A method for producing an optical silicone assembly is disclosed. The method comprises the steps of: i) treating a surface of a substrate with an optically clear silicone adhesive composition; ii) placing the substrate obtained by step i) into a mold; iii-a) injecting an optically clear moldable silicone composition into the mold, and/or iii-b) overmolding the optically clear moldable silicone composition onto the substrate; and then iv) heating the optically clear moldable silicone composition to form the optical silicone assembly. The optical silicone assembly produced by the method of this disclosure is characterized by excellent adhesion of an optical silicone product to various types of substrates.
