Speedo BIOFUSE 2.0 swimming goggles including prescription lenses

Hello Rosemary
The Eagle goggle is sorely missed but hopefully will be back next year.
Water has a different refractive index to air, so if the front surface of the lens is not flat, the effective power under the water will be slightly different than it is over.

For most people this does not matter as the purpose of the goggles is to generally see better, find the right changing rooms and family or friends at the pool or beach. However, for those that need to see well under water, for spot turns etc., this can matter.

Some swimming goggles have flat fronted lenses, some a slight or moderate curvature. This varies by brand and model.
If you wish to double check we have listed the approximate base curve for each model (e.g. Flat lenses (base curve ≈0) or Curved lenses (base curve ≥4) in the ‘Product Information’ section.
The Biofuse has curved lenses (base curve ≥4), the Eagle has flat lenses (base curve ≈0).

Hello Sam

I am sorry to read that the Speedo Biofuse goggles were not a perfect fit for you.
I can see that you have previously ordered the Coral, buying 3 pairs since May 2025.

If you do decide to re-order a new goggle, try them on first at home as face, nose and eye socket shapes do vary between swimmers.
We have written a short guide to help with fitting to prevent leaks by checking for lens suction against the eye sockets;

I would suggest trying another goggle with an adjustable nosebridge or with interchangeable bridges (as in the Coral) as they include small, medium & large.
