Abstract
An optical article of manufacture and a method of making the article of manufacture are disclosed. The article of manufacture includes an optical component including a junction between a first region having a first optical power and a second region having a second optical power. The first optical power is different from the second optical power. The article further includes an occlusion ring included in the optical component and aligned with the junction. The method includes forming a thin film polymer layer on a substrate. The method further includes forming an occlusion ring on the thin film polymer layer. The occlusion ring has an inner occlusion ring region and an outer occlusion ring region. The method further includes forming an outer wire grid polarizer on the outer occlusion ring region.
