Claim 0:
1. An eye-mountable device, comprising
a first rigid polymer layer having a first-layer refractive index;
a second rigid polymer layer having a second-layer refractive index; and
a first liquid crystal layer between the first and second rigid polymer layers, wherein the first liquid crystal layer has an ordinary refractive index and an extraordinary refractive index,
wherein
the first-layer refractive index and the second-layer refractive index differ by less than 0.01,
the ordinary refractive index and the extraordinary refractive index differ by more than 0.1,
the first-layer refractive index differs from either the ordinary refractive index or the extraordinary refractive index by less than 0.01, and
the first rigid polymer layer or second rigid polymer layer comprise:
one or more di(meth)acrylate-derived monomeric unit, wherein the one or more di(meth)acrylate-derived monomeric unit comprises diphenyl methacrylate; and
one or more (meth)acrylate-derived monomeric units, wherein the one or more (meth)acrylate-derived monomeric units comprise phenyl methacrylate.
