Short answer: yes, you can take contact lenses in your hand luggage to the Canary Islands. Sealed blister packs of daily lenses are packaged items rather than liquids, while lens solution counts towards your liquids allowance. Pack more lenses than you think you need, keep glasses and rewetting drops in your cabin bag, and keep your lenses out of the sea and the pool.
The islands then add a few challenges of their own: dry cabin air on a four-hour flight, trade winds that carry sand, the occasional calima and UV levels that reach 11 in summer. This guide takes each one in turn, from the security tray at your UK airport to the upper slopes of Teide.

Can you take contact lenses in hand luggage?
Contact lenses are allowed in hand luggage on every flight between the UK and the Canaries. The only real question is which parts of your kit count as liquids.
Daily disposables come in small foil-sealed blister packs, and airport security treats these as packaged items, so they do not normally need to go in your liquids bag. If an officer asks you to put them in anyway, a strip of blisters takes up very little room.
Lens solution is different. GOV.UK lists contact lens solution as a liquid, so it follows the same rules as your toothpaste and sun cream. At most UK airports that still means containers of 100ml or less in a single clear bag of up to one litre. Airports with the newer security scanners, including Heathrow, Gatwick, Edinburgh and Birmingham, now accept containers of up to 2 litres, while Manchester, Stansted and Luton still applied the 100ml rule at the time of writing. The rollout is ongoing, so check your departure airport’s security page in the week you fly.
The return leg matters just as much. Spanish airports, including those on the islands, still work to a 100ml limit per container, so a large bottle that went through Heathrow without a second look can be taken off you at Tenerife South Airport on the way home. Pack for the strictest airport on your route: a travel-size bottle of solution in your cabin bag and the full bottle in the hold.
| Item | Hand luggage | Hold luggage |
|---|---|---|
| Daily lens blister packs | Enough for the first few days, plus spares | The rest of your supply |
| Lens solution (monthly or fortnightly lenses) | Travel size, 100ml or less | Full-size bottle |
| Lens case | Yes | A spare case |
| Glasses | Yes, always | No |
| Rewetting drops | Small bottle, counts as a liquid | Optional spare |
| Sunglasses | Yes | No |
| Your prescription details | Photo on your phone | Paper copy |
How many contact lenses to pack for a week or a fortnight
Take one pair for every day of your holiday, then add at least a third again. A week away means around ten pairs; a fortnight means around 20.
The extra lenses are not padding. On a beach holiday you get through more lenses than at home: a pair goes in the bin after any swim where water reaches your eyes, sand can force an early change, and a lens dropped on a hotel bathroom floor is a lost lens. Flight delays happen too, and replacing your exact prescription on the islands is less straightforward than reordering at home. Split your supply between your cabin bag and your hold bag, so a delayed suitcase does not leave you without lenses.
Daily disposables suit this kind of trip because there is nothing to clean: no solution to carry through security, no case to rinse, and a fresh pair is always one blister away when sand or salt water gets involved. If you wear monthlies at home, ask your optician a few weeks before you travel whether a daily lens would work for you, as a new lens type needs a proper fitting. Well-known ranges such as DAILIES contact lenses come in boxes of 30 lenses, so one box per eye covers a fortnight with plenty to spare.
Wearing contact lenses on the flight
A flight to the Canaries takes around four to four and a half hours from London and a little longer from Scotland and Northern Ireland, as our guide to the flight time from the UK to Tenerife shows. That is long enough for the cabin air to make itself felt. Studies on commercial flights have measured relative humidity at roughly 9 to 28 per cent, and dry air dries out lenses and eyes alike.
A few habits make the difference:
- Use rewetting drops that are suitable for contact lenses, and pack the bottle with your other liquids.
- Turn the overhead air vent away from your face.
- Take your lenses out before you sleep on the plane and switch to glasses.
- If you wear dailies, put a fresh pair in after landing rather than nursing a dry pair through transfer day.
Can you wear contact lenses in the sea or the pool?
Optometrists’ advice is to avoid it. The Association of Optometrists warns that contact lens wearers face a much higher risk of eye infections from swimming. The organisms of most concern are bacteria such as Pseudomonas and an amoeba called Acanthamoeba, which can cause severe pain and, in serious cases, sight loss. A lens can trap these organisms against the eye, and a well-chlorinated pool is no guarantee, because chlorine does not kill Acanthamoeba cysts.
If you do get in the water with lenses in, follow the advice the Association of Optometrists passes on from the British Contact Lens Association: wear daily disposables under well-sealed goggles or a mask, and throw the lenses away as soon as you are out. Never rinse lenses or a lens case in tap water. For regular swimmers and snorkellers, prescription goggles or a prescription dive mask are the better long-term answer.
This matters more in the Canaries than on many holidays, because so much of the swimming happens in the Atlantic rather than in calm hotel pools. The islands’ natural rock pools, known locally as charcos or piscinas naturales, refill with every swell, and waves often break straight over the rocks. Favourites include the lava pools of El Caletón in Garachico on Tenerife, the Las Salinas pools in Agaete on Gran Canaria and Charco Azul on El Hierro. Expect a faceful of seawater at any of them, and treat a dip in a rock pool exactly as you would a swim in the open sea.
Wind, sand and calima
The trade winds that keep the islands’ temperatures comfortable also carry sand, and a single grain under a lens is enough to end your afternoon on the beach. Fuerteventura and Lanzarote are known for strong, steady winds: the long beaches at Sotavento and Famara draw windsurfers and kitesurfers for good reason. On Gran Canaria, the Maspalomas dunes can send fine sand across the beach on a breezy afternoon.
Wraparound sunglasses do most of the work here. If sand does get in, resist the urge to rub, which can scratch the surface of the eye. Wash and dry your hands, take the lens out and put in a fresh one rather than trying to rinse it.
Calima is the other local factor. These episodes of hot, dust-laden air from the Sahara turn the sky hazy and the air very dry, and the Canarian broadcaster RTVC has reported that calima makes dry eyes worse. On heavy calima days, wear your glasses for at least part of the day, use your rewetting drops more often and cut your wearing time. Our Corralejo weather guide explains how the trade winds and calima behave through the year.
Sun and altitude: UV on the beach and on Teide
The Canaries lie far to the south of the UK, and the UV index shows it. Monthly figures for Santa Cruz de Tenerife put the peak UV index at 4 in December and January, 7 in October and 11, rated extreme, from June to August. From March to October it sits at 7 or above. Our Tenerife weather guide covers the month-by-month picture.
Contact lenses are not a substitute for sunglasses. Even lenses with a UV filter cover only the cornea, leaving the rest of the eye and the eyelids exposed, so pack sunglasses marked UV400 or carrying the CE or UKCA mark, ideally a wraparound pair that also keeps out the wind.
Altitude raises the stakes. The World Health Organization notes that UV intensity rises by nearly 10 per cent for every 1,000 metres you climb. The Teide cable car takes you to around 3,550 metres, so UV up there is roughly a third stronger than on the beach, and the air is cooler, drier and often windy. If you are heading up to Teide National Park, take sunglasses, drops and your glasses as a backup, and do not let the cooler air fool you into thinking the sun is weaker.
Lost a lens or run out on holiday?
Ópticas, the Spanish name for opticians, are easy to find in the main resort towns and shopping centres on the larger islands, but they will need your exact details. Before you leave home, take a photo of a lens box or blister showing the brand, the power (often marked PWR or SPH), the base curve (BC) and the diameter (DIA), plus the cylinder and axis if you wear toric lenses for astigmatism. A copy of your prescription speeds things up.
If an eye becomes red, painful, watery or sensitive to light, take the lens out and leave it out. Pain after swimming in lenses needs same-day attention from a doctor or a hospital emergency department. UK residents should travel with a GHIC or a valid EHIC, which covers medically necessary state healthcare in Spain, alongside their travel insurance.
Contact lenses on holiday: FAQs
Do contact lenses count as liquids on a plane?
Sealed blister packs of daily lenses are not treated as liquids, so they can travel loose in your hand luggage. Contact lens solution does count as a liquid and must follow your airport’s limit, which is 100ml per container at most UK airports and at Spanish airports.
Can you wear contact lenses on the plane?
Yes. Lenses are fine to wear in flight, but cabin air is very dry, so use rewetting drops, take your lenses out if you want to sleep and keep your glasses in your cabin bag.
What is the 3:1:1 rule for contact lenses?
It is the US Transportation Security Administration’s liquids rule: containers of 3.4oz (100ml) or less, in one quart-size bag, one bag per passenger. UK and Spanish airports use their own version based on 100ml containers in a bag of up to one litre, and some UK airports now allow containers of up to 2 litres.
Can you swim in the sea with contact lenses?
Optometrists advise against it because of the risk of eye infections, including Acanthamoeba keratitis. If you do swim with lenses in, wear daily disposables under well-sealed goggles or a mask and throw them away as soon as you are out of the water.
Should I take glasses as well as contact lenses on holiday?
Yes. Glasses are your backup for a lost lens, an irritated eye, a long flight or a calima day, and they belong in your hand luggage.
