Abstract
Protective eyewear lens assemblies include one or more metal-detectable components and a lens body. The lens body is formed from a polymeric material and the one or more metal-detectable component are permanently encapsulated on, along or within the lens body. Protective eyewear including such lens assemblies and methods of manufacture are also included.
Claims20
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 width and extending widthwise between a first end and a second end opposite said first end, said lens body including a first optically-transparent portion disposed toward said first end, a second optically-transparent portion disposed toward said second end, a first hinge connection disposed along said first end and a second hinge connection disposed along said second end with said first and second optically-transparent portions and said first and second hinge connections unitarily formed from said first quantity of polymeric material, and said lens body including an outer peripheral edge with an elongated groove extending into said lens body along said outer peripheral edge;
- a metal-detectable component formed from an elongated length of metal-detectable material and extending lengthwise between first and second component ends disposed within said elongated groove of said lens body;
- and,
- an elongated cover wall formed from a second quantity of polymeric material that is separate from said first quantity of polymeric material, said elongated cover wall disposed within and extending along said elongated groove, said elongated cover wall permanently attached to said lens body such that said metal-detectable component is permanently and substantially-entirely encased in said lens body within said elongated groove by said elongated cover wall.

A protective eyewear assembly comprising:
- a lens assembly including:
- a lens body at least partially formed from a first quantity of polymeric material, said lens body having a body width, a body height and a body thickness, said lens body extending in a widthwise direction between a first body end and a second body end opposite said first body end, said lens body including a first body side surface dimensioned to face toward an associated wearer and a second body side surface portion facing opposite said first side surface portion such that said body thickness is defined therebetween, said lens body including first and second hinge connections with said first hinge connection disposed along said first body end and said second hinge connection disposed along said second body end, a first optically-transparent portion disposed toward said first body end, a second optically-transparent portion disposed toward said second body end and a bridge portion disposed between and operatively interconnecting said first and second optically-transparent portions, and with said first hinge connection, said second hinge connection, said first and second optically-transparent portions and said bridge portion unitarily formed from said first polymeric material, and said lens body including an outer peripheral edge with an elongated groove extending into said lens body along at least a portion of said outer peripheral edge;
- a metal-detectable component formed from an elongated length of metal-detectable material and extending lengthwise between first and second component ends;
- and,
- an elongated cover wall formed from a second quantity of polymeric material that is separate from said first quantity of polymeric material, said elongated cover wall disposed within and extending along said elongated groove in said widthwise direction of said lens body, said elongated cover wall permanently attached to said lens body such that said metal-detectable component is permanently and substantially-entirely encased along said lens body by said elongated cover wall;
- a first temple pivotally attached to said first hinge connection of said lens body;
- and,
- a second temple pivotally attached to said second hinge connection of said lens body.
