ABSTRACT:
Convertible eyewear permits ready conversion between various optical modes. A removable shield is removable secured by magnetic force to a frame by the interaction of at least one magnetic rivet recessed within the frame and at least one magnetic rivet that protrudes from the shield. The mating magnetic rivets may have contacting surfaces of oval shape with the rivet recessed within an oval-shaped channel to prevent misalignment of frame and shield with a single point of magnetic contact. A prescription lens insert and a goggle adapter, each having a protruding magnetic rivet, are compatible for magnetic fixation to the frame of the eyewear.
