During swimming, heat and moisture from your face build up inside the goggles. When this warm, humid air comes into contact with a cooler lens, the moisture turns into tiny droplets that scatter light and reduce visibility.

Fogging is more likely during longer swims, in colder water, or when goggles are taken off and put back on multiple times. Temperature differences between your face, the water, and the surrounding air all play a role.

Kyrox FogShield+™ is a permanent hydrophilic lens technology built directly into the goggle lens to manage condensation during swimming.

Instead of allowing moisture to form visible droplets that blur vision, FogShield+™ spreads moisture evenly across the lens surface. This creates a thin, transparent moisture layer that stays clear while you swim.

Because FogShield+™ is integrated into the lens itself and not a spray or temporary coating, it does not wash off and is designed to perform consistently over repeated swims in both pool and open-water conditions.

Before swimming, lightly wet the inside of the lens and gently wipe it with your fingertip a few times. This helps activate the hydrophilic surface so it can manage moisture effectively during your swim.

After wiping, rinse the lens with water and put the goggles on.

Kyrox does not rely on anti-fog sprays because they treat the symptom rather than the cause. Sprays add a temporary layer that wears off over time.

Instead, Kyrox goggles use FogShield+™ lens technology, which is integrated directly into the lens and designed to manage condensation consistently over repeated swims.

Regular swim goggle lenses use a thin anti-fog coating applied to the inside of the lens. Touching or rubbing this coating reduces its effectiveness over time, which is why swimmers are advised not to touch the lens interior.

Kyrox FogShield+™ uses a permanent hydrophilic technology integrated into the lens itself. Because the anti-fog function is not a surface coating, the lens can be wiped with water without damaging performance, helping maintain consistent clarity over repeated swims.

The goggles should sit naturally around your eyes and create a stable seal without excessive strap tightening. If the goggles feel tight, pinch, or leave deep marks, the fit is likely incorrect.

Kyrox goggles include multiple nose bridge sizes (S, M, and L). Choosing the correct nose bridge helps position the lenses properly, improving comfort and reducing leaks. In most cases, adjusting the nose bridge provides a better fit than tightening the strap.

The best lens color depends on where and when you swim.

Clear lenses: Ideal for indoor pools and low-light conditions

Smoke lenses: Lightly tinted and designed to work well in both indoor and outdoor environments, making them a highly versatile all-round option

Mirrored lenses: Designed for strong sunlight and open-water glare

If you swim both indoors and outdoors, a smoke lens offers the most versatility.

Yes. Triathletes need no leaks, clear vision, a wide field of view, and easy adjustment. Kyrox swim goggles are designed to meet these demands. By focusing on stable sealing, consistent visibility, and practical usability, Kyrox helps triathletes stay focused from the start of the swim through to transition.

Yes. Open-water swimming involves waves, changing light conditions, and longer continuous distances.

Kyrox swim goggles are designed for these challenges. Extra-soft TPE eye cups help create a leak-resistant seal, while FogShield+™ lenses manage condensation during longer swims. The lenses also offer UV protection and glare-reducing options to support visibility as conditions change.

Rinse your goggles with fresh water after each swim to remove chlorine, salt, and debris. Store them in a cool, dry place away from direct sunlight. Never use harsh chemicals or abrasive materials to clean them.
