Abstract: Described herein are various embodiments of eyewear provided for advantageous use in sports and work, as well as in casual activity. According to one embodiment, an eyeglass can include a frame and an eyecup assembly coupled to the frame. The eyecup assembly can include a resilient side member that has a first proximal portion that is fixed relative to the frame and a second distal portion that is movable relative to the frame and biased toward the frame. The eyecup assembly can also include an adjustment mechanism that is coupled to the resilient side member and positioned at least partially between the resilient side member and the frame. The adjustment mechanism can be selectively operable to flex the resilient side member to move the second distal portion away from the frame and to un-flex the resilient side member to move the second distal portion toward the frame.

Abstract: 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.
