Anti-fog and swimming goggles - what is it and how does it work?

Anti-fog and swimming goggles - what is it and how does it work?

Few things are more frustrating for swimmers than foggy goggles. Whether you're a competitive swimmer, a triathlete, or just enjoying a recreational swim, blurred vision caused by fog buildup can disrupt your performance and break your focus.

Here at SWANS we pride ourselves in our anti-fog technology enabling our swimmers to swim clearly.

 

How Anti-Fog Works

Anti-fog goggles are treated with a special coating on the inside of the lenses that helps prevent condensation from forming. This coating works by reducing surface tension on the lens, spreading water droplets into a thin, even layer, making them less noticeable. This results in clearer vision and helps swimmers maintain focus without the constant need to adjust or clean their goggles.

While many goggles come with built-in anti-fog coatings, it’s essential to handle them with care. 

Choosing the Right Anti-Fog Goggles

When shopping for swim goggles with anti-fog technology, consider the following factors to ensure you’re getting a pair that suits your needs:

  1. Built-In Anti-Fog Coating: Many high-quality goggles come pre-treated with a durable anti-fog coating. Look for goggles that mention “anti-fog” on the packaging or product description.

  2. Lens Type: The environment you’re swimming in should influence your choice of lenses. For outdoor swimming, mirrored or polarized lenses with UV protection can block glare and sunlight while still offering anti-fog benefits. For indoor pools or low-light conditions, clear lenses with anti-fog technology work best.

  3. Durability: If you’re a frequent swimmer, durability is essential. Opt for goggles with scratch-resistant lenses and sturdy silicone seals that can endure regular exposure to chlorine and sun without breaking down.

  4. Comfort and Fit: Comfort is key to preventing distractions in the water. Make sure the goggles you choose have a comfortable, leak-proof seal and can be adjusted to fit your face properly. Adjustable straps and interchangeable nose pieces can help create a better fit.

Maintaining Your Anti-Fog Goggles

Once you’ve invested in a good pair of anti-fog goggles, maintaining them properly will extend their lifespan and keep the anti-fog treatment effective. Here’s how to care for them:

  • Rinse After Each Use: Rinse your goggles with fresh water after every swim session to wash off chlorine, saltwater, and dirt that could damage the anti-fog coating.
  • Air Dry: Let your goggles air dry naturally in a cool, dry place. Avoid wiping them with towels, as this can scratch the lenses or degrade the coating.
  • Store in a Case: Store your goggles in a protective case to keep them safe from scratches, dust, and other potential damage. Keeping them away from direct sunlight and extreme heat will help maintain the integrity of the anti-fog coating.

Foggy goggles don’t have to be a recurring frustration for swimmers. By investing in quality anti-fog swim goggles and following simple maintenance tips, you can ensure a clearer, more enjoyable swim experience. Whether you're training for a race, practicing in open water, or swimming laps at your local pool, keeping your goggles fog-free allows you to focus on what really matters—your performance in the water.
