Described herein are various embodiments of eyewear provided for advantageous use in sports and work, as well as in casual activity, and, if desired, in conjunction with helmets or other headgear. According to one exemplary embodiment, eyewear can include a frame and respective spaced-apart temple portions coupled to the frame. Each temple portion can include a proximal portion, a distal portion, and a biasing element that is movable along at least the distal portion in a longitudinal direction of the temple portion. Each biasing element can urge the distal portion of the respective temple portion in a lateral direction, which is generally perpendicular to the longitudinal direction, as the biasing element is moved along the distal portion.
