Digital Eye Strain: Prevention and Management

Digital eye strain, clinically known as Computer Vision Syndrome (CVS), affects between 64% and 90% of office workers. Research from the American Academy of Optometry shows significant correlations between screen time and visual discomfort.

Scientific Evidence of Digital Eye Strain

Recent studies have identified several key factors contributing to eye strain:

• Reduced blink rate (from 15 to 5-7 blinks per minute)
• Increased exposure to blue light
• Extended near-point focusing
• Poor display ergonomics and ambient lighting

Evidence-Based Prevention Strategies

Research-backed methods to reduce digital eye strain include:

• The clinically-proven 20-20-20 rule
• Proper screen positioning (20-28 inches from eyes)
• Regular use of artificial tears
• Appropriate ambient lighting conditions
