RX3447V is the prescription-eyewear version of the round-metal 3447 shape, and it takes the same 145mm metal temple arm as its sunglass counterpart — the spec this compatible pair is cut to. The 'V' in the name marks the optical variant, not a different arm length or hinge position, so fit is identical to the RB3447 despite the different lens type.

Round metal fronts like this one use a narrower hinge plate than square or rectangular frames, which puts the screw under slightly more stress every time the arm is opened. That's usually why the hinge on a round-metal pair loosens before the arm itself shows any bend or wear. A tightened or replaced hinge screw solves a wobble; a cracked or bent arm is what actually calls for swapping the whole temple.

Frequently asked questions

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 3447, mismatches are rare, but you're covered by a 14-day return window if the 145mm arms don't align with your hinge.

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 145mm arm to your 3447 frame — the whole swap usually takes under five minutes.

How do I know these arms will fit my Ray-Ban frame?

These arms are made specifically for the 3447, matching its 145mm length and Redondo hinge design, so they attach to your existing screws and hinge without any filing or adjustment needed.

What material are the arms made from, and will the color match my frame?

The arms are molded in an acetate or metal finish that matches the Redondo style of the 3447 closely, though very slight shade variation is possible since they're independently produced as separate aftermarket parts rather than cut from the same batch as the frame.
