Before you choose

Find the right lens size for your RB3734

The inscription on the inside of the arm lets you confirm the model and exact lens measurement without visually comparing frames.

Inscription on the inside of the arm: RB3734 ··· 56□·· ···Example for guidance only. The position and order of the codes may vary depending on the frame.

How to read the inscription

In an inscription such as RB3734 ··· 56□·· ···, each part has a purpose:

RB3734ModelMust match this product.
···Frame colorIdentifies the finish of the frame front.
56Lens sizeThis is the size you need to select.
··BridgeThis is not the lens size.

This reference comes in 2 sizes. Find the number right before the □ symbol on your arm and choose that same lens size:

  • 56□ → 56 mm
  • 59□ → 59 mm

The number after the □ is the bridge: it isn't used to choose the lens. Can't read it? Measure your lens from side to side at its widest point; that measurement in millimeters matches the lens size.
