RX6389 The General is one of Ray-Ban's prescription optical frames, and this aftermarket arm is made specifically for that model code rather than adapted from a similar-looking style elsewhere in the range. Ordering by the RX6389 code, rather than by a description of the shape alone, is what keeps the hinge and the fit consistent with the frame's factory temple, especially since Ray-Ban has used the General name across more than one related frame over the years.

Prescription frames like this one tend to need a replacement arm long before the lenses need updating, since the hinge is the part that sees daily flex from being taken on and off. If the front and lenses are still in good condition, a matched replacement arm is the more practical fix than buying a new frame outright. Keeping the old arm to compare against the replacement, even a broken one, is a useful way to confirm the fit before considering the swap complete.

Frequently asked questions

Can I replace just one arm, or do I have to buy both?

You can order a single side if only one arm on your 6389 is broken or scratched, or buy the pair if both need replacing — either way they match the mm length exactly.

What if the arms arrive and the hinge doesn't line up with my frame?

Because each pair is listed against a specific model, in this case the 6389, mismatches are rare, but you're covered by a 14-day return window if the mm arms don't align with your hinge.

Is it worth buying new arms instead of a whole new frame?

Replacing both arms on the 6389 costs from €26.95 with free worldwide shipping, far less than a new frame, and it's backed by a 3-year warranty against manufacturing defects on the mm hardware itself.

Do I need a specific screwdriver to attach these myself?

You'll need a small eyeglass screwdriver, typically included in basic repair kits, to remove the old hinge screw and attach the new mm arm to your 6389 frame — the whole swap usually takes under five minutes.
