Biomedical devices, such as ophthalmic lenses, and methods of making such devices having a surface coating including at least one polyionic layer. A preferred method involves spray coating a polycationic material onto a core lens, rinsing and drying the lens, followed by spray coating a polyanionic material, rinsing and drying. The coating process may be applied a plurality of times to achieve a multi-layer coating on the lens surface. A particularly preferred embodiment is a contact lens comprising a highly oxygen permeable hydrophobic core coated with a 5 to 20 bilayers of hydrophilic polyionic materials.
