Most people blink around twelve to twenty times per minute, but this rate often drops dramatically during screen use.
Why blinking matters
Each blink spreads fresh tears across the eye surface. Fewer blinks mean more evaporation, leading to dryness, grittiness, and blurred vision.
- Screen concentration can cut blink rate by half or more
- Incomplete blinks leave the lower cornea especially exposed
- Dry spots can cause fluctuating vision and eye fatigue
- Contact lens wearers are particularly affected
Healthy blinking habits
Conscious blinking helps keep eyes comfortable during long tasks. Simple reminders and exercises can gradually restore a more natural pattern.
- Every twenty minutes, do a set of slow, full blinks
- Position screens slightly below eye level to encourage natural blinking
- Use lubricating drops if dryness persists despite good habits
- Consider adjusting font size and contrast to reduce strain
