Why Your Eyes Dry Out on Long-Haul Flights (Fix)
The Science Behind Dry Eyes During Air Travel
Long-haul flights are notorious for causing discomfort, and dry eyes are among the most common complaints. At cruising altitude, airplane cabin humidity drops to 10-20%—drier than most deserts. This arid environment accelerates tear evaporation, leaving eyes feeling gritty and irritated. The problem intensifies because:
- Reduced Blink Rate: Passengers blink 60% less frequently when watching screens or reading
- Recirculated Air: Airplane ventilation systems prioritize temperature control over moisture retention
- Dehydration Factors: Altitude-triggered fluid loss affects tear production
6 Proven Solutions for In-Flight Eye Comfort
1. Artificial Tears: Your First Line of Defense
- Use preservative-free lubricating drops every 2-3 hours
- Avoid redness-reducing formulas containing vasoconstrictors
- Pro Tip: Store drops in your seatback pocket for easy access
2. Create a Personal Humidity Bubble
- Wear moisture-retaining goggles like Hybrid Sleep Masks
- Place a damp cloth over closed eyes during naps
- Position air vents away from your face
3. Smart Contact Lens Strategies
Lens Type | Recommendation |
---|---|
Soft Daily | Remove after 8 hours |
