    摘要： Described is a method of preparing a cured, non-elastomeric polyurethane-containing film including: a) providing as a first component comprising a polyurethane material having isocyanate functional groups; b) providing as a second component a material having active hydrogen-containing functional groups that are reactive with isocyanate; c) combining the first and second components to form a reaction mixture; d) casting the reaction mixture onto a support substrate in a substantially uniform thickness to form a film thereon; e) heating the film on the support substrate to a temperature and for a time sufficient to yield a cured film; and f) removing the cured film from the support substrate to yield a non-elastomeric polyurethane-containing free film. The free film is non-birefringent. Optical elements and articles prepared from the films are also provided.

    摘要： Provided is a method for making a customized lens including applying a customizable material onto a surface of an ophthalmic substrate; and writing index-change information to the material to form a variable-index layer on the substrate surface. Also provided is a customized ophthalmic element including an ophthalmic substrate; and a variable-index layer of a liquid crystal material connected to at least a portion of the substrate. Further provided is an ophthalmic element having a pair of complementary substrates, each of which has a complementary surface and being positioned such that their complementary surfaces are spaced apart and facing each other, an alignment layer of a patterned alignment material connected to at least one of the complementary surfaces of the pair of substrates, and a variable-index coating interposed between the pair of substrates, such that the liquid crystal material of the variable-index coating is aligned with the patterned alignment material.
