摘要： An optical stack of laminated removable lens for affixing to a face shield is disclosed. The stack includes a plurality of superposed removable lens adhesively affixed to one another, wherein each of the removable lens is held to each successive lens with a clear uninterrupted adhesive layer interposed between each lens. Each of the lens has a removal tab portion on one end which does not have any adhesive layer on either side thereof. This allows the wearer of the face shield to quickly grasp the removal tab portion for removing the top lens and exposing a clean lens directly underneath. The bottom-most removable lens of the stack has a band of adhesive formed around the periphery thereof for attachment of the stack to the face shield. The band of adhesive forms a seal which eliminates any moisture from the interface between the bottom-most lens and the shield.
