Methods of loading biologics onto contact lenses for use as drug-delivering ophthalmic devices are provided, as are contact lenses made by such methods and methods of treatment employing such contact lenses, while maintaining optical clarity and structural rigidity. The lens material has at least one concentric layer consisting of a porous material with pores large enough to deliver a biologic to a subject over a desired time period of diffusion. The concentric layers are formed through polymerizing a first, outer layer in a rotating cylinder and then repeating the method the desired number of times with different formulations for the different layers.
