摘要：

Hydrated silicone hydrogel contact lens having a layered structural configuration: a low water content silicone hydrogel core (or bulk material) completely covered with a layer of a water-rich (e.g., a water content greater than 80%), hydrogel totally or substantially free of silicone. The hydrated silicone hydrogel contact lens possesses high oxygen permeability for maintaining the corneal health and a soft, water-rich, lubricious surface for wearing comfort.
