Most sunglasses are water-tolerant, not waterproof. A few raindrops, a splash from a paddle or a rinse under the tap will not hurt a well-made pair. Long soaks, swimming, saltwater and hot, wet storage are where frames, hinges and lens coatings start to wear. Below, we explain what water actually touches on a pair of sunglasses, what to do after a soaking and what to check before you take a pair near a lake, a pool or the ocean.
TL;DR
- Sunglasses can get wet. Rain and splashes are fine for most pairs, but “can get wet” is not the same as “made to be submerged”.
- Water repellency on a lens is a cleaning feature. It helps droplets bead and wipe off. It does not make a pair waterproof.
- Saltwater is the harder test. Rinse with fresh water afterwards, pat dry with a microfiber cloth and store the pair in a case.
- Polarization and UV protection are two separate things. Polarization cuts glare off water, and UV protection should be chosen on its own.
- Check the maker’s care instructions before swimming, diving or leaving a pair in a wet bag.

What “waterproof” means for sunglasses
No industry label tells you a pair of sunglasses is waterproof the way a phone or a watch carries a rating. When people ask whether sunglasses are waterproof, they usually mean one of three things:
- Will rain or sweat ruin them?
- Can I wear them on a boat, a paddleboard or a beach without worrying about splashes?
- Can I swim or dive in them?
The honest answer changes with each one. For the first, almost always yes. For the second, usually yes if you look after them. For the third, only if the maker says the pair is designed for it. Ordinary sunglasses are built to be worn on your face in the open air, not to sit underwater.
There is also a practical point. Sunglasses sit on your face to cut glare and block UV. A pair that is wet and covered in droplets does that job badly, and goggles do the underwater job better. If swimming is the plan, that is a different piece of gear.
What water touches on a pair of sunglasses
A pair of sunglasses is several parts, and each reacts to water in its own way.
Lenses and coatings
The lens itself, whether glass or a plastic such as polycarbonate, is not harmed by a quick wetting. The surface layers are what vary. Lenses can carry coatings for scratch resistance, glare, smudges and water. ZEISS Canada describes water-repellent, anti-static and anti-smudge coatings as features that make lenses easier and quicker to clean. That is what a water-repellent coating does: droplets bead up and slide off, so the lens clears faster and wipes cleaner. It is a convenience, not a waterproofing system for the whole pair.
If you want to know more about coatings that fight droplets and fogging, our guide to anti-fog sunglasses coatings covers what works and how long it lasts. For the scratch side of the story, see our comparison of scratch-resistant lens coatings and materials.
Polarized lenses
Polarization is about light, not about water resistance. ZEISS describes polarization as glare reduction on reflective surfaces such as water, which is why polarized sunglasses are a favourite for boating, fishing and the beach. A polarized filter makes the surface of a lake easier to look at. It does not change how the pair behaves when it gets wet.
If you are choosing a pair for the water, our short checklist of specs for polarized water sports sunglasses walks through what to look for. And if a lens ever looks hazy or streaky after a lot of wet use, the cause is often residue rather than damage. Our solvent-free way to clean polarized lenses takes about 90 seconds.
Frames, hinges and screws
Frames are where materials matter most. Plastic and nylon-type frames shrug off a wetting. Metal parts, especially small hinges and screws, are the places where moisture, and salt in particular, can collect and cause trouble over time. A hinge that is full of dried salt becomes stiff or gritty, and a loose screw is one of the most common ways a pair stops fitting well.
That is one reason we build our frames the way we do. Our foldable frames use a patented micro hinge and a screwless design, which is meant to give you a compact, durable pair with fewer small parts to work loose. It is a design choice for carrying and daily use, and it suits the way people pack sunglasses for trips.
Temperature and wet storage
Water is rarely the only factor. A wet pair left on a hot dashboard, or sealed damp in a bag for a day, gets both heat and trapped moisture. Heat is hard on coatings and on frame materials, so a wet pair is best dried before it goes into a case or a pocket.
Rain, splashes, sweat: normal wear
Rain and sweat are the everyday cases, and they are fine. Sunglasses are made for outdoor use, and that includes weather. A few things make life easier:
- Shake, then wipe. Shake off the big droplets first. Wiping a wet lens with a dry cloth can drag grit across it.
- Use a clean microfiber cloth. A cloth that has been in a pocket full of sand is a scratch waiting to happen.
- Do not wear tinted lenses for rainy-day driving at dusk. Tinted lenses cut light. When the light is already low, a lighter lens or none is the safer choice.
- Let the pair air dry open before folding it away.
If you travel a lot, a pocket-sized routine helps. Our guide to three fast ways to clean sunglasses on the road includes a small kit you can keep in a carry-on.
Pools, lakes and the ocean
This is where the “are sunglasses waterproof” question really bites.
Swimming and diving
Sunglasses are not swim goggles. They are not designed to seal against your face, they are not built for pressure, and they float away or sink the moment you dive. A pair that is not made for swimming should stay out of a pool or the open water. If your plans include swimming in lakes or the ocean, read up on staying safe first: this guide to open-water swim safety covers lakes, ocean and group swims.
Chlorine
Pool water is a mild chemical bath. A quick splash while you sit on a lounger is no problem. Leaving a pair soaking in pool water is a different matter, so rinse and dry after any contact.
Saltwater
Saltwater is the one to respect. Salt dries into crystals on lenses and frames, and those crystals scratch when you wipe them off dry. They also get into hinges. If you are asking whether frames are safe in saltwater, the sensible answer is that salt exposure is something you manage, not something to ignore. The routine is simple:
- Rinse the pair under cool, fresh tap water as soon as you can. Do not wipe it dry first.
- Gently rub the lenses with a drop of mild dish soap if they feel tacky, then rinse again.
- Open and close the hinges once under the water to flush out grit.
- Pat dry with a clean microfiber cloth.
- Leave the pair open to air dry for a few minutes, then put it in its case.
On boats, a lanyard or retainer strap is a cheap insurance policy. The most common way people lose a pair on the water is not damage but a splash, a gust of wind and a plop.
If you are choosing a pair for a trip near water, see our overview of packable UV400 sunglasses for high-UV destinations, which includes three foldable models.
How to clean and dry sunglasses after they get wet
The goal is to remove water, salt and grit without scratching anything.
| Situation | What to do first | What to avoid |
|---|---|---|
| Light rain or sweat | Shake off droplets, wipe with clean microfiber | Wiping with a shirt or paper towel |
| Pool splash | Rinse in fresh water, pat dry | Leaving it to dry with chlorine residue |
| Saltwater or sea spray | Rinse thoroughly in fresh water, flex hinges under the tap | Dry-wiping salt crystals off the lens |
| Sandy beach | Rinse or blow off sand before wiping | Rubbing sand across the lens |
| Soaked and stored damp | Open the pair, dry fully, then case it | Closing it into a sealed bag or hot car |
A few extra habits keep a pair going longer:
- Use lukewarm water, not hot. Heat is harder on coatings.
- Skip household glass cleaners, alcohol wipes and solvents on coated lenses unless the maker says they are fine.
- Store the pair in a case, not loose in a bag.
- If a lens looks cloudy, spotty or peeling at the edges after repeated wet use, stop using it near water and ask the maker or an optician. Water getting into the layers of a lens is a manufacturing and warranty question, not something to fix at home.
What to check in the care instructions
Before you take any pair near water, a minute with the care card or product page pays off. Look for:
- Water use guidance. Does the maker say the pair can be worn around water or for water sports? If it says nothing about swimming, treat it as a no-swim pair.
- Frame material. Plastic, nylon and metal each have different needs. Metal parts and small fasteners are the ones to rinse well after salt.
- Lens coatings. Water-repellent, anti-smudge and scratch-resistant coatings change how you clean the pair.
- Cleaning advice. Which cloth, which soap, what to avoid.
- Warranty terms. Look at what the warranty says about water, salt and wear.
- Included case or pouch. A pouch that handles damp, like the waterproof pouches that come with our pairs, is handy for getting a wet pair back into a bag without soaking everything else.
Protection from the sun is a separate question
It is easy to confuse “water-friendly” with “protective”. They are different checks. The Waterdown Optometric Clinic in Ontario explains that polarization and UV protection are separate: polarization reduces glare, while protection against UVA and UVB should be chosen on its own. On the water, UV is stronger than people expect because sunlight bounces off the surface, so confirm the UV rating even if the lens is polarized and looks dark.
Two of our guides help here: how to verify that sunglasses block UVA and UVB, even in foldable pairs, and five quick checks to confirm UV400 protection.
Your skin gets the same sun your eyes do. If you spend long days outside, a sun balm for outdoor work covers the skin around the eyes that sunglasses leave exposed.
Our perspective
We design sunglasses for people who move: travellers, paddlers, hikers and anyone who has ever sat on a pair at the bottom of a bag. Water is part of that life, so we think about it practically.
Our frames use a patented micro hinge that folds down to a very compact size, and they are screwless. For us, that is about durability and convenience. There are fewer small parts to loosen, and the pair slips into a pocket instead of living in a bulky case. It is also why we include a waterproof pouch: a damp pair can go into your bag without soaking everything else.
Our advice is simple. Treat any pair of sunglasses as water-tolerant, not waterproof. Rinse after salt, pat dry, case it, and keep the UV protection and the polarization in your mind as two different jobs. Do those four things and a good pair will keep going through a lot of trips.

Picking a pair for water days
If your plans include boats, beaches or paddling, these are the criteria worth weighing:
- UV protection first. Look for UVA and UVB blocking, such as UV400.
- Polarized lenses for glare off the water, which makes long days on a boat or lake less tiring.
- Frames you can rinse. Fewer small parts and a simple design are easier to flush out.
- A secure fit. Wind and movement are what lose sunglasses on the water, so pick a fit that stays put and consider a retainer strap.
- Compact carry. A pair that folds small is easier to stash dry in a pouch when you step off the boat.
For a longer outdoor trip, our guide to packable sunglasses that stay put on safari shows how we think about fit and packing, and it applies on a lake too.

FAQ
Are sunglasses waterproof?
Generally no. Most sunglasses handle rain, sweat and splashes, but they are not made to be submerged. Unless the maker says a pair is designed for swimming or water sports, treat it as water-tolerant and rinse and dry it after any soaking.
Can sunglasses get wet?
Yes. Wearing sunglasses in the rain or near a lake is fine. Shake off the droplets, wipe with a clean microfiber cloth and let the pair dry open before folding it away. Avoid leaving a wet pair sealed in a bag or a hot car.
Are sunglasses frames safe in saltwater?
Saltwater exposure is something to manage. Salt crystals can scratch lenses and collect in hinges, so rinse the pair in fresh water as soon as you can, flex the hinges under the tap, pat dry and store it in a case. Check the maker’s care instructions for your frame material.
Does a water-repellent lens coating make sunglasses waterproof?
No. ZEISS Canada describes water-repellent coatings as features that make lenses easier to clean. Droplets bead and wipe off more easily, but the coating does not protect the frame, hinges or the whole pair from soaking.
Do polarized sunglasses help you see through water?
Polarized lenses cut glare off reflective surfaces such as water, which can make the surface easier to look through. They are a glare tool, not a waterproofing feature, and UV protection should still be checked separately.
