How to choose sunglasses for a trip
Five criteria, ordered by what actually ruins a pair of sunglasses on holiday rather than by what a product page leads with.
1. Replacement cost, which is the real spec
Work out what you would feel on the morning you cannot find them. Under about forty dollars, the answer is irritation; over about two hundred, it is a genuinely bad day in the middle of a holiday. That number should drive the purchase more than lens marketing does, because the failure mode you are actually insuring against is loss, not glare.
It is also why the two-pair approach wins. Two polarized UV400 pairs at twenty to forty dollars each cover the whole trip with a spare in the bag and still cost less than one mid-range frame. If you want the arithmetic in more detail, our what a $200 pair is actually buying breaks the price down by what it adds and what is pure brand.
2. The UV rating has to be stated
The non-negotiable. The AAO’s buying guidance is to look for lenses marked as blocking 100% of UV or UV400, and the CDC puts the same number on it: block 99–100% of both UVA and UVB. Resort shops and airport kiosks are the single worst place in the world to buy sunglasses, because a dark lens with no UV filter is worse than no sunglasses at all — it opens your pupil and then passes ultraviolet through the larger aperture. Buy before you fly. Every pick on this page states its rating; our guide to testing a pair for UV covers what to do about the pair you already own.
3. Will it survive the bag?
Travel damage is mostly crushing and heat, not scratching. A polycarbonate or TR-90/Grilamid frame flexes and comes back; acetate and metal do not, and a metal hinge that gets bent in a daypack stays bent. Polycarbonate lenses are also the impact-resistant option, which is the right trade for a trip even though glass is optically clearer — our glass vs polycarbonate guide covers why glass belongs on a boat and not in a carry-on.
A hard case solves most of this and weighs almost nothing. If you take one thing from this page other than a pick, take that: the case is a bigger upgrade to a cheap pair than another thirty dollars of lens is.
4. One pair, four jobs
A travel pair gets asked to do more than any other: a plane window, a city afternoon, a rental car, water. That argues for a mid-grey or brown polarized lens in filter category 3 — the do-everything tint — rather than anything specialised. A very dark category 4 mountain lens is wrong here, and not just stylistically: category 4 is generally marked as unsuitable for driving, so it fails the rental-car leg outright. If your trip really is a glacier, that is the one travel case with a different answer and it has its own page at best glacier glasses.
Polarization is worth having for the water and the drive. The one place it works against you is an aircraft cockpit instrument panel or a phone screen in portrait orientation, which is a minor annoyance rather than a reason to skip it — see polarized lenses and screens if that irritates you enough to plan around.
5. Retention, in the places where losing them means losing them
On a boat, a paddleboard or a cliff path, “lost” is permanent. A grippy temple or a cord fixes it for almost no money; a floating frame fixes it properly, and our floating sunglasses roundup ranks the pairs that come back up. If your trip is mostly on water, buy from that page instead of this one.
The two-pair system, concretely
For most trips: one polarized UV400 pair you wear, and one identical or near-identical spare in the luggage. If the trip has a water component and a city component, split them — a wrapped sport pair for the water and something flatter for the evenings. For a group or a trip long enough that losses are a certainty, a multipack is not a joke purchase: six UV400 polarized pairs for the price of one mid-range frame is a rational answer to a known attrition rate, and it is the reasoning behind the third pick below.
What we would not do is travel with a single two-hundred-dollar pair and no backup. That is the configuration where one careless moment costs you both the money and the sun protection for the rest of the trip.
What we checked and did not feature
Sunglasses cases and travel accessories. Two of the ten autocomplete suggestions for this topic are about cases rather than sunglasses, and a hard case is genuinely the best few dollars you can spend on a travel pair. We do not rank cases, because our registry is eyewear and we are not going to invent a product family to fill a slot. Buy any rigid case that closes properly.
Premium polarized frames in the $150–300 band.Several of the best lenses we cover — Maui Jim, Costa, the polarized Ray-Ban trims — are excellent and are the wrong answer to this question. They are ranked on the flagship roundup and in the brand reviews, where the question is which lens is best rather than which pair survives a fortnight of being mislaid.
Fit-overs and clip-ons for glasses wearers. A real travel problem and a different page. If you wear prescription glasses, the cheapest way to have sunglasses on a trip is a clip-on that lives in the same case, and our clip-on roundup and fit-over roundup both rank pairs under thirty dollars.
