4. Aqua Sphere Kayenne Small Fit
The draw: Narrow fit, wide view
With a 20 percent smaller fit than the original, this version of the Kayenne is perfect for swimmers with a narrower face shape. The frame is low-profile (one tester mentioned the lenses felt close to her eyelashes), comfortable and sleek, with a unique lens shape that allows for 180-degree visibility. A button on the side of the lens makes strap adjustment easy.
