PREMIUM ANTI-FOG is a high-performance anti-fog technology developed by SWANS.
Features of PREMIUM ANTI-FOG
・Enhanced Absorption Compared to Conventional Products
PREMIUM ANTI-FOG provides improved absorption of moisture, the main cause of fogging. This helps maintain a clear view for a longer time.
・Supports Extended Use
Its long-lasting anti-fog performance allows swimmers to maintain clear vision during training and competitions, helping them stay focused.
・Proven Effectiveness Through Real-Use Testing
The product underwent approximately one year of testing in real swimming environments to confirm its effectiveness.
Comparison with Conventional Anti-Fog Coated Lenses
PREMIUM ANTI-FOG lenses quickly absorb sudden moisture (such as steam or humidity), continuously maintaining a clear field of vision.
Feedback from Monitors
*We conducted a one-month monitoring test with general users.
Male in his 60s / 55 years of swimming experience
“My underwater vision is bright and clear. I don’t notice any fog. Even during body temperature changes before and after a race, the fog was minimal. I could clearly see underwater without using any anti-fog solution. Very comfortable.”
Female in her 50s / 6 years of swimming experience
“This is the first pair of goggles that didn’t fog up without applying any anti-fog. Even after wearing them for a long time, I experienced no fog blocking my vision.”
Male in his 70s / 15 years of swimming experience
“I’ve tried many brands, but PREMIUM ANTI-FOG was the first that I could use without worrying about fog from the start. I’m curious to see how long this effect lasts.”
Female in her 30s / 6 years of swimming experience
“They hardly fog up. I’m still using them without any anti-fog solution—just rinse with pool water, and that’s enough.”
Male in his 40s / 35 years of swimming experience
“I’ve always used SWANS goggles with cushions, so these felt familiar. It’s reassuring not needing anti-fog solution. Even when wearing the goggles under my swim cap during competitions, I had no concerns.”
Female in her 60s / 13 years of swimming experience
“The visibility is incredibly clear. My previous goggles needed anti-fog solution after just two weeks.”
How Anti-Fogging Works
The anti-fog mechanism works by forming a thin layer of water on the inside of the goggle lens, which absorbs moisture and vapor from the eyes and skin, preventing fog from forming. Products marked with the PREMIUM ANTI-FOG logo provide significantly higher anti-fog performance compared to conventional anti-fog coated goggles.
To maintain this effect, it's important to rinse the inside of the lenses with water before and after use.
Usage Tips for Long-Lasting Anti-Fog Performance
Correct Usage for Maintaining Anti-Fog Performance Over Time
・Before Swimming
Wet the inside of the lenses thoroughly with water to activate the anti-fog effect before use.
・If Fogging Occurs During Swimming
Simply re-wet the inside of the lenses with water.
After Swimming
Rinse with tap water, shake off excess water, and air dry in the shade.
Important notes
The inner surface of PREMIUM ANTI-FOG lenses is specially treated.
Do not touch the inner lens surface when dry or wet.
Touching it with fingers or a towel may scratch the surface and reduce anti-fog performance.
