Treatment
Computer Vision Syndrome: Managing Digital Eye Strain
Computer Vision Syndrome (CVS), also called digital eye strain, affects up to 90% of computer workers. It is a cluster of eye and vision problems caused by prolonged screen use. Symptoms typically improve with rest but recur with screen exposure if ergonomics and habits are not addressed.
Overview
Computer Vision Syndrome: Managing Digital Eye Strain
Uses & Indications
Eye strain, soreness, or fatigue during or after screen use
Dry, irritated eyes from reduced blinking
Blurred vision — temporary difficulty refocusing after screen work
Headaches, especially frontal or behind the eyes
Neck, shoulder, or back pain from poor posture
Double vision or difficulty tracking text on screen
How to Use
Reduced blink rate (from 15 to 5-6 times per minute on screens)
Poor workstation ergonomics — screen too bright, too close, at wrong angle
Uncorrected or undercorrected refractive errors (glasses wrong for screen distance)
Glare from overhead lighting or windows reflecting on screen
Low-contrast text or small font sizes requiring extra focusing effort
Air conditioning and heating creating dry environments
Benefits & Effectiveness
Follow the 20-20-20 rule: every 20 min, look 20 feet away for 20 seconds
Position screen 50-70 cm away, slightly below eye level
Use lubricating eye drops to combat dry eye from reduced blinking
Adjust screen brightness and contrast to match ambient light
Use computer glasses with blue-light filter and anti-reflective coating
Increase font size and use high-contrast themes
Regular eye exams to ensure glasses prescription is current for screen use
