Described herein is a method for producing centrally colored silicone hydrogel contact lenses. The method comprises a step of cast molding of a lens-forming composition including a hydroxyl-containing polymerizable component to form an unprocessed silicone hydrogel contact lens having hydroxyl groups covalently incorporated into its polymer matrix and steps of applying and fixing a reactive dye to the polymer matrix only in its central circular region concentric with the central axis of the unprocessed silicone hydrogel contact lens. The obtained centrally colored silicone hydrogel contact lens has a central circular region that is only colored to selectively filter radiations of certain wavelengths, e.g., HEVL.
