing glare, can help prevent computer vision syndrome (CVS).
