An eyewear article (100, 200), comprising: a temple piece (110, 210) extending rearwardly from a front of an eyewear article having a flexing portion (120, 220) having a maximum height in a direction parallel to a mid-sagittal plane, the mid-sagittal plane bisecting the eyewear article into imaginary left and right halves; wherein the flexing portion comprises first and second longitudinally disposed ribs (125,126; 225,225), each rib having first and second major surfaces (S1 and S2) separated by a thickness (t), and including a length (l) in the longitudinal direction of the rib, and a height (h) in a direction perpendicular to each of thickness and length, wherein when the temple piece is in an unflexed state the first rib is angularly disposed with respect to the second rib, such that the first and/or the second major surface of the first rib form(s) an angle with the first and/or the second major surface of the second rib, respectively, that is not within 5° of 180° and such that one or both of the first and second major surfaces of the first and second ribs are not within 5° of forming a 90° angle with a transverse plane of the eyewear article, said transverse plane bisecting the eyewear article horizontally into imaginary upper and lower portions, and H > 20 mm; wherein when the temple piece is flexed, such that the eyewear article is positioned for use on a head of a user, the first and second ribs rotate such that said one or both of first and second major surfaces of the first and second ribs are closer to being perpendicular to the transverse plane; wherein the curvature of a flexing portion is greater in an unflexed state than when the eyewear is positioned for use on the head of a user; and wherein the temple piece is rotatably secured to an attachment portion of the eyewear article with a hinge that permits pivotal motion of the temple piece between an open and a closed position. wherein the flexing portion comprises first and second longitudinally disposed ribs (125,126; 225,225), each rib having first and second major surfaces (S1 and S2) separated by a thickness (t), and including a length (l) in the longitudinal direction of the rib, and a height (h) in a direction perpendicular to each of thickness and length, wherein when the temple piece is in an unflexed state the first rib is angularly disposed with respect to the second rib, such that the first and/or the second major surface of the first rib form(s) an angle with the first and/or the second major surface of the second rib, respectively, that is not within 5° of 180° and such that one or both of the first and second major surfaces of the first and second ribs are not within 5° of forming a 90° angle with a transverse plane of the eyewear article, said transverse plane bisecting the eyewear article horizontally into imaginary upper and lower portions, and H > 20 mm; wherein when the temple piece is flexed, such that the eyewear article is positioned for use on a head of a user, the first and second ribs rotate such that said one or both of first and second major surfaces of the first and second ribs are closer to being perpendicular to the transverse plane; wherein the curvature of a flexing portion is greater in an unflexed state than when the eyewear is positioned for use on the head of a user; and wherein the temple piece is rotatably secured to an attachment portion of the eyewear article with a hinge that permits pivotal motion of the temple piece between an open and a closed position.
