ABSTRACT:
The lens of a pair of sunglasses may be quickly replaced in its associated frame by inserting the top portion of the lens within an arcuate-shaped recess of the frame and snap fitting a plurality of dowels carried by the frame into corresponding sockets formed in the lens. Notches provided on opposite sides of each dowel facilitate engagement of the dowel within the recess. A V-shaped nose bridge is also secured to a correspondingly shaped notch in the lens and prevented from removal therefrom by a pair of lugs directed inwardly from opposite edges of the notch. A nose support is secured to the bridge by inserting pegs carried by the bridge into homes formed in the support.
