    Abstract: A method for producing silicone hydrogel contact lenses and silicon hydrogel contact lens thereof. The method comprising the steps of: providing a mold for making a soft contact lens, wherein the mold has a first mold half with a first molding surface defining the anterior surface of a contact lens and a second mold half with a second molding surface defining the posterior surface of the contact lens, wherein said first and second mold halves are configured to receive each other such that a cavity is formed between said first and second molding surfaces; introduce a monomer mixture of lens-forming materials into the cavity, wherein the monomer mixture comprises at least one hydrophilic amide-type vinylic monomer, at least one siloxane-containing (meth)acrylamide monomer, at least one polysiloxane vinylic monomer or macromer, and from about 0.05 % to about 1.5 % by weight of a photoinitiator, wherein the lens forming material is characterized by having an ability to be cured by a UV light having an UV-intensity of about 4.1 mW/cm 2 within about 100 seconds; and irradiating, under a spatial limitation of actinic radiation, the lens-forming material in the mold for a time period of about 120 seconds or less, so as to crosslink the lens-forming material to form the silicone hydrogel contact lens, wherein the produced contact lens comprises an anterior surface defined by the first molding surface, an opposite posterior surface defined by the second molding surface, and a lens edge defined by the spatial limitation of actinic radiation.

    Abstract: Described herein is a cost-effective and time-efficient method for making UV-absorbing contact lenses. In contrast to the conventional method for making UV-absorbing contact lenses which involves copolymerizing a lens forming composition including a UV-absorbing vinylic monomer, a method of the invention involves covalent attachment of a UV-absorbing compound having a second reactive functional group to a preformed contact lens having a first reactive functional group therein and/or thereon.
