Abstract
A near field lens is for an automotive light assembly, generally comprising a central body positioned between opposing side bodies. The central body extends in a vertical direction, while the side bodies are positioned on horizontal sides of the central body. The opposing side bodies are structured to collimate the light both horizontally and vertically, while the central light body is structured to collimate the light vertically but not substantially collimate the light horizontally.
