1. A method of making a multi-layered mesogen coatings for ophthalmic lenses comprising:
providing a thin film comprising organic polymers and having a controlled retardation to convert linearly polarized light to circularly polarized light;
coating the thin film comprising the organic polymers with an alignment layer comprising a polyurethane dispersion or silanes;
coating a mesogen layer onto said alignment layer of said thin film;
annealing said thin film containing said mesogen layer in an oven;
curing said mesogen layer of said thin film; and
coating at least a second mesogen layer onto said cured mesogen layer of said thin film to form a bi-layered mesogen coatings and annealing and curing said second mesogen layer; and
repeating the steps of coating, annealing and curing of mesogen coatings to form the multi-layered mesogen coatings for said ophthalmic lenses.
