Computer Vision Syndrome, also known as Digital Eye Strain, is a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader, and smartphone use.
It affects millions of people who spend significant time in front of digital screens.
Computer Vision Syndrome may exhibit a range of symptoms, including: Eye Discomfort: Burning, stinging, or itching sensations in the eyes Visual Disturbances: Blurred or double vision, difficulty focusing
Physical Strain: Headaches, particularly around the forehead and temples
Neck and Shoulder Pain: Associated with poor posture during screen use
Dry Eyes: Reduced blinking leads to decreased tear production and eye lubrication.
Eye Fatigue: Feeling of heaviness or tiredness in the eyes after prolonged screen time.
Causes of Computer Vision Syndrome:
Harsh lighting and screen reflections increase eye strain.
Incorrect distance or angle between eyes and screen
Screen Brightness and Contrast: Improperly adjusted display settings
Existing vision issues can be exacerbated by screen use
People blink less frequently when using digital devices, leading to dry eyes
Poor ergonomics occurs from Incorrect seating position and screen placement
Prevention and Management Strategies include:
Ergononic adjustments by positioning screen about an arm’s length away, slightly below eye level.
Using an adjustable chair with proper back support
Ensure proper lighting to reduce glare
Every 20 minutes: Look at an object 20 feet away for 20 seconds, reducing eye strain and allows eye muscles to relax.
Adjust screen brightness and contrast for comfort
Use night mode or blue light filters
Increase text size for easier reading
Clean the screen regularly to reduce glare.
CVS is typically temporary.
Chronic and untreated symptoms, however can potentially lead to: Increased risk of myopia progression Chronic eye strain Long-term visual discomfort Reduced productivity
