1. A protective eyewear lens assembly comprising:
a lens body at least partially formed from a first quantity of polymeric material, said lens body having a lens height, a lens width and a lens thickness, said lens body extending in a widthwise direction between a first lens end and a second lens end opposite said first lens end, said lens body extending in a heightwise direction between a first edge surface portion and a second edge surface portion spaced apart from said first edge surface portion, said lens body including a first side surface portion and a second side surface portion facing opposite said first side surface portion such that said lens thickness is at least partially defined therebetween, said lens body including a first hinge connection disposed along said first lens end, a second hinge connection disposed along said second lens end, a first optically-transparent portion disposed toward said first lens end, a second optically-transparent portion disposed toward said second lens end with said first and second hinge connections and said first and second optically-transparent portions unitarily formed from said first quantity of polymeric material, and an elongated groove extending widthwise across said lens body, said elongated groove extending into said lens body in said thickness direction from an open end along said first side surface portion toward a groove face surface offset in said thickness direction from said first and said second side surface portions such that said groove face surface is disposed therebetween;
a metal-detectable component formed from an elongated length of metal-detectable material and extending lengthwise between first and second component ends, said metal-detectable component at least partially disposed within said elongated groove of said lens body; and,
an elongated cover body at least partially formed from a second quantity of polymeric material that is separate from said first quantity of polymeric material, said elongated cover body extending across and along said elongated groove, said elongated cover body at least partially disposed within said open end of said elongated groove and permanently attached to said lens body such that said metal-detectable component is permanently encased within said elongated groove by said elongated cover body.
