More Information
Summary:The invention provides a delamination-resistant embedded silicone hydrogel contact lens having an insert that is embedded in a silicone hydrogel bulk material. The insert is made of a crosslinked polymeric material having a refractive index higher than that of the silicone hydrogel bulk material by at least 0.07 and comprises a diffractive structure disposed on one of the front and back curve surfaces of the insert for providing a diffractive power that contributes to the overall optical power of the contact lens.
