Can you take contact lenses on a plane?
Why your eyes feel drier in the air
Once the plane takes off, the environment for your eyes changes. Cabin humidity is often as low as 20% compared to the 40–60% you’d usually experience on the ground. This dry air makes tears evaporate faster, which can lead to:
Quicker dehydration of the tear film
Irritated, stinging or tired eyes
Increased eye strain, especially when reading or looking at a screen
If you wear soft contact lenses, you might notice dryness more quickly as they retain moisture but can also dry out faster in low humidity.
The best contact lenses for flying
Daily disposable contact lenses
For many travellers, daily disposable contact lenses are the most convenient and hygienic choice. Pop in a fresh pair in the morning, wear them during your journey, then simply throw them away at the end of the day. There’s no need for a contact lens case or contact lens solution in your carry-on bag.
Monthly or two-weekly lenses
Prefer your usual lenses when you fly? No problem; just be prepared. Always pack a travel-sized bottle of contact lens solution (100ml or less) in your hand luggage, such as everclear REFRESH, to keep lenses fresh and comfortable, even mid-flight.
Extended wear lenses
While extended wear contact lenses might sound convenient to keep these lenses in for the entire journey, eye care professionals generally advise removing contact lenses before sleeping on a flight. In-flight sleeping combined with dry air can limit the oxygen reaching your cornea, increasing the risk of dryness and discomfort.
How to prevent dryness and discomfort in-flight
Stay hydrated: Drink plenty of water and limit caffeine or alcohol, which can dehydrate you.
Use rewetting drops: Keep a small, preservative-free bottle like Systane Ultra Preservative Free in your carry-on.
Blink often: Especially if you’re reading or using a digital device.
Wear glasses for long-haul flights: Switch to a pair of glasses and insert a fresh pair of contact lenses before landing.
Avoid rubbing your eyes: This can cause irritation or dislodge your lenses.

FAQs about flying with contact lenses
Can I wear contact lenses on a long-haul flight?
Yes, but remove them before sleeping and keep your eyes hydrated with rewetting drops.

What are the best lenses for flying?
Daily disposable contact lenses are the most hygienic and convenient choice for air travel.
And don’t forget...
The dry, recirculated air in a plane can increase the risk of eye infections. Always wash your hands thoroughly with soap and water before handling your lenses. If that’s not possible, use a hand sanitiser with at least 60% alcohol and wait until your hands are completely dry before touching your eyes.
The takeaway for takeoff
Flying with contact lenses can be comfortable and safe with the right preparation. Opt for daily disposables for shorter trips, keep your eyes hydrated with eye drops, pack a travel-sized bottle of solution for longer journeys, and switch to glasses mid-flight if needed. By following these travel tips, you’ll arrive with fresh eyes ready to enjoy your destination.
