PHOTOCHROMIC OPTICAL ELEMENT

摘要

Described are optical elements made of a substrate having connected thereto an at least partial film of photochromic adhesive and an at least partial film of a polymeric organic material. Also described are optical elements made of a substrate having connected thereto an at least partial superstrate of a photochromic composite of a film of a first polymeric organic material and a film of a second polymeric organic material having an at least partial film of a photochromic adhesive placed between the films of first and second polymeric organic materials. Methods to prepare the optical elements are also described.
