How to stop swimming goggles from fogging up

One word: condensation.

Swimming goggles fog up because of condensation, where the warm, moist air from your face (or perspiration) encounters the cooler surface of the goggles, causing water vapour to condense and form a film on the lens. Science.

Now that's cleared up (pun intended), let's get into how to stop your goggles from steaming up, and how to remove the fog if it does.

Sounds obvious (and it is), but this is one of the most effective solutions is using an anti-fog spray. Designed specifically to prevent condensation, these sprays create a thin protective layer on the inside of your goggles.

Simply spray, rinse lightly (if required by the product), and enjoy clear lenses for longer. An Anti-Fog Re-Activator is a great option to keep fog at bay.

It may not sound glamorous, but spitting into your goggles is a tried-and-tested method used by swimmers for years. (It’s also free).

Spit creates a thin film that prevents water droplets from forming into fog. Simply rub the saliva around the lenses and rinse lightly before putting them on.

A tiny drop of baby shampoo can work wonders for keeping your goggles fog-free. The gentle formula creates a barrier on the lenses that stops condensation.

Rub a small amount inside the lenses, rinse briefly with water, and you're good to go. Just be sure not to use too much, as you don’t want irritation while swimming.

Before putting your goggles on, splash your face with cool water. This helps equalise the temperature between your skin and the goggles, reducing the chances of fogging.

This simple trick can make a big difference, especially in colder pools.

If you’re mid-swim and fog starts forming, a quick rinse in the pool can provide temporary relief.

While it won’t prevent fogging for long, it can help you regain clarity for a few more laps.

Looking after your goggles properly will help maintain their anti-fog properties. Avoid rubbing the inside of the lenses, as this can remove factory-applied coatings.

Also, always be sure to rinse them in fresh water after swimming and store them in a protective case to prevent scratches.

If foggy goggles are a persistent problem, investing in a quality pair of anti-fog goggles could be the solution. Many modern goggles come with built-in coatings that help keep them clear for longer.

With these simple tricks, you can keep your goggles fog-free and your swim sessions crystal clear.

Whether you opt for anti-fog sprays, household hacks, or simple splash techniques, there’s a method to suit every swimmer.
