A patented innovation
If you're looking for swimming goggles that fit your face perfectly, are completely waterproof and won't move when you dive or tumble, then
is the answer with B-FAST goggles, featuring a simple, micrometric nose bridge adjustment system. This system allows you to precisely adjust the distance between the two lenses, using a screwdriver (supplied with the goggles) or the tool built into the rear buckle.
FINA APPROVED
B-FAST goggles are FINA (Fédération Internationale de Natation) approved training and competition goggles.
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 micrometric nose bridge adjustment.
The waterproofness 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 smoked goggles to limit glare, for greater comfort vision .
If, on the contrary, the pool is rather dark with low luminosity, in the evening in winter for example, prefer clear lenses.
B-FAST swimming goggles are available in different lens tints.
Protection
In compliance with the QB/T 4734-2023 standard, all Nabaiji swimming goggles protect against harmful UVA and UVB rays under 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.
