    Abstract: Methods are disclosed for manufacturing a coated contact lens that comprises a polymeric lens body comprising an acid group, a first coating polymer comprising a first amine group ionically bound to the acid group, and a second coating bound to the first coating polymer through covalent linkage between a nitrogen atom of a second amine group on the first coating polymer and an amine-reactive group of the second coating polymer. In some examples the lenses exhibit improved surface properties compared to uncoated lenses, such as reduced adhesion, increased wettability, increased lubricity, and/or increased lipid resistance.

    Abstract: The present disclosure provides a contact lens comprising a first colourant which is a blue-blocking colourant having an absorption maximum (λmax) in the range of from 415 nm to 455 nm and a second colourant, wherein the second colourant is a polymerizable dye having an absorption maximum (λmax) in the range of from 470 nm to 600 nm, and optionally also comprising a third colourant which is a colourant having an absorption maximum in the range of from greater than 600 nm to 800 nm. A method of making the lens is also provided.

    Abstract: A cationic contact lens is described as well as methods of manufacturing the same. The cationic contact lens includes a polymeric lens body that is the reaction product of a polymerizable composition that includes at least one siloxane, at least one nonionic hydrophilic monomer and at least one acyclic tertiary amine monomer. The cationic contact lens can be an unworn sterile silicone hydrogel contact lens. The contact lens is capable of substantially linear release of a releasable anionic agent and the at least one acyclic tertiary amine monomer facilitates uptake and/or sustained release of the releasable anionic agent by the polymeric lens body. The contact lens can be present in a sealed contact lens package. The sealed contact lens package can include at least a) a base member having a cavity; b) a contact lens packaging solution in the cavity; c) a unworn sterile contact lens immersed in the contact lens packaging solution in the cavity with the releasable anionic agent present; and d) a cover that forms a liquid-tight seal with the base member.

    Abstract: A contact lens having an amount of at least one cooling agent and at least one TRPV1 inhibitor releasably adhered is described as well as method of manufacturing the same. The contact lens can be comfortably worn by contact lens wearers and can increase the duration of comfortable lens wearing time and/or reduce lens awareness events and/or reduce contact lens dryness in a symptomatic contact lens wearer and further can reduce or avoid any stinging/burning sensation when the contact lens is first used or a short time thereafter.
