HOW TO CHOOSE SWIMMING GOGGLES (10 THINGS THAT ACTUALLY MATTER)

Swimmers usually use three pieces of equipment: swimsuit, swim cap, and swim goggles.

Goggles are the one piece of kit most swimmers get wrong. Not because they buy bad ones, but because they buy ones that don't fit their face - and then assume all goggles are like that. The right pair makes swimming clearer, more comfortable, and faster. The wrong pair leaks, fogs, and leaves marks around your eyes for an hour.

So what do swimming goggles actually do? They keep water, chlorine and salt out of your eyes so you can see clearly underwater, and they let you swim with your face in the water, which is where good technique starts.

Key Takeaways:

• A 5-second test in the shop, with no water and no strap, tells you whether goggles will leak.
• Foam seals feel soft at first but wear out faster than silicone, and here is what to look for instead.
• Smart goggles can now track your head position and breathing, so you can see for yourself whether your head is why your legs sink.

1. What Are You Going to Use Them For?

Open water swimming (triathlon), indoor, or outdoor pool swimming. Depending on where you’ll swim, you’ll want different lens colors and features.

Indoor swimmers might not need dark goggles unless the lighting is intense.

Outdoor swimmers, on the other hand, benefit from polarized or mirrored lenses with UV protection to reduce glare and protect your eyes from the sun. If you swim in open water, pair your goggles with a brightly coloured swim buoy - it makes you visible to boats and gives you something to hold onto if you need a rest.

Quick Reference: Goggles by Use

Types of Swimming Goggles

Most goggles fall into a few types, and each has a different job:

• Racing goggles are small and low-profile for minimal drag. They sit close to your eyes, but the tight seal can cause eyelash friction or bruising if you wear them too tight.
• Training goggles are the all-rounder most pool swimmers buy. A bit bulkier than racing goggles, but more comfortable for longer sets.
• Mask-style goggles have a larger seal and a wider field of view. They are easier to fit and less prone to leaks, which makes them a good pick for beginners, recreational swimmers and open water.
• Prescription goggles have corrective lenses built in, for swimmers who can't see the wall or the clock without glasses.
• Custom-fitted goggles are 3D-scanned to your face for a personalised seal.
• Smart goggles track your swim data.

Lens Color and Protection

• Clear lenses: Best for indoor or low-light conditions.
• Tinted lenses: Reduce brightness, great for partially sunny pools.
• Mirrored lenses: Ideal for bright outdoor swimming and open-water events.
• Polarized lenses: Cut glare on water surfaces, especially useful for triathletes.

If you swim outdoors, always make sure your goggles offer UV protection to protect your eyes from long-term damage.

2. Size of the Gasket

Usually, the smaller the better as you have less resistance in the water, but they also have to be comfortable, so don’t get too hung up on size alone.

The suction test: before buying, press the goggles gently against your eyes without putting the strap on. If they stay in place for a few seconds on their own, the gasket shape matches your face. If they fall off immediately, no amount of strap tightening will fix the leak - you need a different model. This is the single most useful thing you can do in a shop before buying.

If small goggles feel too tight or you want a wider field of vision, you can go for larger, mask-style goggles that cover more area.

At the end of the day, it all comes down to comfort and fit.

Lens Shape and Visibility

Modern goggles come in different lens shapes:

• Flat lenses: Minimal distortion, better for pool use.
• Curved lenses: Provide better peripheral vision for open-water or triathlon swimming.

If you swim in crowded lanes or murky water, curved lenses help you see more of what’s around you.

3. Type of Seal Material

These are the pieces that actually touch your skin around the eyes and create suction.

Usually, rubber or silicone is the best as they seal well without letting water in. Silicone is durable and comfortable, but a bit pricier. Foam seals can work too, but they deteriorate faster and may cause skin irritation.

What About Foam Seals?

Foam is the old-school way to make a goggle comfortable. Before silicone gaskets took over, foam padding around the lens was what most swimmers wore, and you still find it in some cheap goggles today..

Foam feels soft and comfortable out of the package, which is why it sold so well. The catch is how it ages. Foam gradually shrinks, hardens and loses its cushion, so the seal gets worse and the goggles start to leak. Tightening the strap to compensate just leaves you with pressure marks around your eyes. Some swimmers also get skin irritation from foam.

If you already own foam goggles and they still seal well, there's no need to throw them out. Once the foam flattens or the goggles start leaking, replace them. If you're buying new, I'd go with silicone.

Anti-Scratch Coating

While you’re checking for anti-fog, look for anti-scratch coatings as well. Especially if you often toss your goggles into a gear bag. It’ll keep your lenses clear for longer.

4. How Do They Sit on Your Eyes?

Are they too big or too small? Do your eyelashes touch the lenses when you blink?

One thing to consider is how long you’ll wear them. For quick 30-minute pool sessions, it’s less critical. For long open-water swims, soft silicone seals and low pressure on your eye sockets are essential for comfort.

It also helps to know where the goggle actually sits on your face. Small racing goggles and old-school Swedish goggles press right around the eye socket, on the bone, which is why they feel hard and can leave marks if you wear them for long. Mask-style goggles sit further out on the brow and cheekbones and spread the pressure over a bigger area, which is why many beginners find them kinder. If a pair always leaves marks or makes your face sore, this is often the reason, and it's worth trying a different style before giving up on goggles altogether.

If you swim in both the pool and open water, consider owning two pairs. One for comfort, one for performance.

5. Fit Around the Nose

Do they hurt your nose or you cannot even feel them on your nose?

Good goggles shouldn't pinch the bridge of your nose or dig into bone. The bridge should span the gap naturally without pulling the eye cups inward or pushing them apart. That is why it is also important to try before you buy.

Some goggles have larger nose pieces, so people with higher nose bridges are happier.

Make sure it is possible to adjust the nose piece. If it is not possible, then you need to test them out before you buy them for sure. Otherwise, you cannot be sure they will fit you since you cannot adjust it.

6. Type of Strap

Is it adjustable to fit your head?

Usually, the straps are ok and can be adjusted just fine.

For adults, a double strap is quite standard. For kids, ideally, the strap is a bit larger, so it is easier to untangle from the hair :).

However, beware of bad quality material used to make the strap. The way you tell is by stretching a piece of the strap very tight and see if the black color of the strap turns white (or shows stress micro-tears). If yes, then the strap is not made out of quality material.

Of course, you can always DIY replace the strap with another, so that should not stop you from buying the goggles that fit you well :).

7. Do You Need Prescription Goggles?

This is probably not that important for most people with very cheap contact lenses out there, but there are also goggles with prescription.

So, if you cannot see the swim clock or worse, the wall, and you don't wear contact lenses, you can get goggles in your prescription strength, and most come in pre-set steps, so pick the closest one.

Here is an interesting pair of prescription goggles, where the lenses are just snapped inside the mask, so easily replacable and usable in other goggles/masks.

7.1 Custom-Fitted Goggles for Perfect Seal

Struggling to find goggles that fit? Are they always leaking, pinching, or leaving deep red rings? You might want to consider custom-fitted goggles such as THEMAGIC5 goggles.

These goggles are 3D-scanned and manufactured to match the unique contours of your face, creating a personalized fit that eliminates pressure points and leaks.

The scanning process takes less than a minute using their mobile app, and once produced, the goggles feel like they were molded just for you.

They’re ideal for both pool and open-water swimmers who want maximum comfort and clear vision without constant adjustments.

No leaks, no suction pain, just a natural seal and better comfort for long swims.

I know this sounds like marketing mumbo jumbo, but they really do work. I've been swimming in a pair for over 2 years now, mostly in the pool, and they have not given me trouble once.

8. Do They Fog Up?

This is tricky to test in-store, but bad goggles fog up quickly.

Why do goggles fog in the first place? It's plain condensation: your warm face heats the air inside the goggles while the water cools the lens, so moisture collects on the inside.

If yours fog up, spit into them or lick them before swimming. It's an old trick that somewhat works! A drop of diluted baby shampoo, rubbed on the inside of the lens and rinsed off well, is another option many swimmers use.

However, don't do either of these immediately after purchase. Quality goggles come with a thin anti-fog coating that you don't want to damage too soon. Wait until it wears off.

9. Try Before You Buy (Or Make Returns Easy)

You can't judge a goggle's fit by looking at it, so try them on when you can. A shop that lets you open the pack and do the suction test is worth the extra few dollars.

If you're buying online, which is how most people buy goggles these days, choose a seller with an easy returns policy so a pair that doesn't fit isn't wasted money.

10. Consider the Price

The range is just amazing. From under 10 bucks to hundreds.

You can’t go wrong with the classic Swedish goggles for as little as $10. They’re simple, adjustable, and last forever if you take care of them.

How to Make Your Goggles Last

You finally found a pair that fits, so how do you keep it that way? Goggles don't ask for much, but a few lazy habits will kill a good pair in a couple of months.

Rinse them in fresh water after every swim. Chlorine and salt don't do your goggles any favours, and it takes five seconds at the tap.

Let them air dry and keep your fingers off the inside of the lenses. That thin anti-fog coating is the first thing to go, and wiping it with your thumb or a towel is the fastest way to rub it off.

Don't toss them loose into your gear bag. Lenses get scratched in there before you even reach the pool. A small case or pouch costs next to nothing and keeps them clear.

So when is it time to say goodbye? Replace your goggles when:

• The lenses are scratched enough that the lane line looks fuzzy
• The anti-fog coating is gone and they fog up every length
• They leak even though they used to fit just fine

What about a worn-out strap? Nah, don't buy new goggles just because of that. A new strap costs next to nothing, so replace the strap and keep the goggles.

If you swim often, that usually means a new pair around every 12 months, depending on the quality and how well you look after them. A fresh pair once a year is cheap insurance against a ruined swim.

Common Goggle Buying Mistakes

Most bad goggle purchases come down to the same handful of mistakes. Here is what I'd watch out for.

1. Buying on price or brand alone A $200 pair that doesn't fit your face is worse than a $10 pair that does. Cheap doesn't automatically mean bad, and expensive doesn't automatically mean good. The only price that matters is what you pay for a pair you'll actually wear.

2. Copying a friend's (or a pro's) goggles Your swim buddy swears by theirs? Great for them. Your face is not their face, and a pair that seals perfectly on one swimmer can leak constantly on another. Borrow the idea, not the pair, and do the suction test before you commit.

3. Tightening the strap to stop a leak It's the first thing everyone tries. Check that the strap sits level and the nose piece is adjusted evenly first. If it still leaks, the gasket shape probably doesn't match your face, and cranking the strap mostly gives you pressure marks and a headache while the water still sneaks in. Try a different model instead.

4. Wearing racing goggles for everything Small, low-profile racing goggles look fast, and they are, but that tight seal can bite into your eye sockets over a long session. For everyday training or long open water swims, a comfortable training pair or a mask-style goggle is the better choice.

5. Messing up the anti-fog coating on day one New goggles come with a thin anti-fog coating, and the urge to rub the lenses or lick them before the first swim is strong. Don't. Leave the coating alone until it wears off, then rinse gently or use an anti-fog spray.

The pattern behind nearly all of these: fit comes first. Price, brand, colour and fancy features are the bonus.

Bonus: Smart Goggles (With and Without a Display)

If tracking your swim data matters to you, smart goggles have come a long way - and there are now two main approaches worth knowing about.

Form Smart Swim 2 shows real-time metrics like pace, distance and stroke count directly in an AR display inside the lens while you swim - no need to stop and check your phone.

Speedo iQ takes a different approach: no display, but a removable sensor module built into the Vanquisher 3.0 that tracks head position, breathing angle, turn time and stroke data across all four strokes, then syncs to an app after your session. Particularly useful if you want to analyse your head position - something most swimmers never get feedback on until they see the data.

Form starts at $149 for the Smart Swim 2 LT (the standard Smart Swim 2 is $199), and Speedo iQ is $189. Overkill for casual swimmers, but for a triathlete who wants to see whether head position is why their legs sink, the data might be worth it. (See our guide on correct head position in freestyle to understand what the data is actually measuring.)

🖼️ The Goggle Fit & Lens Selection Guide

Sometimes it helps to see the gear specs side-by-side. We have put together this quick-reference visual cheat sheet to help you compare socket placement (inner-socket vs. mask-style) with lens coatings (clear, mirrored, polarized).

Review this guide to see exactly which combination fits your facial bone structure and your swimming environment before your next shopping trip.

If you remember one thing from all of this, make it fit. Do the suction test, ignore the price tag and the brand name, and pick the pair that feels comfortable on your face. Everything else is a bonus.

Got your goggles sorted? The next piece of kit worth a thought is the swim cap, and whether you actually need one.

Happy swimming!
