Abstract: The protective eyewear assembly described comprises a frame having right and left portions defining respective right and left apertures and a central bridging portion, and a protective lens piece adapted to be mounted to the lens piece between the upper and lower edges of the frame. The lower edge of the frame has a retaining wall for retaining the lens therein while the upper edges of the frame and the lens piece have cooperating portions to secure the lens to the frame. The frame may be made of flexible plastic material to enable a snap-in engagement and a snap-out disengagement of the lens to and from the frame.

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.

Abstract: Sport eyeglasses having removable lenses formed of a one piece plastic molded frame that includes a pair of lens receiving sections, a pair of opposite strap receiving temple sections and a central bridge section integral with the lens receiving sections are described herein. The bridge section is split to define an upper bridge part and a lower bridge part which are capable of being manually distanced from one another so as to define a gap and allowing lenses to be mounted in the lens receiving sections. A fastening element extends through both bridge parts to secure them together once the lenses are installed in the lens receiving sections.
