    摘要: Various non-limiting embodiments disclosed herein relate generally to photochromic compounds, which may be thermally reversible or non-thermally reversible, and articles made therefrom. Other non-limiting embodiments relate to photochromic-dichroic compounds, which may be thermally reversible or non-thermally reversible, and articles made therefrom. For example, one non-limiting embodiment provides a thermally reversible, photochromic compound adapted to have at least a first state and a second state, wherein the thermally reversible, photochromic compound has an average absorption ratio greater than 2.3 in at least one state as determined according to CELL METHOD. Another non-limiting embodiment provides a photochromic compound comprising: (a) at least one photochromic group chosen from a pyran, an oxazine, and a fulgide; and (b) at least one lengthening agent L attached to the at least one photochromic group and represented by the formula—[S1]c-[Q1 —[S2]d]d′-[Q2 —[S3]e]e′-[Q3 —[S4]f]f′—S5—P, which is described herein.

    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.
