What does low bridge fit mean?

The frame is shaped to sit higher on a flatter or lower nose bridge, so it is less likely to slide down. It suits people who find standard Ray-Ban frames rest too low.

Are the lenses polarized?

No. The dark grey classic lenses reduce brightness but are not polarized, so they do not cut reflected glare from water or roads the way polarized lenses do.

What is the lens size?

The lenses are 50mm wide, a moderate size. On wide faces they can look small, so try them on if you usually wear larger frames.

Can I swap in prescription lenses?

Yes. The full frame takes prescription lenses, and many opticians stock or can cut lenses for this model. Keep the original lenses if you want to switch back.

How does it compare with the standard RB4259?

The F version is the low bridge fit, so the nose pads and frame geometry sit differently. Opt for it if standard frames slide; otherwise the regular fit is the same shape and lens.
