This invention discloses methods and apparatus for providing a variable optic insert into an
ophthalmic lens. A liquid crystal layer may be used to provide a variable optic function and in
some embodiments, an alignment layer for the liquid crystal layer may be patterned in a
radially dependent manner. The patterning may allow for the index of refraction of the optic
device to vary in a gradient indexed or GRIN manner. At least a first layer of dielectric
material that may vary in thickness at least across the optic zone of the device may aid in …
