WATER GRADIENT SILICONE HYDROGEL CONTACT LENSES

The invention provides an easy-to-remove water gradient contact lens. Such a water gradient contact lens comprises imperfections (ditches and/or gaps) in the anterior outer hydrogel layer and can be made according to a cost-effective method involving a step of partially or completely shielding reactive functional groups in selected zones on the anterior surface a to-be-coated contact lens before grafting a layer of a non-silicone hydrogel material. With the imperfections in the anterior outer hydrogel layer, the surface lubricity of the anterior surface is inferior to that of the posterior surface. By adjusting the shape, size, density, and rotational distribution of the imperfections, one also can selectively adjust and optimize the surface lubricity of the anterior surface of a water gradient contact lens so as to have improved lens handlability while maintaining other desirable properties.
