Swimming Goggles

The inside of the swimming goggles was already broken, I think some kind of film is now worn out. I didn’t know that this will happen too fast, it was just used for a couple of times for swimming classes, I hope to use it soon, but when I checked it, it’s already broken. Due to this, the vision is now blurred which makes it hard to see.

Nabaiji swim goggles 500b-fit smoke lenses

There is a blueish coating on the inside of the lense which when wiped comes off bit by bit. My son wore them at swimming class and when they fogged up in swim class his swim teacher asked him to wipe them with his hand. He did and that’s when the coating started to come off. The lenses also mark easy. We paid more for them because the cheaper ones were also bad quality. Thinking the dearer ones would be better.

Poor Quality Lens

Inside of lens scratches easily, and film is not sealed properly.

Dear Kelvin,

Thank you for your feedback. We are sorry to hear that you have discover any issues with this model of goggles. We understand that you had some scratches inside the goggles? If you purchased them in the store then probably you took the display one instead of brand new pair. We will be very happy to exchange for new pair and we hope this time you won't have any issues.

Once again apologies for any inconvenience caused.

Additional Product Information



  • 100% Polycarbonate


  • 100% Styrene ethylene butadiene styrene


  • 100% Silicone


  • 100% Polycarbonate


  • 100% Polypropylene


The appearance of fog depends on several factors, the difference in temperature between the body and the water, humidity levels, etc. Wear due to friction is one of the main causes. If your goggles fog up, dip your lenses in the water and a protective film will re-form. After a certain amount of time it is normal for the performance of the anti-fog coating to be diminished. We offer an anti-fog marker that reactivates an aging anti-fog treatment and makes your goggles last longer.

Choice of size

The watertightness of the swimming goggles is dependent on the proper fit of the skirts with the shape of your face. Before purchase, we advise you to do the "suction" test without the strap. If the goggles stay on the face by themselves via slight suction, the product will be watertight during your swim. This also enables you to spot any areas of discomfort or annoyance when the model is on the face. 1-size model with 3 interchangeable nose bridges

How to adjust your goggles

These swimming goggles mold to the morphology of your face without needing to be excessively tight. 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 0.8" to 1.2" above your ears. This position will optimize the grip and comfort of the goggles.

Care - precautions

We recommend: - 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 as there is an anti-fog coating and on the outer surface to prevent scratches) - not exposing them to temperatures of over 140°F DO NOT TOUCH/RUB THE INSIDE OF YOUR LENSES

Lens tint

The color of your goggles should be suited to your swimming location and its lighting. If you swim outside or in a swimming pool with bright lighting, prioritize smoke lenses for greater comfort and to limit the glare. If, however, the pool is quite dark with low lighting, winter evenings for example, use clear lenses. The BFIT swimming goggles are available in different lens tints.

Uv protection

Complies with standard: Q/BT 4734 - 2014, all the 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.



Product testing

The Nabaiji swimming goggles comply with the EPI regulation 2016/425. Our products are tested and approved by independent laboratories. Goggles intended for swimming at the surface

Storage instructions

After use, store the goggles in their case. Important: Do not touch the inner surface of the lenses as this could destroy the anti-fog treatment
