Metal frames like the RB4228 hold their lens channel more rigidly than plastic, which means the 58mm square lenses need to be cut to a tighter tolerance to seat cleanly. Its 140mm temples are standard length for a square metal build in this range.

This €25 replacement pair matches the RB4228's 58-140 metal-frame spec, so the lenses lock into the existing rim without needing to be reshaped or forced. It's built for the frame's square geometry, not a generic round-to-square approximation.

Frequently asked questions

Can I get polarized or mirrored lenses instead of the flat tint that came with my sunglasses?

Yes. Beyond the standard tint, we stock over 15 lens colours, including mirrored and polarized options for the 4228, so you can upgrade to polarized or mirrored glass in the same 58mm size your Ray-Ban frame already takes.

How hard is it to install replacement lenses myself?

Most Square frames use a simple press-fit: flex the frame slightly, seat one edge of the 58mm lens into the groove, then work your thumb around the rim until it clicks into place — no tools needed.

Are these genuine Ray-Ban or Oakley lenses?

No — these are aftermarket lenses, independently made to match the 58mm dimensions of the Ray-Ban 4228. They aren't produced or endorsed by Ray-Ban; they're engineered purely to fit that frame correctly.

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

Every pair is matched to a specific model, in this case the 4228, 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.
