Why do my swimming goggles fog up?
The main cause of fogging is the difference in temperature between your body and the water.
As your body is warmer than the water, fogging occurs inside your goggles through evaporation.
As a result, each micro-drop of perspiration will stick to the inside of your goggles.
In fact, it's a stroke of luck: all these drops will eventually combine to create a film of water through which you'll be able to see clearly.
Anti-fogging treatment
The anti-fog coating 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 lenses is essential.
Over time, it is normal for the anti-fog properties to diminish. Tempering glasses briefly in water may help in the short term, but it also accelerates the wear and tear of the treatment. Our anti-fog marker allows you to reactivate the treatment!
Size: how to choose your swimming goggles?
One-size-fits-all model with 3 interchangeable nose bridges.
The watertightness of the goggles depends on the fit of the silicone skirts to the shape of the face.
Before buying your goggles, we recommend you perform the "suction cup" test without the elastic band. Place the goggles on your eyes, and if they hold on by themselves with a slight suction, then they'll be watertight once in the water. This test can also be used to identify areas of discomfort or discomfort on the face.
How do I adjust my goggles?
Swimming goggles that are adapted to your facial morphology don't require much adjustment.
Goggles that are too tight can cause discomfort, marks and sometimes even water ingress.
It's not necessary to press on the lenses with your hands; a slight suction cup effect is often sufficient for swimming sessions without water ingress.
The straps ideally pass 2 to 3cm above the ears.
This position will optimize the fit and comfort of the goggles.
Lens tinting
The tint of your lenses must be adapted to your practice area and its luminosity.
If you practice outdoors or in a pool with strong luminosity, choose goggles with smoked lenses to limit glare.
If, on the contrary, the pool is rather dark with low luminosity, in the evening in winter for example, prefer clear lenses.
BFIT swimming goggles are available in different lens tints.
UV protection
In compliance with the QB/T 4734-2023 standard, all our swimming goggles protect against harmful UVA and UVB rays during normal use, regardless of lens tint.
Direct observation of the sun is dangerous and can lead to irreversible eye damage.
MAINTENANCE - PRECAUTIONS
- Rinse your glasses (only if necessary) by simply soaking them in water
- Avoid powerful jets of water directly on the inside of the lenses.
- Store your glasses in their box between each session to avoid damaging the lenses (on the inside to preserve the Anti-fog treatment, on the outside to avoid scratches)
- Avoid exposure to temperatures above 60°c
And finally, do not rub or touch the inside of your lenses.
