What is Digital Eye Strain (Computer Vision Syndrome)?

Digital Eye Strain is a collection of vision-related problems caused by extended use of digital devices like computers, smartphones, tablets, and gaming consoles. Unlike traditional eye fatigue, DES combines visual, muscular, and neurological strain.

Remember: Digital Eye Strain doesn’t cause permanent blindness, but if left unmanaged, it can worsen existing vision conditions like myopia, astigmatism, and presbyopia.

Causes of Digital Eye Strain

1. Blue Light Exposure

Screens emit high-energy blue light that contributes to fatigue, sleep disruption, and long-term retinal stress.

2. Reduced Blinking

While focused on screens, blinking rate drops by up to 60%, leading to dryness and irritation.

3. Poor Ergonomics

Wrong screen distance, poor posture, and bad lighting cause strain in the eyes, neck, and shoulders.

4. Extended Screen Time

Working or gaming for hours without breaks puts excessive stress on eye muscles.

5. Uncorrected Vision Issues

Mild astigmatism or presbyopia can significantly increase Digital Eye Strain symptoms.
