Computer Vision Syndrome: Causes, Symptoms, and Prevention Tips

Computer vision syndrome, also known as digital eye strain, is an increasingly prevalent condition resulting from extended use of computers, smartphones, and other digital devices. With modern society’s reliance on technology for work and leisure, many individuals experience symptoms of computer vision syndrome, impacting their comfort and ability to concentrate.

Computer vision syndrome typically arises from prolonged exposure to digital screens, which emit high-energy visible (HEV) blue light and require our eyes to focus and refocus continually, often at close range. As a result, the muscles in our eyes can become fatigued and strained, leading to a variety of uncomfortable symptoms. 

At Valley Laser Eye Centre, we understand the importance of maintaining healthy vision while utilizing digital devices in our daily lives. In this blog post, we will discuss the essential aspects of computer vision syndrome, its causes and symptoms, and practical prevention tips from our eye care specialists.

Causes of Computer Vision Syndrome

In today’s technology-driven world, many factors contribute to the development of computer vision syndrome, including:

1. Prolonged screen time: Spending excessive amounts of time in front of digital screens, such as computer monitors, tablets, and smartphones, can put a strain on our eyes and contribute to digital eye strain.

2. Poor ergonomics: Sitting in an improper position during screen usage or using a screen at an incorrect height or angle can place undue strain on the eyes, leading to discomfort and computer vision syndrome symptoms.

3. Lighting conditions: Glare from screens, insufficient lighting, or an overabundance of bright light in the environment can contribute to eye strain and discomfort associated with computer vision syndrome.

4. Pre-existing ocular conditions: Individuals with uncorrected refractive errors (nearsightedness, farsightedness, or astigmatism) or other eye conditions may be more susceptible to computer vision syndrome.

Symptoms of Computer Vision Syndrome

Common symptoms associated with computer vision syndrome include:

1. Eye discomfort: Straining, burning, or itchy eyes can result from prolonged screen usage.

2. Eye fatigue: Feeling of tiredness or heaviness in the eyes after extended periods of screen time.

3. Dry eyes: Digital screens can reduce the blink rate, leading to dry eyes and irritation.

4. Blurred vision: Prolonged focusing on digital screens can cause temporary blurred vision.

5. Headaches: Eye strain can lead to tension headaches, often experienced as dull, aching pain around the eyes or forehead.

6. Neck, shoulder, and back pain: Poor ergonomics while using digital screens can contribute to pain in the neck, shoulders, and back.

Prevention Tips from Valley Laser Eye Centre

At Valley Laser Eye Centre, we understand that maintaining good eye health is crucial in today’s digital age. To reduce the likelihood of developing computer vision syndrome and alleviate symptoms, consider implementing the following prevention tips:

1. Practice proper ergonomics: Ensure your workspace is set up ergonomically, with your screen positioned at eye level and approximately an arm’s length away. Adjust your chair to support a comfortable and upright posture, with your feet resting flat on the floor.

2. Employ the 20-20-20 rule: To minimize eye strain, follow the 20-20-20 rule by taking a 20-second break every 20 minutes to look at something at least 20 feet away.

3. Optimize screen settings: Adjust your screen settings to improve eye comfort. Consider reducing brightness, increasing text size, and using an anti-blue light filter or software to minimize blue light exposure.

4. Use proper lighting: Minimize glare by adjusting your screen angle, using blinds or curtains to reduce excessive sunlight, and using a desk lamp to provide adequate task lighting.

5. Blink frequently: Remember to blink regularly to maintain eye moisture and reduce the risk of dryness.

6. Adjust screen time habits: Limit recreational screen time, especially before bedtime, to reduce the overall daily exposure to digital screens and promote better sleep quality.

7. Get regular eye exams: Ensuring that your vision prescription is up-to-date and discussing any eye strain issues with your eye care professional can help reduce the impact of computer vision syndrome.
