ABSTRACT:
An iris assembly of this invention comprises an iris button having a frontside surface. An iris member is joined to the iris button frontside surface and has an iris image disposed thereon. The iris image is provided using digital image capture, storage, enhancement, and printing techniques, and is provided onto a suitable substrate. A cornea piece is made from a clear material, and is joined to the iris member frontside surface. Prior to joining, the iris member is encapsulated with a clear protective film thereover that operates to protect the iris image from unwanted smudging or other type of distortion during the step of joining the cornea piece. Iris assemblies of this invention are constructed in a manner that provide a more accurate reproduction of the iris image, in a manner that is both time efficient and cost effective, when compared to conventional iris assemblies and methods for making the same.
