Abstract: A photochromic polyurethane laminate that is constructed to solve certain manufacturing difficulties involved in the production of plastic photochromic lenses is disclosed. The photochromic laminate includes at least two layers of a resinous material and a photochromic polyurethane layer that is interspersed between the two resinous layers and which contains photochromic compounds. The polyurethane layer is formed by curing a mixture of a solid thermoplastic polyurethane, at least one isocyanate prepolymer, at least one photochromic compound, and a stabilizing system.

Abstract: Systems and methods for adding a functional layer to a lens having a plurality of microlenses for inhibition of ametropia. The lens may include defocus incorporated multiple segments (DIMS) having a plurality of microlenses or lenslets producing refraction areas with different refraction forces. Injection molding may be utilized to add a functional layer to such a DIMS lens having a plurality of microlenses or lenslets. The functional layer may add a functional utility to the lens, including but not limited to photochromic functionality, polarization functionality, and the like.

Abstract: A photochromic polyurethane laminate wherein the photochromic polyurethane layer of the laminate has been crosslinked with an isocyanate-active prepolymer using a crosslinking agent. The crosslinking agent is formulated to have at least three functional groups that are reactive with functional groups of the polyurethane or of the isocyanate-active prepolymer. A method of making the photochromic polyurethane laminate includes steps of causing the crosslinking.

Abstract: A wire grid polarizer having a mirror layer is laminated with a colored film. The colored film provides a scratch protection of the mirror layer of the wire grid polarizer and provides a colored mirror appearance of an optical lens made with such wire grid polarizer. The colored film laminated wire grid polarizer shows different intensities between the transmitted and reflected colors when the wire grid polarizer is paired with a particular colored film. The wire grid polarizer is deposited on a structured surface of a photochromic film to form a photochromic wire grid polarizer.

Abstract: An ophthalmic lens including an embedded functional wafer which is coated on one or both sides with a coating layer and methods for fabricating the same. The coating layer may provide adhesion between the functional wafer and the surrounding resin used to form the lens. The coating layer may also protect the functional wafer from degradation during fabrication, such as due to chemical attack or exposure to heat during thermoforming. The coating layer may be applied to a flat functional sheet and then subsequently formed into a curvature to match the lens, or the coating layer may be applied to an already-curved functional wafer. The coating layer may comprise various compositions known to provide adhesion, protection from heat, and/or protection from chemicals.
