Methods are disclosed for manufacturing a coated contact lens that comprises a polymeric lens body comprising an acid group, a first coating polymer comprising a first amine group ionically bound to the acid group, and a second coating bound to the first coating polymer through covalent linkage between a nitrogen atom of a second amine group on the first coating polymer and an amine-reactive group of the second coating polymer. In some examples the lenses exhibit improved surface properties compared to uncoated lenses, such as reduced adhesion, increased wettability, increased lubricity, and/or increased lipid resistance.揭示製造經塗覆隱形眼鏡之方法,該經塗覆隱形眼鏡包含含有酸基團之聚合鏡片主體、包含離子結合至該酸基團之第一胺基團之第一塗層聚合物及第二塗層,該第二塗層藉助該第一塗層聚合物上之第二胺基團之氮原子與該第二塗層聚合物之胺反應性基團之間之共價鏈接結合至該第一塗層聚合物。在一些實例中,該等鏡片與未塗覆鏡片相比展現經改良表面性質,例如減低之黏附性、增加之潤濕性、增加之潤滑性及/或增加之脂質抗性。
