Contact Lens Care for Travelers: Tips for Hygienic Lens Wear on the Go
As an optometrist with years of experience, I've heard countless stories – and seen a few unfortunate cases – related to contact lens hygiene, especially from travellers. People often think a vacation means loosening standards, but maintaining diligent lens care while travelling is more important, not less. Why? Because you're introducing new variables: different water sources, varying hygiene levels, and potentially limited access to your usual routine. This post will provide a detailed guide to keeping your eyes healthy and comfortable while enjoying your travels, whether you're exploring the Rockies near Okotoks, Alberta, or venturing further afield.
What are the biggest risks for contact lens wearers while traveling?
It's not just about forgetting solution. The biggest risks stem from water exposure and compromised hygiene. Here’s a breakdown:
- Acanthamoeba Keratitis: This is a rare but serious corneal infection linked to water exposure. Even microscopic amounts of water getting under your lenses can introduce the amoeba, leading to excruciating pain and potentially vision loss. This is the biggest concern for travellers. Think: showering with lenses in, swimming, hot tubs, even using tap water to rinse your case.
- Microbial Keratitis: Bacteria, fungi, and other microbes thrive in less-than-ideal conditions. Travel often means using shared facilities (like gym showers at hotels) or being exposed to different environmental bacteria.
- Dry Eye Syndrome: Airplanes, dry climates, and even changes in humidity can exacerbate dry eye, making lens wear uncomfortable and increasing the risk of irritation.
- Lost or Damaged Supplies: Luggage gets lost, bottles leak. Being unprepared can force you to wear lenses for extended periods or resort to unhygienic practices.
Most people don’t realize just how fragile the corneal surface is, and how quickly an infection can escalate. Prevention is truly key.
What should I pack in my contact lens travel kit?
Don’t just throw a bottle of solution in your bag! Be thorough. Here's a comprehensive checklist:
- Sufficient Solution: Bring more than you think you'll need. A good rule of thumb is to pack enough for at least twice the duration of your trip. Leaks happen, delays occur. A small bottle (around 60-90ml, travel-sized) is convenient for carry-on, but bring a larger bottle for checked baggage.
- Lens Case: Pack at least two. If one gets damaged, you have a backup. Consider a case with a mirror – useful in public restrooms.
- Daily Disposable Lenses (Recommended): If possible, switch to daily disposables for your trip. They eliminate the need for solution and significantly reduce the risk of infection. While they can be more expensive upfront, the peace of mind is worth it for many.
- Eyeglasses: Absolutely essential. Pack a current prescription copy in case of loss or damage. You need a reliable alternative if your lenses become uncomfortable or you experience an issue.
- Artificial Tears: Even if you don't normally use them, artificial tears can provide relief from dry eye during travel. Choose preservative-free options if you use them frequently.
- Hand Sanitizer: Critical for cleaning your hands before handling lenses, especially when you don’t have access to soap and water.
- Small Travel-Sized Disinfectant Wipes: For cleaning your lens case after each use.
- Emergency Lens Case & Solution (Smallest Size): A tiny backup lens case and a couple of solution ampules can be a lifesaver if your main supply is lost.
How do I maintain hygiene while on the go?
This is where things get specific. Here’s a breakdown of scenarios:
- Showering/Swimming: Never wear your contact lenses in the shower, hot tub, swimming pool, lake, or ocean. Period. The risk of Acanthamoeba Keratitis is simply too high. Always remove lenses before any water activity.
- Tap Water: Avoid using tap water to rinse your lens case or lenses, even in developed countries. The mineral content and potential microorganisms vary. Use only sterile saline solution or multipurpose solution.
- Handwashing: Wash your hands thoroughly with soap and water for at least 20 seconds before handling lenses. If soap and water aren't available, use hand sanitizer.
- Lens Case Care: After each use, empty the lens case, rinse it with sterile solution (not tap water!), and allow it to air dry open. Replace your lens case every 1-3 months, or sooner if it becomes damaged.
- Airplane Travel: The dry cabin air can quickly dehydrate your lenses. Use artificial tears liberally throughout the flight. Consider wearing your glasses during long flights to give your eyes a break.
- Accommodation Hygiene: If you’re staying in budget accommodations, be extra cautious about hygiene. Wipe down surfaces in the bathroom before handling lenses.
What about daily vs. extended-wear lenses?
Daily disposable lenses are by far the most hygienic option for travel. The convenience and reduced risk are significant. However, if you wear extended-wear lenses:
- Strictly adhere to the recommended wearing schedule: Do not exceed the maximum recommended wear time.
- Bring extra lenses: In case of damage or discomfort.
- Be extra vigilant about hygiene: Extended-wear lenses require even more meticulous care.
For some, switching to daily disposables for the duration of a trip is the most practical solution, even if they normally wear extended-wear lenses. It offers a significant safety margin.
What should I do if I experience eye irritation or discomfort while traveling?
Don't ignore it! Early intervention is crucial. If you experience redness, pain, blurred vision, or excessive tearing:
- Remove your lenses immediately.
- Switch to your eyeglasses.
- Use artificial tears for lubrication.
- If symptoms persist or worsen, seek medical attention immediately. Look for an optometrist or ophthalmologist in the area. Don’t wait until you return home.
Knowing where the nearest eye care professional is located at your destination (or having a telehealth option) can be incredibly helpful. In an emergency, delaying treatment can have serious consequences.
Traveling with contact lenses requires a little extra planning and diligence, but the reward – comfortable vision and a worry-free trip – is well worth the effort. Remember, prioritizing your eye health is essential, no matter where your adventures take you. A little preparation can go a long way in ensuring a safe and enjoyable experience.
