At 61mm, the RB3528 carries one of the largest lens openings in this lineup, and it's set into a metal round frame rather than plastic, which changes how the edge is beveled to seat in the rim. The 145mm temples are mid-length for the style.

This €25 set is cut to the RB3528's 61mm metal-frame curve specifically, since a lens sized for a smaller round opening won't seat flush in a rim this large. It's built to replace scratched or clouded lenses without altering the frame itself.

Frequently asked questions

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 3528 never means sacrificing sun protection.

How hard is it to install replacement lenses myself?

Most Redondo frames use a simple press-fit: flex the frame slightly, seat one edge of the 61mm lens into the groove, then work your thumb around the rim until it clicks into place — no tools needed.

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

These lenses are cut to the 61mm eye size and Redondo shape of the Ray-Ban 3528, so they seat into your existing frame's groove without trimming, heating, or any modification on your part.

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 61mm lens fails to seat correctly or the coating degrades on its own rather than from an impact, we'll replace it free.
