The present disclosure provides a contact lens comprising a first colourant which is a blue-blocking colourant having an absorption maximum (λ) 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 (λ) 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.

Contact lens

A method of making a contact lens comprising the steps of reacting in a mold a polymerizable formulation comprising at least one fluorine-containing silicone monomer at least one non-fluorine-containing silicone monomer and at least one hydrophilic monomer to form a contact lens, subjecting the contact lens to one or more solvent extraction steps to remove impurities, oligomers and unreacted monomers and hydrate the contact lens, wherein all of the solvent extraction steps are undertaken using an aqueous solvent.

Method of making a contact lens

A contact lens formed of a composition comprising the reaction product of: A) at least 10 weight percent, based on the total composition weight excluding solvent, of at least one silicone-containing monomer of the formula I: where n is from 1 to 3, m is from 9 to 15, each a independently is Calkyl, and each b independently is Calkyl; B) at least 10 weight percent, based on the total composition weight excluding solvent, of 3-methacryloxypropyl tris(trimethylsiloxy)silane; C) N-vinyl pyrrolidone; and D) at least one other non-ionic hydrophilic monomer wherein the combined amount of A) and B) is at least 20 weight percent based on the total composition weight excluding solvent, and wherein the N-vinyl pyrrolidone (NVP) is present in such an amount that the reaction product comprises polyvinyl pyrrolidone (PVP) homopolymer.
