Abstract: A snap-on construction for sunglasses of the type used with wire frame spectacles having a reinforcing wire or bar extending from the upper edge of one spectacle lens to the upper edge of the other lens. The sunglasses include a support frame member to which the pair of lenses are secured at least at an upper portion thereof and a pair of spaced posts extend rearwardly from the support frame. Each post includes a slot opening into the rear end thereof for receiving the reinforcing bar of the wire frames, and a locking bar selectively snaps into the slots behind the reinforcing bar to retain the sunglasses assembled on the spectacles.
