Our take on the Ray-Ban Kai Bio-based Sunglasses

The Ray-Ban Kai is a metal-frame sunglass with an oval lens shape and a bio-based build. It uses adjustable nose pads and solid-tint lenses, and it is made in Italy. The oval metal look sits apart from Ray-Ban's thicker acetate frames like the Wayfarer, so it suits people who want something lighter and more retro. Owners rate it very highly, and the main notes are the slim metal build and the fit adjustments the nose pads allow.

Best forShoppers who want a slim metal frame instead of thick acetatePeople drawn to oval, retro-shaped lensesWearers who need to fine-tune the fit at the noseEveryday wear with a light, low-profile frame
Pros
  • Oval metal frame with a light, slim profile

  • Bio-based construction in the frame materials
  • Made in Italy
Cons

Questions and answers

How does the Kai compare with the Ray-Ban Wayfarer?
The Kai is a slim oval metal frame, while the Wayfarer is a thicker acetate frame with a squarer shape. The Kai is lighter and more retro; the Wayfarer is bolder and more substantial.
Are the nose pads adjustable?
Yes. The Kai has adjustable nose pads, so you can shift the frame to sit evenly on your nose.
What does bio-based mean here?
Ray-Ban uses bio-based materials in the frame rather than only standard petroleum-based plastics. The lenses are solid tint, not polarized.

Oval frames tend to flatter angular and square faces by softening the lines. Try them on if you can, since the slim shape is a matter of taste.

The Kai is made in Italy.
