The RB3545 pairs a square metal front with a 51mm eye size, so these replacement lenses are cut to that exact width rather than a generic "square metal" spec shared across the range. At 145mm, the temple length also matches this model specifically, keeping the fit snug once the lens clicks back into the frame.

Available in TAC for a lighter everyday tint or polycarbonate for extra impact resistance, both cut to the RB3545's own bevel so the edge sits flush in the metal channel without any filing or adjustment needed.

Frequently asked questions

What if the lenses I order don't actually fit my frame?

Every pair is matched to a specific model, in this case the 3545, so mis-fits are uncommon, but if the lenses don't seat properly you can return them within 14 days for a full refund, no questions asked.

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 3545 never means sacrificing sun protection.

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 51mm lens fails to seat correctly or the coating degrades on its own rather than from an impact, we'll replace it free.

Will these lenses actually fit my exact Ray-Ban or Oakley frame?

These lenses are cut to the 51mm eye size and Square shape of the Ray-Ban 3545, so they seat into your existing frame's groove without trimming, heating, or any modification on your part.
