Computer Vision Syndrome (CVS) Causes and Prevention

Computer Vision Syndrome (CVS) is a collection of eye and vision-related problems that occur while using digital devices, with prolonged screen viewing being a major contributing factor. This syndrome can include symptoms such as eye strain, dry eyes, headaches, blurred vision, double vision, eye swelling, and dry eyes, and it manifests as experiencing eye discomfort due to prolonged screen use.

Main Causes of CVS

(1) Prolonged Screen Use

Using digital devices such as computers, smartphones, and tablets for extended periods requires continuous eye work, which can lead to eye strain.

(2) Screen Light and Glare

Screens emit strong light and glare, which can irritate the eyes and cause fatigue.

(3) Fixation at a Fixed Distance

While viewing a screen, the eyes are fixed at a specific distance, which puts strain on the eyes and can worsen eyesight.

(4) Habit of Not Blinking

There is a tendency to blink less or not blink while looking at a screen, which can lead to dry eyes.

(5) Screen Addiction

Addictive use of digital devices can increase screen time and the risk of CVS.

(6) Impact on Sleep Patterns

The blue light from screens can interfere with the production of melatonin, a sleep hormone, and lead to sleep problems.

Several Ways to Prevent and Alleviate CVS Symptoms

(1) Maintain Proper Distance from the Screen

Maintain a proper distance (approximately 65 cm) between your eyes and the computer screen or monitor, and adjust the screen slightly above eye level.

(2) Follow the 20-20-20 Rule

Develop a habit of looking at something 20 feet away for 20 seconds every 20 minutes. This can reduce eye strain.

(3) Blinking

Make it a habit to blink consciously and frequently, providing adequate rest for your eyes.

(4) Eye Exercises and Habit Training

Regular eye exercises and habit training can strengthen the eye muscles and reduce eye fatigue.

(5) Appropriate Lighting and Display Settings

Adjust screen brightness and contrast, and use a high-resolution display to reduce eye strain.

(6) Regular Eye Exams

Get regular eye and vision checks to maintain eye health.

(7) Exercise and Stretching

Consistent exercise and body-moving stretches can relieve both body and eye fatigue.

(8) Sleep Pattern Management

Reduce screen time before sleep and limit blue light emission to manage your sleep patterns.

Computer vision syndrome is a common problem in modern life, and it is important to protect your eye health through prevention and proper habits.
