FIELD: medicine.
SUBSTANCE: invention refers to a hydrated silicone hydrogel contact lens. The lens has a layered structural configuration. A hydrogel core of the lens has the low water content and is completely covered with a layer of a water-rich, e.g. the water content more than 80%, hydrogel totally or substantially free from silicone.
EFFECT: hydrated silicone hydrogel contact lens possesses high oxygen permeability for maintaining the corneal health and a soft, water-rich smooth surface for wearing comfort.
