Round lenses need consistent curvature all the way around, and the RB4305's 53mm plastic front is cut to hold that shape without the flat spots that show up in poorly matched replacements. Its 145mm temples put it in the mid-range for arm length among Ray-Ban's round styles.

This €25 pair is dimensioned for the RB4305 specifically, not adapted from a nearby size, so the edge sits flush in the frame's channel. It's meant for customers who still like their frame but need clear, unscratched lenses back in it.

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 4305, 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.

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 53mm lens fails to seat correctly or the coating degrades on its own rather than from an impact, we'll replace it free.

Are these genuine Ray-Ban or Oakley lenses?

No — these are aftermarket lenses, independently made to match the 53mm dimensions of the Ray-Ban 4305. They aren't produced or endorsed by Ray-Ban; they're engineered purely to fit that frame correctly.

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

These lenses are cut to the 53mm eye size and Redondo shape of the Ray-Ban 4305, so they seat into your existing frame's groove without trimming, heating, or any modification on your part.
