A method of incorporating dyes into polymeric materials. The method involved contacting a functionalized dye with a high molecular weight cross linkable polymer precursor, dispensing the solution into a mold and applying radiation, thereby forming a molded article having dye covalently bonded to the polymer backbone. A preferred product is a visibility tinted disposable contact lens comprising poly(vinyl alcohol). Various embodiments of the innovative method offer advantages in reduced fabrication cycles, reduced extractables, elimination of post-polymerization steps and reduced scrap and costs associated with lens handling.
