1. An augmented lens assembly for use with a light source comprising:
a main lens component having a first side, an opposed second side, and at least one side edge; wherein the side edge is oriented to receive incoming light from a light source; wherein the opposed second side is oriented to transmit the incoming light from the main lens component;
a light source located adjacent to side edge of the main lens component;
at least one light refocusing element disposed on at least one of the first side and the second side of the main lens component; and
at least one baffle located adjacent to the augmented lens assembly; wherein the baffle comprises a material selected from a light transmissive, non-light transmissive, opaque, semi-opaque, refractive, and reflective material, and combinations thereof; and wherein the baffle extends outward from the opposed second side of the main lens component; wherein the position of the baffle is extendable from a position flush to the second side of the main lens component to a position extending outward from the second side of the main lens component;
wherein the at least one light refocusing element is characterized by at least one of a subtractive shape and an additive shape, the at least one light refocusing element has at least one surface that is not parallel to either the first side or the second side of the main lens component, and the at least one light refocusing element is positioned along at least one axis of the main lens component; and
wherein the at least one of the first side and the second side on which the at least one refocusing element is disposed and the at least one of the subtractive shape and the additive shape of the light refocusing element are selected based on a predetermined desired effect on a wavefront of the source light propagating through the main lens component and impinging on the at least one light refocusing element.
