Contact Lenses, Pool Water And The Holiday Eye Trap

Most eye problems associated with travel do not begin with an exotic bug, a suspicious hotel pillowcase or a beach cocktail served in something shaped like a parrot. They usually start with a far more ordinary villain: people abandoning the sensible eye-care habits they follow perfectly well at home.

The Destination Is Rarely The Problem. The Behaviour Is.

Travel has a marvellous way of convincing otherwise reasonable adults that normal rules have been temporarily suspended. Breakfast becomes cake-adjacent. Sunscreen is applied with the strategic precision of a man painting a fence in a gale. Contact lenses, meanwhile, are treated as if they have suddenly developed supernatural powers.

According to Mr Mfazo Hove, ophthalmic surgeon and founder of Blue Fin Vision, the real risk is not that travel itself damages the eyes. It is that holidays encourage small lapses: lenses left in too long, dry eyes dismissed as tiredness, symptoms blamed on jet lag, and treatment postponed because nobody wants to spend a week in Marbella sitting under fluorescent clinic lighting.

That is the awkward truth about holiday eye health. Your eyes do not care that you have booked dinner, paid for a lounger, or finally found a hotel pool that does not resemble a municipal soup. If something is wrong, it remains wrong in every time zone.

Dry Eyes On Flights: The Mile-High Irritation

Aircraft cabins are famously unkind to the human body. They dry out skin, flatten hair, ruin sleep and turn perfectly decent eyes into two lightly toasted raisins.

Cabin humidity can be extremely low, and when that is mixed with alcohol, lack of sleep and several hours staring at a screen six inches from your nose, dry eyes during flights become all too predictable. The result is that gritty, scratchy, blinking-like-a-lizard feeling many travellers recognise before the seatbelt sign has even been switched off.

Lubricating eye drops before and during the flight can help. Contact lens wearers should be particularly careful on long journeys and, where possible, consider removing lenses before settling into a lengthy flight. It is not glamorous, admittedly. But neither is arriving with eyes that look as though they have spent the journey arguing with the air-conditioning.

The great contact lens commandments are clear enough at home. Do not sleep in them unless specifically advised. Do not swim in them. Do not over-wear them. Do not reuse them beyond their intended lifespan.

Then comes the holiday, and suddenly all of this is treated as optional, like reading the safety card or pretending to enjoy airport sushi.

Contact lenses on holiday are one of the most common weak points in travel eye health. People sleep in them on overnight flights, wear them for longer than recommended, swim in them, hot tub in them, or discover their replacements are packed somewhere deep in a suitcase beneath three pairs of unnecessary shoes.

These habits increase the risk of eye infection. Redness, pain, light sensitivity or blurred vision after sleeping or swimming in contact lenses should not be treated as a minor inconvenience. They should be assessed urgently.

The problem with eye infections is that they rarely improve because one has a nice view. A luxury resort does not sterilise poor contact lens hygiene. It simply makes the mistake more expensive-looking.

UV Exposure: Snow, Sand, Water And A False Sense Of Security

Many travellers underestimate reflected ultraviolet light. Sand, water and snow can all bounce UV back towards the eyes, which is why proper UV-rated sunglasses or goggles are not a decorative flourish but basic equipment.

Snow deserves particular attention. Skiers can develop photokeratitis, often called snow blindness, even on cloudy days. It is essentially sunburn of the front surface of the eye, which sounds unpleasant because it is.

Beach holidays bring their own version of the same issue. Sailing, swimming, sunbathing and walking along bright coastal paths all increase exposure. The lesson is simple: sunglasses should offer proper UV protection, not merely make the wearer look like a retired racing driver avoiding tax questions.

Pools, Hot Tubs And The Myth Of Clean Water

Chlorinated water is not sterile. This is one of those facts that feels inconvenient enough to be ignored, particularly when the pool is blue, the tiles are tasteful and someone has just brought over a small bowl of olives.

Swimming pools, hot tubs and recreational water sources can harbour microorganisms capable of causing eye infections. The risk is higher for contact lens wearers because lenses can trap organisms against the eye.

That does not mean travellers need to approach every swimming pool like a crime scene. It does mean contact lenses and water are a poor combination. Prescription goggles, daily disposables used correctly, or simply removing lenses before swimming are better options than hoping chlorine has handled everything like a tiny aquatic bouncer.

Floaters And Flashes Abroad: The Symptoms Not To Explain Away

This is where eye problems associated with travel move from irritating to potentially serious.

A sudden increase in floaters, flashes of light or the appearance of a shadow in the vision may indicate a retinal tear or retinal detachment. These symptoms can appear at home or abroad, but travel introduces a dangerous delay. People blame bright sunlight, dehydration, tiredness or jet lag. They wait. They negotiate with themselves. They decide it can be dealt with once they are back.

That delay can matter. A retinal tear may be treatable quickly with laser treatment. If it progresses to a retinal detachment, surgery may be needed.

The advice here is not complicated: if your vision changes suddenly while travelling, seek local medical advice the same day. Not after the excursion. Not after the buffet. Not once you have checked whether the hotel Wi-Fi is any better near reception.

Simple Travel Eye Health Rules Worth Packing

A sensible eye-care travel routine does not need to be complicated. Pack lubricating drops if you are prone to dry eyes. Carry spare contact lenses and your glasses in hand luggage. Do not swim, shower or sleep in lenses unless specifically advised that your lenses are suitable for overnight wear. Use properly UV-rated sunglasses or goggles. Treat pain, redness, light sensitivity, blurred vision, new floaters, flashes or a shadow in your vision as warning signs rather than holiday trivia.

Travel rarely harms the eyes directly. Trouble begins when normal precautions are abandoned and symptoms are waved away as an inconvenience. Your eyes require the same discipline in an airport lounge, ski resort, hotel pool or beach bar as they do at home.

The suitcase can contain all manner of questionable decisions. Your eye health should not be one of them.
