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.
How to activate the anti-fog of your swimming goggles?
Activate anti-fog by immersing the goggles in water and then running your finger along the inside of the lenses (do not immerse the goggles in water again).
In the event of recurrent fogging (every 40 sessions on average), clean the inside of the goggles with neutral, liquid soap (avoid solid soap), to remove the layer of pollution that has settled on them.
Don’t worry about scratches, this new technology is highly resistant to abrasion.
How do these anti-fog goggles work?
Soaking the goggles, then running your finger inside them, creates a film of water that protects you from fogging up throughout your training.
Fog no longer settles on the surface of the lenses because it is absorbed by this film of water.
The vision through the film of water is clear, so you can enjoy your session to the full.
If you take off your goggles and put them on your forehead, you may lose the water film: you then have to run your finger inside again to reform it.
Size: how to choose your swimming goggles
One-size model with precise nose bridge adjustment.
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 2-3 cm above your ears.
This position will optimise the grip and comfort of the goggles.
Lens tint
The colour of your goggles should be suited to your swimming location and its lighting.
If you practice outside or in a pool with harsh lighting, prioritise goggles with smoky lenses to limit the glare for greater comfort.
If, however, the pool is quite dark with low lighting, winter evenings for example, use clear lenses.
The B-FAST swimming goggles are available in different lens tints.
Protection
Complies with standard: Q/BT 4734 -2023, all our 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.
