Abstract: A contact lens package, comprising blister packaging defining a cavity, a contact lens disposed in an unstressed state within the cavity, lens hydrating liquid partially filling the cavity, and lid stock sealed to the blister packaging such that a segment of the lid stock, in combination with the cavity, forms an enclosure of the lens and the liquid. The segment has an interior surface including at least one relief element. The interior surface exclusive of the at least one relief element is flat. An air gap is disposed between a top surface of the liquid and at least a portion of the interior surface. The at least one relief element on the interior surface of the lid stock may be formed while testing the structure for leaks by applying pressure to the lid stock with a stamp having a contour corresponding to the at least one relief element.

Abstract: A multilayer optical film is disclosed. The multilayer film includes at least two adjacent optically transmissive tacky adhesive layers. Each tacky adhesive layer reflects light by optical interference.

Abstract: An article is disclosed that includes a first substrate, and an adhesive layer disposed between on the first substrate. The adhesive layer includes a first adhesive region having a first adhesive and a second adhesive region having a second adhesive. The first adhesive is different from the second adhesive. The first adhesive region forms indicia. Methods of making and using the article are also disclosed.

Abstract: An article is disclosed that includes a color shifting film having a film surface and an adhesive layer disposed on the color shifting film surface. The adhesive layer includes a first adhesive region having a first colorant and a second adhesive region. Methods of making and using the article are also disclosed.

Abstract: The present disclosure relates to optical bodies including one or more norbornene-based cyclic olefin film layers and one or more rough strippable skin layers operatively connected to a surface of the norbornene-based cyclic olefin film layer. The rough strippable skin layer comprises a continuous phase and a disperse phase. Methods of producing such optical bodies are also disclosed.

Abstract: A laminated optical article comprising at least one optical film bonded with an adhesive composition.

Abstract: The invention relates to an adhesive composition comprising the reaction product of at least one nitrogen-containing polymer and at least one polymerizable ethylenically unsaturated diluent.
