How to choose a swim goggles
Updated June 2026Independently researchedNo paid placement.
Choose swim goggles by balancing fit, lens type, and intended use: for laps in a pool, look for a low-profile design with clear or lightly tinted lenses and reliable anti-fog; for open water, pick polarized or mirrored lenses with a wider field of view and UV protection. A secure, comfortable seal is non-negotiable, test before you buy if possible.
What lens tint is best for pool vs open water?
For indoor lap swimming, clear or lightly tinted lenses work well because lighting is consistent and you rarely need glare reduction. Many experienced pool swimmers prefer clear or smoke-tinted goggles that let in plenty of light without distortion. In open water, lakes, oceans, or rivers, glare from the sun can be harsh, and UV protection matters. Mirrored or polarized lenses cut glare significantly and help you see beneath the surface more clearly. Some open-water swimmers also opt for amber or rose-tinted lenses, which enhance contrast in variable light conditions like cloudy days or early morning swims. If you swim both indoors and outdoors, consider a model that comes with interchangeable lenses, or buy a separate pair for each environment. Spending the extra money on a dedicated open-water goggle with UV protection is worth it for comfort and eye safety under the sun.
How to ensure a leak-proof seal?
A goggle’s seal depends on the gasket material and how well it conforms to your face. Silicone gaskets are the most common and durable; they provide a soft, flexible seal that lasts longer than foam or rubber alternatives. Foam gaskets, while initially comfortable, can degrade quickly in chlorinated water and may need replacement sooner. To test fit, press the goggles gently against your eyes, without the strap, and release. If they stay suctioned for a moment, the seal is good for your face shape. When you put them on, the strap should hold them snug but not tight enough to leave deep marks. Eye sockets differ, so try several brands (Speedo, TYR, Arena, Aqua Sphere) because each has a slightly different contoUr. Swimmers with deeper-set eyes or high cheekbones may find that certain Scandinavian-style goggles (like those from Malmsten) offer a better anatomical fit. For kids or people with narrow faces, look for goggles labeled “small fit” or “junior” – the bridge width and gasket size matter just as much as the strap adjustment.
Do I need anti-fog coating?
Yes – virtually all modern swim goggles come with an anti-fog coating on the inner lens, but it wears off over time. A fresh coating prevents condensation from fogging up your view, which is critical for safety in open water and for keeping a clear sight during interval training. The reality is that no anti-fog lasts forever. Chlorine, salt water, and even your own fingers rubbing the inside of the lens can degrade it. Some swimmers use anti-fog sprays or drops to extend the life, but many find they simply buy a new pair every few months. To protect the coating, never rub the inside of the lenses. Rinse goggles with fresh water immediately after each swim and let them air dry in the shade. If you do need to clean the inside, use a gentle lens cleaner made for goggles, or just a drop of baby shampoo rubbed in and rinsed off.
What strap and adjustment features to look for?
Basic strap designs have a single split-back band with a simple buckle, but many goggles now include a ratcheting or quick-release system that makes it easier to adjust the tightness even while wearing them. For open water, a wider, textured strap that grips the back of your head is less likely to slip off during a dive or a rough wave. Look for straps that are made of silicone or a silicone-blend – they resist chlorine and UV better than rubber, and they won’t pull your hair as much. The standard design also has a tab or clip to adjust the strap length on each side; this is fine if you only share goggles occasionally. Some triathlon or open-water goggles have a spring-loaded or “bungee” strap that automatically adjusts to tension, which many athletes find comfortable for long swims. However, these can be harder to replace if the strap wears out, so weigh convenience against longevity.
How to choose goggle size and shape for your face?
Goggle sizes generally fall into three categories: low-profile (small lens), medium (most common for adults), and wide-field (larger lens for better peripheral vision). Low-profile goggles sit closer to the eye socket and create less drag; they are popular among competitive pool swimmers who want a streamlined feel. Medium-profile goggles offer a good balance of comfort and vision for lap swimming and recreational use. Wide-field goggles, often with a single lens or large dual lenses, give you great peripheral awareness, making them a strong choice for open water swimming where you need to see buoys, waves, and other swimmers. However, larger lenses create more water resistance when turning your head, and they may seal differently on narrower faces. To find your size, you can’t rely on one brand’s “large” vs another’s – try them. A well-fitting goggle creates a uniform seal all around the eye socket without pressing directly on the eyeball. If you have a low nose bridge, look for goggles with adjustable nose bridges; many models come with three interchangeable nose pieces to fine-tune the fit.
Should I worry about UV protection and polarisation?
For outdoor swimming, UV protection is important to prevent long-term eye damage from the sun’s reflection off the water. Most swim goggles made from polycarbonate lenses block 99–100% of UVA and UVB rays, but you should check the product description to confirm. Even if you swim in overcast conditions, UV exposure is still present. Polarised lenses reduce glare from horizontal surfaces – like the surface of the water – which makes them especially valuable for open water. They help you spot obstacles, judge depth, and see the bottom in clear water. But polarisation can also make it harder to read digital lap counters or see through some boat windshields, so if you do podium swims in a pool with a pace clock, you may prefer non-polarised lenses. If you swim mostly in a covered pool, UV protection is a lower priority, but many goggles still include it as standard. For open water, look specifically for “UV400” or “100% UV protection” labels, and lean toward mirrored or dark-tinted lenses for bright conditions.
Frequently asked questions
Can I wear contact lenses under swim goggles?
Yes, many swimmers wear soft contact lenses under goggles, provided the goggles fit tightly enough to prevent any water from finding its way in. Even a tiny splash can wash out a lens, so look for goggles with a good seal and consider a strap that holds the goggles firmly. Discard daily lenses after a swim, and avoid wearing RGP (rigid gas permeable) lenses in the water unless you have custom-fitted dive masks.
How often do I need to replace my swim goggles?
It depends on use and care, but most swimmers replace their main pair every 3 to 6 months if they swim several times a week. The anti-fog coating is the first thing to go, and silicone straps or gaskets can start to stiffen or crack after prolonged chlorine or sun exposure. When you notice fogging that you can’t fix or water leaking in, it’s time for a new pair.
What is the difference between pool goggles and open water goggles?
Pool goggles tend to be narrower, with smaller lenses and a lower profile to minimise drag when you push off walls. They may be less tinted because pool lights are controlled. Open water goggles usually have larger lenses for a wider field of view, darker or mirrored tints for sun glare, and sometimes UV protection built in. The strap design is often more secure on open-water models to withstand waves and dive starts.
Do mirrored goggles help with visibility in open water?
Yes, mirrored lenses reflect sunlight and reduce glare, which can make it easier to see navigation buoys and the water surface. They also help keep your eyes cool in bright conditions. Keep in mind that mirrored coatings can scratch easily, so handle them carefully and rinse with fresh water after every use.
How can I keep my goggles from fogging up?
First, never touch the inside of the lenses. Rinse goggles in cold (not hot) water before each swim to pre-wet the lens. If fog starts despite that, use a commercial anti-fog spray or a drop of unscented baby shampoo – rub it in, rinse gently, and let dry. Some swimmers also lightly lick the inside of the lens (saliva works as a temporary surfactant), but that can introduce germs and you’ll need to rinse again.
Are there prescription swim goggles for nearsighted swimmers?
Yes, many brands offer goggle lenses in diopters (typically from -1.5 to -8.0). You can buy them as separate lenses that snap into compatible frames, or as ready-made presription goggles. Custom optometrist-made goggles exist but cost significantly more. For most people, a diopter closest to their everyday prescription (or slightly weaker) works well, because water optics magnify vision a bit.
