Why do my swimming goggles fog up?
Fogging is mainly due to the temperature difference between the body and the water.
As the body is warmer than the practice environment, fogging occurs on the inside of the lenses through evaporation.
As a result, every micro-drop of perspiration will stick to the inside of the goggles.
In fact, it's a bit of luck: all these drops will eventually combine to create a film of water through which you can see clearly.
The anti-fog treatment
The anti-fog treatment creates a microscopic film of water to allow clear vision, but its wear is accelerated by rubbing inside the lenses or over-exposure to chlorinated water. Taking care of the inside of your glasses is essential.
Over time, it is normal for the anti-fog effect to diminish. Briefly soaking the glasses in water may help in the short term, but can also accelerate the wear of the treatment. Our anti-fog marker reactivates the treatment!
Size: how to choose your swimming goggles
Available in size S (children and small heads) and size L (large heads).
The watertightness of the glasses depends on the fit of the silicone skirts to the shape of the face.
Before buying your glasses, we recommend that you carry out the "suction cup" test without the elastic band. Position the goggles over your eyes; if they hold on by themselves with a little suction, they will be watertight once in the water. This test can also identify areas of discomfort or annoyance on the face.
How to adjust your swimming goggles
These swimming goggles fit the morphology of your face without needing to be overly adjusted.
Goggles that are too tight can cause discomfort, leave marks and even create water inlet holes.
It is not necessary to press against the lenses with your hands, a light suction effect is usually enough for swimming sessions without water inlet holes.
The straps ideally should rest 2-3Â cm above your ears.
This position will optimise the grip and comfort of the goggles.
UV PROTECTION
Complies with standard: Q/BT 4734 -2023, all Nabaiji swimming goggles protect against harmful UVA and UVB rays when used normally, regardless of the lens tint.
Looking directly at the sun is dangerous and can lead to irreversible eye damage.
CARE - PRECAUTIONS
- Rinsing your goggles (only if necessary) by simply dipping them in water
- avoiding directing powerful jets of water at the inner surface of the lenses.
- Storing the goggles in their case after each session to prevent damage to the lenses (on the inner surface to preserve the anti-fog coating and on the outer surface to prevent scratches)
- Not exposing them to temperatures of over 60°C
Finally, do not touch / rub the inside of your lenses
