= EMBEDDED CONTACT LENS WITH A HIGH REFRACTIVE INDEX INSERT THEREIN =

'''Abstract''':
the invention provides a composite material suitable for making hydrogel contact lenses and especially diffractive inserts to be embedded in hydrogel contact lenses. a composite material of the invention has a relatively high refractive index (ri) and is composed of a hydrogel material and high ri nanoparticles which are distributed in the polymer matrix of the hydrogel material and present in an amount sufficient high to provide the composite material with a high ri but sufficient low to provide the composite material with a light transmissibility of 85% or greater in the range between 450 to 700 nm.
