The Importance of Removing Contact Lenses Before Boarding a Plane
Air travel is a marvel of modern technology, allowing us to traverse great distances in a matter of hours. However, flying comes with its own set of challenges and potential discomforts, particularly for those who wear contact lenses. Although it may seem like a minor detail, removing contact lenses before boarding a plane can significantly enhance your comfort and protect your eye health. This article delves into the reasons why it’s advisable to take out your lenses before flying and provides practical tips for maintaining eye health during air travel.
The Airplane Environment and Its Impact on Eye Health
Low Humidity Levels
One of the primary reasons to remove contact lenses before flying is the low humidity level in airplane cabins. The air inside an airplane is often drier than the Sahara Desert, with humidity levels typically ranging between 10-20%. This dry air can cause your eyes to lose moisture more rapidly, leading to dryness and irritation. For contact lens wearers, this can result in a feeling of grittiness or a burning sensation in the eyes, as the lenses can exacerbate the dryness.
Pressurized Cabin Atmosphere
Airplane cabins are pressurized to simulate conditions at approximately 6,000 to 8,000 feet above sea level. While this makes breathing easier and helps passengers avoid altitude sickness, it can also affect the eyes. The reduced pressure can lead to changes in the fit and comfort of contact lenses, causing them to become less effective and more uncomfortable.
Extended Wear and Reduced Blink Rate
During a flight, especially a long one, it’s common for passengers to fall asleep or engage in activities like reading or watching movies. These activities often lead to reduced blinking, which is crucial for maintaining eye moisture and health. Wearing contact lenses in such conditions can increase the risk of developing dry eye symptoms and even lead to more serious complications, such as corneal ulcers or infections.
Risks Associated with Wearing Contact Lenses on a Plane
Increased Risk of Infection
The dry, pressurized environment of an airplane can create ideal conditions for bacteria and other pathogens to thrive. Contact lenses can trap these microorganisms against the surface of your eye, increasing the risk of infection. In severe cases, this can lead to conditions like keratitis, an inflammation of the cornea that can cause pain, redness, and blurred vision.
Hypoxia and Corneal Swelling
Hypoxia occurs when the cornea does not receive enough oxygen. In a low-humidity, low-pressure environment, the risk of hypoxia increases, especially if you’re wearing contact lenses. This can lead to corneal swelling, which can cause discomfort and even long-term damage to your eyes if not addressed.
Discomfort and Visual Disturbances
Even if you avoid serious complications, wearing contact lenses on a plane can simply be uncomfortable. The combination of dry air, reduced blinking, and extended wear can cause lenses to become dry and less effective, leading to blurred vision and general discomfort. This can make your flight less pleasant and leave your eyes feeling sore and tired upon arrival.
Practical Tips for Contact Lens Wearers
Switch to Glasses
The simplest and most effective way to avoid these issues is to switch to glasses for the duration of your flight. Glasses do not interfere with your eye’s natural moisture balance and eliminate the risks associated with contact lens wear in a dry, pressurized environment.
Hydrate Your Eyes
If you must wear contact lenses, ensure you keep your eyes well-hydrated. Use lubricating eye drops approved for use with contact lenses to maintain moisture levels. However, be mindful of the type of drops you use; some may not be suitable for use with certain types of lenses.
Practice Good Hygiene
Maintaining good hygiene is crucial when handling contact lenses, especially in an environment prone to bacterial contamination. Ensure your hands are clean before touching your lenses and avoid touching your face or eyes unnecessarily.
Use High-Quality Lenses
If you prefer to keep your contacts in during a flight, opt for high-quality, breathable lenses designed for extended wear. These lenses allow more oxygen to reach your cornea, reducing the risk of hypoxia and associated complications.
Limit Lens Wear Time
Try to limit the amount of time you wear your contact lenses during the flight. For instance, you might wear glasses during takeoff and landing and only switch to lenses when necessary. This can help reduce the cumulative impact of the dry, pressurized environment on your eyes.
Stay Hydrated
Keeping your body hydrated can help maintain overall moisture levels, including in your eyes. Drink plenty of water before and during your flight, and avoid alcohol and caffeine, which can contribute to dehydration.
Consult with an Eye Care Professional
Before traveling, consult with your eye care professional to discuss your specific needs and any precautions you should take. They can provide personalized advice and recommend the best products to keep your eyes healthy during air travel.
Conclusion
While the convenience of contact lenses is undeniable, air travel presents unique challenges that can make wearing them uncomfortable and potentially harmful. The dry, pressurized cabin environment, combined with extended wear and reduced blinking, can lead to dryness, irritation, and increased risk of infection. By removing contact lenses before boarding a plane, you can help protect your eye health and ensure a more comfortable journey. Switching to glasses, staying hydrated, practicing good hygiene, and consulting with an eye care professional are all effective strategies to mitigate the risks associated with flying with contact lenses. Prioritizing your eye health will not only make your flight more enjoyable but also help prevent long-term complications
