An eyeglass for maintaining geometry and optical quality of first and second lenses supported by the eyeglass, the eyeglass comprising: a frame adapted to be carried by the head of a wearer, the frame extending at least partially about a perimeter of the first and second lenses; a first support member pivotably attached to the frame at a first joint such that the first support member can be pivoted relative to the frame between a retaining position and an open position, the first support member being moveable to the retaining position to enclose at least a portion of the perimeter of the first lens for mounting the first lens in the path of the wearer's field of view; a second support member pivotably attached to the frame at a second joint such that the second support member can be pivoted relative to the frame between a retaining position and an open position, the second support member being moveable to the retaining position to enclose at least a portion of the perimeter of the second lens for mounting the second lens in the path of the wearer's field of view; first and second securing members attached to the frame and being configured to move between engaged and disengaged positions for securing the first and second support members relative to the frame, such that the first and second lenses are capable of being secured or unsecured relative to the frame independently of each other when both first and second lenses are mounted in the path of the wearer's field of view, and wherein the first and second securing members are nosepiece components configured to contact the wearer's nose to support the eyeglass.
