Reduced Blinking Causes Dry Eyes
- Screen use reduces blinking from 15 to 5-7 times per minute, causing rapid eye dryness.
- Air blowing on your face speeds moisture evaporation, worsening eye strain symptoms.
Choose Purpose-Built Glasses
- Use two pairs of glasses: one for distance, another optimized for computer or reading.
- Avoid bifocals or progressives that restrict viewing zones and encourage rigid posture.
Practice Regular Screen Breaks
- Follow the 20-20-20 rule: every 20 minutes, look 20 feet away for 20 seconds.
- Take five-minute breaks each hour to stand, stretch, and let blinking recover.
