Abstract
An eyewear assembly includes an outer first frame, at least one outer first lens, an inner second frame, and at least one inner second lens. The assembly includes a mechanism for holding the first frame and first lens in front of a user's face. The second frame has a mechanism for attachment to the first frame, to hold the second frame between the user's eyes and the first lens. The at least one second lens is carried by the second frame. The second frame includes a first frame portion that mounts the second lens and a second frame portion overmolded onto the first frame portion defining portions of the outside surface area of the second frame. The first frame portion is of a relatively hard material and the second frame portion is of a relatively soft material. A shock-absorbing pad can be fit between the first and second frames.
