Fit on the Oakley 4106 Conductor 6 comes down to lens geometry more than the 58mm eye size printed on the frame: these aftermarket lenses are molded to a 38mm height, 63mm diameter, and a Base 6 curve in TAC and polycarbonate, matching the Conductor 6's channel so the edge doesn't lift or gap once it's snapped in.

Base 6 is a tighter wrap than you'll find on flatter Oakley shields, which is why a lens cut to the wrong base curve is obvious the moment it's fitted — even a 58mm lens sits loose if it's built to a shallower curve. Polycarbonate keeps the extra curvature from adding noticeable weight at the temple, and the 63mm diameter leaves enough spare material at the edge for the lens to seat fully before the excess is trimmed to the frame.

Frequently asked questions

What's the warranty if a lens pops out or discolors after a few months?

All lenses are independently made and carry a 3-year warranty against manufacturing defects — if a 58mm lens fails to seat correctly or the coating degrades on its own rather than from an impact, we'll replace it free.

Do replacement lenses block UV rays as well as the ones they're replacing?

Every lens we sell, including each option among the over 15 lens colours, including mirrored and polarized options, blocks 100% of UVA and UVB radiation, so changing the color or finish on your 4106 CONDUCTOR 6 never means sacrificing sun protection.

How much does it cost to replace lenses instead of buying a new pair of sunglasses?

A pair of 58mm lenses for the 4106 CONDUCTOR 6 starts at €26.00, a fraction of a new Oakley frame, and shipping is free worldwide with no minimum order, so the total stays close to that price.

Are these genuine Ray-Ban or Oakley lenses?

No — these are aftermarket lenses, independently made to match the 58mm dimensions of the Oakley 4106 CONDUCTOR 6. They aren't produced or endorsed by Oakley; they're engineered purely to fit that frame correctly.
