Abstract: Multilayer contact lenses and methods of making the same are described. A contact lens (100) includes a lens assembly (103). The lens assembly (103) includes a plurality of flexible lens layers. A first layer (101) has a uniform or smooth anterior surface (106), and a second layer (102) has a structured posterior surface that includes one or more recesses (105). The anterior surface (106) of the first layer (101) and the structured posterior surface of the second layer (102) define a first cavity (107) for containing one or more components.
