For €25, this replacement lens set covers the RB3610's 58mm square opening - the same eye size as several of Ray-Ban's round plastic models, but cut to a squared curve instead, since the metal frame's rim geometry is completely different.

The 140mm temples on the RB3610 are standard length for a square metal build, and the lenses here are sized to match that specific rim rather than a generic square template. It's a direct fit for customers who want their existing frame back in working order without buying new hardware.

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 3610 never means sacrificing sun protection.

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.

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

These lenses are cut to the 58mm eye size and Square shape of the Ray-Ban 3610, so they seat into your existing frame's groove without trimming, heating, or any modification on your part.

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 3610, so you can upgrade to polarized or mirrored glass in the same 58mm size your Ray-Ban frame already takes.
