Are the Zaya lenses actually polarized?

Yes. This version ships with polarized gray lenses, which cut glare from water, roads and snow. The non-polarized Zaya looks the same but does not have that glare filter.

Do these work for driving?

Yes. Polarized gray lenses are a good pick for daytime driving because they reduce dashboard and road glare. Very dark tinted windshields or some LCD screens can look odd through polarized lenses.

What face shapes suit the rectangular frame?

The rectangle shape tends to balance round, oval and heart-shaped faces. Square or very narrow faces may find it too wide or too boxy, so try them on if you can.

Is the frame metal or plastic?

It is a molded plastic full frame, not metal. That keeps it light, but it flexes more than Ray-Ban's metal frames and has no spring hinges.

Do the lenses block UV?

Yes. The lenses carry full UV protection, so they shield your eyes from UVA and UVB along with the glare reduction.

How does it compare with the Wayfarer?

The Zaya is a slimmer, more rectangular frame than the chunkier Wayfarer. It suits people who want a Ray-Ban look with a narrower profile and polarized lenses.
