Travelling with glasses: why they arrive bent, and the fix
Your glasses made it through the flight, and then they got sat on in the taxi. It happens more often than anyone admits.

The safest way of travelling with glasses is a rigid clamshell case, placed in the middle of your cabin bag and padded by soft clothes. Carry a backup pair and a photo of your prescription in a separate bag. Most damage comes from pressure and drops, not from the journey itself.
What is the safest way to carry glasses in a bag?
Use a rigid, clamshell case and put it in the middle of your cabin bag, wrapped in soft clothing, never in an outer pocket or the hold. A soft pouch only prevents scratches. It does nothing against pressure, and pressure is what bends frames and pops lenses out of their grooves. Fold the temples correctly, right arm first and then the left, so the hinges do not fight each other. Keep the case away from the bag's seams and from anything heavy, such as a laptop charger or a shoe. A surprising amount of damage happens in the first ten minutes at the destination, when glasses are dropped on hotel tiles or left on a bed and sat on later. Give them one fixed home, such as the case on the bedside table, and return them there every single time. That habit prevents more breakages than any piece of kit.
Which glasses case is best for travel?
A hard-shell case, for almost every frame. It is the only kind that stands up to a squeezed bag. A soft pouch is fine against scratches in a pocket, and a folding case is a fair compromise for sunglasses you carry every day, but for a flight we would take the hard shell and keep the pouch for the walk to the beach. Look for one with a slightly raised inside, so the lenses never touch the lid. Shake the closed case: if the glasses rattle, it is too big. You want a snug fit that does not pinch the temples.
| Case type | Crush protection | Best for |
|---|---|---|
| Rigid clamshell | High | Flights, long trips, rimless frames |
| Semi-rigid zip case | Medium | Sunglasses, a spare pair in a second bag |
| Folding case | Medium | Day trips, sunglasses |
| Soft pouch | Low (scratches only) | An extra layer inside a hard case |
Keep the pouch anyway. Glasses in the pouch, pouch in the hard case, and you are covered against scratches and pressure. Put your microfibre cloth on top of the glasses inside the case, not underneath: a cloth under the frame lifts it and pushes the lenses against the lid.
How do you pack different frame materials?
Every frame wants a hard case, but each material fails in its own way.
- Acetate: sturdy, but it can warp in heat. Keep it off sunny windowsills, and check that thick temples let the case lid close flat.
- Metal and titanium: the nose pad arms bend first. Sit the glasses so the pads are not pressed against the case wall.
- Rimless: the most delicate, because the lenses hang on drilled mounts. Hard case only, nothing touching the lens edges, never loose in a bag pocket.
- Flexible or memory-metal frames: more forgiving in a squashed bag, but the lenses still scratch and crack like any others.
- Sports glasses and snow goggles: bulky, so give them their own pocket, or wear the goggles round your neck on the way to the slopes.

Should you take a spare pair when travelling?
Yes, and make it a current prescription, not an old pair from three years ago that gives you a headache by day two. A lost or broken pair abroad means blurred signs, a wasted first day and a hunt for an optician in an unfamiliar town. Pack the spare in a different bag from your main pair, so one lost suitcase or one dropped rucksack does not take out both. Online, a second pair of single vision glasses is affordable enough to treat as travel insurance. Frames under €30 for a car, travel or spare pair are gathered in our backup pair glasses under €30 collection. Also save a photo of your written prescription on your phone, plus a paper copy in your wallet, including the pupillary distance (PD) if it is listed. If yours is missing from the paperwork, ask your optician to add it.
- Spare pair in a second bag, in its own case
- Prescription photo saved offline on your phone, and a paper copy
- Your own microfibre cloth, because hotel towels and tissues scratch coatings
- A small screwdriver kit for loose hinge screws, kept in the hold
What should you do with your glasses at the airport and on the plane?
Keep them in your hand luggage, never the hold: you need them to read boarding passes and find your gate, and a delayed suitcase with your only pair inside means arriving somewhere new half-blind. Security rules differ between airports. Some let you keep your glasses on through the scanner, others ask you to take them off, so follow the staff. If they come off, case first, then tray.
Keep them on or in their case until the last moment, and never leave them loose in a security tray, where they slide off or get buried under a jacket. Security scanners do not damage lenses or coatings, so there is no need to worry about the machine itself. The real risks are the tray, the seat pocket and the tray table. Seat pockets are where glasses get forgotten, so use an inside jacket pocket or the case in your lap instead. If you sleep on a long flight, take them off and put them straight into the case, because a bent temple from a head pressed against a window is a classic. On arrival in a humid climate, expect fogging for a minute or two as the lenses adjust to the warmer air. Wipe them with a clean microfibre cloth rather than your shirt. If your eyes feel dry or uncomfortable after a long flight, ask your optician.
One rule people forget: before you stand up at the end of the flight, check the seat pocket, the tray table and your lap. More pairs get left behind in the rush to get off than get broken in the air.
How do you protect glasses from sand, heat and humidity?
Rinse sand and salt off with lukewarm water before wiping, because dry-wiping grit across a lens is how scratches start. Never leave glasses on a car dashboard or in a sun-baked glovebox. Heat can make the anti-reflective coating craze, which shows up as a fine web of cracks across the lens that cannot be repaired. Keep them in the case, in the shade, even for a quick swim. A few small habits help on the road:
- Pack a spare microfibre cloth and a small bottle of lens spray (within the cabin liquid limit)
- Rinse, then wipe, never the other way round
- Do not hang glasses from a shirt collar when leaning over a railing or a train window
- Dry the case if it gets wet, as damp breeds smears and speeds up hinge corrosion
A city break is kinder than a beach week, but a Toulouse to Paris train ride with a crowded luggage rack can still do plenty of damage to an unprotected pair.
Which glasses are easiest to travel with?
Frames that flex and lenses that do several jobs make the best travel companions. A flexible memory-metal frame such as Delicate - Gold tolerates the odd squeeze in a bag far better than a rigid thin metal frame. For a lighter pair on your face all day, higher lens indices (1.61 or 1.67) give thinner lenses for stronger prescriptions. Photochromic lenses darken outdoors, so you carry one pair instead of two. Behind a car windscreen they darken less, so do not count on them for driving. Magnetic clip-on frames such as the Magneto 3-in-1 or the Polyhedron 4-in-1 turn one prescription frame into sunglasses and a blue light filter, which saves space in the bag. We would pick the 4-in-1 for a trip with long train rides and a lot of screen time.
| Trip type | What we would pack |
|---|---|
| City break | Everyday frame plus a spare, such as Hawk or Slati |
| Sun and beach | Prescription sunglasses (Coastal, Amber) or a clip-on set |
| Ski trip | Alpine snow goggles, night vision lens included |
| Active holiday | CourtSharp or DunkVision sports glasses |
| Long work trip | Frame with anti-reflective and blue light filtering lenses |
Where can you get a travel-ready pair before you leave?
Order early. Most Lensdy orders arrive within 1–2 weeks, so place yours at least three weeks before departure to leave room for a check at home. Lensdy has frames in acetate, metal, titanium, rimless and flexible memory metal, with affordable prescription lenses and free shipping on orders over €59. A second pair for the suitcase often clears that threshold on its own. If you want something with a bit of colour that stands out in a crowded hotel breakfast room, Serein Purple is easy to spot and hard to leave behind. Browse the full Prescription Glasses collection and pick a sturdy frame for the road.
Frequently Asked Questions
Can I put my glasses in checked luggage?
We would not. The hold is the most common place for crushed frames and lost cases. Keep your glasses and your spare pair in your cabin bag or on your face.
Do airport X-ray machines damage glasses?
No, security scanners do not damage lenses or coatings. The risk is the tray, where glasses slide off or get lost under other items. Keep them in their case.
Do I need a hard case if I have a soft pouch?
For flying, yes. A pouch stops scratches but not pressure from a squeezed bag. Use the pouch inside the hard case if you want an extra layer, especially with rimless frames.
Should I bring my prescription when I travel?
Yes. Keep a photo on your phone and a paper copy in your wallet, including your PD. If your glasses break abroad, you can order a replacement online without booking an eye test.
Should I wear glasses or sunglasses on a long drive abroad?
Use whichever gives you clear, comfortable vision for the conditions. Prescription sunglasses are better than photochromic lenses in a car, as photochromic lenses darken less behind a windscreen. Ask your optician about night driving.
What should I do if my glasses break abroad?
Switch to your spare pair and use your prescription photo to order a replacement online. If a screw is loose, tighten it with a small screwdriver and avoid bending a snapped frame back into shape.
