The RX1969V prescription frame uses a rectangular metal front with 140mm arms cut to the same straight-line profile, and this aftermarket pair reproduces that length and shape so the hinge sits flush against the front rather than at a curved angle borrowed from an oval or round style. The 1969 line also exists as the sunglasses-only RB1969, sharing this same rectangular shape, so the RX prefix is the detail that confirms the prescription version specifically.

Rectangular eyeglass frames like the 1969V see constant handling — on and off dozens of times a day — so the hinge screw is usually the first part to work loose, well before the metal arm shows any bend. A quarter-turn tightening every so often, or a fresh arm if the threads have stripped, keeps the fit secure. Checking the hinge every few months is a cheap habit that catches this kind of wear long before the arm itself needs replacing again.

Frequently asked questions

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 Rectangle style of the 1969 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.

My hinge feels loose — will new arms fix that, or is it the frame that's worn?

A new 140mm arm includes its own hinge barrel, so if the wobble is coming from worn threading on the arm side of the 1969, replacing it usually restores a snug, tight fold.

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 140mm arm to your 1969 frame — the whole swap usually takes under five minutes.

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 1969 is broken or scratched, or buy the pair if both need replacing — either way they match the 140mm length exactly.
