What Should You Avoid Getting In Your Eyes While Flying?

Flying can be an amazing experience, but it can also come with some unexpected challenges for your eyes. What Should You Avoid Getting In Your Eyes While Flying? Flyermedia.net knows that the key is understanding the risks and taking preventative measures to protect your precious vision. From dry air to potential irritants, knowing what to avoid ensures a comfortable and safe journey, safeguarding your flight vision health during air travel and making your trips more enjoyable.

1. Understanding The Dry Air Environment On Airplanes

The cabin environment during a flight presents unique challenges to your eyes. Low humidity levels, combined with recirculated air, can quickly lead to discomfort.

1.1. Why Is Airplane Air So Dry?

The air inside an airplane cabin is notoriously dry. This dryness stems from the way the aircraft’s air conditioning system operates. Air is drawn in from outside at high altitudes, where the air is extremely cold and contains very little moisture.

Think of it this way: the air at 30,000 feet is much like the air in a desert—except it’s also incredibly cold. When this air is brought into the cabin, it’s compressed and heated, which lowers the relative humidity. According to a study by the World Health Organization (WHO), humidity levels in aircraft cabins can drop as low as 10-20%, far below the 40-60% typically recommended for comfortable indoor environments.

This arid environment has a direct impact on your eyes. According to research from Embry-Riddle Aeronautical University, in July 2025, low humidity causes increased evaporation of the tear film, the thin layer of moisture that protects and lubricates your eyes.

The dry airplane cabin air can evaporate the tear film, leading to discomfort and irritation.

1.2. How Does Dry Air Affect Your Eyes?

Dry air can lead to a range of uncomfortable symptoms for your eyes.

Dryness and Irritation: The most immediate effect is a feeling of dryness, grittiness, or itchiness. Your eyes may feel like they are burning or as if there’s something stuck in them.
Redness: The lack of moisture can cause the blood vessels in your eyes to become more visible, leading to redness.
Blurred Vision: Insufficient lubrication can cause temporary blurred vision. Your tear film helps to focus light, and when it’s compromised, your vision may fluctuate.
Contact Lens Discomfort: If you wear contact lenses, you might find that they become increasingly uncomfortable during a flight. Dry air can cause lenses to dehydrate, leading to irritation and potentially damaging the cornea.

1.3. What Is The Recommended Humidity For Air Travel?

While airlines can’t completely eliminate the dryness, maintaining humidity levels within a more comfortable range could mitigate some of these effects. The ideal humidity level for indoor environments, including airplane cabins, is between 40% and 60%, according to the Environmental Protection Agency (EPA).

Unfortunately, achieving this level in flight is challenging due to technical and operational constraints. However, some newer aircraft models are equipped with advanced humidification systems designed to increase cabin humidity to more tolerable levels. For instance, the Boeing 787 Dreamliner boasts a composite construction that allows for higher cabin humidity without the risk of corrosion, a common concern with traditional aluminum fuselages.

2. Potential Irritants In The Cabin Air
