RX6589 Aviator Gaze is a prescription take on the classic aviator shape, with an all-metal front and 140mm arms curved to the aviator profile. This aftermarket pair keeps that same curve and length, so the temple meets the front the way it does on the factory pair, rather than the straighter arm used on Ray-Ban's rectangular eyeglass lines. Matching the curve matters more here than the length alone, since a straighter substitute would visibly clash with the aviator front.

Aviator-shaped eyeglass frames put more of the visual weight on the arm than square styles do, since the curve is part of the overall look, not just a functional bend. If the arm has lost its curve or the metal has discolored at the hinge, replacing it restores the silhouette without touching the lenses or the front. Checking both arms match once fitted is worth the extra step, since an uneven curve is more noticeable on this shape than on a boxier one.
