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: 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.
