1. A method comprising:
- depositing an electro-chromic material over a first surface having a first surface normal to form a first nanostructured electro-chromic layer over an ophthalmic substrate by exposing the first surface to a flux of the electro-chromic material traveling in a first direction;
wherein an incident angle between the first direction and the first surface normal is at least 1 degree and at most 89 degrees, andwherein the ophthalmic substrate is a member of the group consisting of a lens blank or a semi-finished lens blank.

Abstract
EC film stacks and different layers within the EC film stacks are disclosed. Methods of manufacturing these layers are also disclosed. In one embodiment, an EC layer comprises nanostructured EC layer. These layers may be manufactured by various methods, including, including, but not limited to glancing angle deposition, oblique angle deposition, electrophoresis, electrolyte deposition, and atomic layer deposition. The nanostructured EC layers have a high specific surface area, improved response times, and higher color efficiency.
