Contact Lens Safety Tips for Travelers: Maintaining Clean and Clear Vision on the Go
As an optometrist with years of experience, I often hear from patients excited about upcoming trips, but sometimes they don’t fully consider how travel impacts their contact lens wear. Maintaining proper contact lens hygiene is crucial always, but when you’re away from your usual routine, it requires extra vigilance. This isn't about scaring you – it's about equipping you with the knowledge to enjoy your travels with comfortable, clear vision.
What are the biggest risks for contact lens wearers while traveling?
The biggest risks stem from disruptions to your normal hygiene routine and increased exposure to potential irritants. Think about it: you might be using different water sources, facing more dust and allergens, or simply being tired and less meticulous. Here’s a breakdown:
- Water Quality: This is huge. Never, ever use tap water to rinse or store your contact lenses. Water sources vary drastically, and even what seems “clean” can contain microorganisms like Acanthamoeba, which can cause a serious, vision-threatening infection. This risk isn't limited to developing countries; even in North America, tap water isn’t sterile.
- Environmental Irritants: Dust, sand, smoke (from campfires or wildfires, a concern in Western Canada, including around Okotoks and Calgary), and even increased pollen counts can all irritate your eyes and increase the risk of infection.
- Reduced Access to Supplies: Running out of solution or a lens case while on the road is more common than you think. Forgetting a backup pair of glasses is another frequent issue.
- Air Travel: The dry cabin air in airplanes can significantly reduce tear production, leading to dry eyes and discomfort for contact lens wearers.
- Extended Wear Concerns: While extended-wear lenses are convenient, travel isn’t the time to push the limits. The potential for complications increases with longer wear times, especially when hygiene may be compromised.
How much contact lens solution and supplies should I pack?
It's always better to overpack than underpack. I recommend the following minimums for a two-week trip, even if you normally wear daily disposables:
- Daily Disposable Lenses: Pack enough for every day of the trip + 3-4 extra pairs. Delays happen, and having spares is essential.
- Non-Daily Disposable Lenses: Pack a spare set of lenses, even if you have a current prescription.
- Contact Lens Solution: Bring travel-sized bottles, but pack enough to last the entire trip + 50%. A 250ml bottle might seem sufficient for two weeks, but a little goes a long way when you are trying to be conservative.
- Lens Cases: Pack at least two new, clean lens cases. Cases themselves can harbor bacteria, and replacing them frequently is vital.
- Eye Drops (Artificial Tears): Essential for combating dry eyes, particularly during flights. Choose preservative-free drops if you use them frequently.
- Glasses: Absolutely crucial! Bring your most up-to-date prescription glasses as a backup, in case of irritation, infection, or lost/damaged lenses.
Consider packing these items in your carry-on luggage. If your checked luggage is delayed, you’ll still have the essentials.
What about water? Can I use bottled water for my lenses?
Bottled water isn’t necessarily sterile, but it's a much better option than tap water. However, the type of bottled water matters. Avoid distilled or purified water that hasn't been sterilized. Look for bottled water specifically labeled as “sterile” – this undergoes a purification process that removes microorganisms. Even then, many professionals recommend using a commercially prepared saline solution specifically designed for contact lenses. It’s a small investment for significant peace of mind.
I’m going to a remote location with limited access to healthcare. What precautions should I take?
This requires extra planning. I advise patients in this situation to consider switching to daily disposable lenses for the duration of the trip. This eliminates the need for lens cases and reduces the risk of contamination. Also:
- Bring a comprehensive eye care kit: Include everything listed above, plus antibiotic eye drops (with a prescription from your optometrist – you can't just buy these over the counter), and pain relief drops.
- Know the symptoms of a corneal infection: Redness, pain, blurred vision, sensitivity to light, and excessive tearing are all red flags.
- If you experience symptoms, remove your lenses immediately and seek medical attention:** Even if it means cutting your activity short. Delaying treatment can have serious consequences.
How can I minimize dry eye symptoms during air travel?
Air travel is notoriously drying for contact lens wearers. Here’s what can help:
- Hydrate: Drink plenty of water before, during, and after your flight.
- Use artificial tears: Apply eye drops liberally throughout the flight. Preservative-free options are best for frequent use.
- Blink frequently: Consciously blink to keep your eyes lubricated. We tend to blink less when concentrating on screens or reading.
- Consider wearing glasses during the flight: This gives your eyes a break from the lenses and reduces the risk of dryness.
- Adjust air vents: Direct the overhead air vent away from your face to minimize airflow directly into your eyes.
What should I do if I experience discomfort or irritation while wearing contacts on my trip?
Don’t ignore it! The first step is to remove your lenses. If the discomfort persists, or if you notice any signs of infection (redness, pain, blurred vision), consult a local healthcare professional immediately. Don’t try to “tough it out.” Early intervention is key.
What if I swim or participate in water sports while traveling?
This is a big one. Generally, I advise against wearing contact lenses while swimming or participating in water sports, even with goggles. The risk of introducing microorganisms into your eyes is simply too high. If you must wear them, consider daily disposables and discard them immediately after swimming. Goggles provide some protection, but aren’t foolproof.
How often should I have my eyes examined before a trip?
A comprehensive eye exam within 12 months of your travel is ideal. If you have a history of eye problems or wear specialty lenses, a more recent exam (within 6 months) is recommended. This ensures your prescription is up-to-date and that your eyes are healthy before you embark on your journey. We can also discuss any specific concerns you have about traveling with contact lenses and provide personalized recommendations.
Remember, taking a few extra precautions can make all the difference in ensuring a comfortable and enjoyable trip. Prioritize your eye health, and don’t hesitate to seek professional advice if you have any questions or concerns.
