ABSTRACT:
The eyewear described comprises a lens having, at opposite lateral sides thereof, a pair of detachable ear stems which are adapted to move from an inwardly folded position to an outwardly ear contacting position. The lens displays, at each lateral side, an opening and a stem connecting portion that defines a hinge element forming an integral part of the lens. The proximal end portion of the ear stem defines a U-shaped recess which is engageable with the hinge element. The recess is formed by a pair of resilient branches which, together with a constriction at the entry of the recess, enables a snap-in engagement and a snap-out disengagement of the ear stem to and from the lens. No additional component is required for this three-piece eyewear.
