Abstract
A lens for an automobile lamp, an automobile headlamp, and an automobile are disclosed. A lens (1) for an automobile lamp includes a first lens surface (11) and a second lens surface (12) opposite to the first lens surface (11). The first lens surface (11) is a curved surface or a planar surface. The second lens surface (12) includes multiple concentric circle-type annular surfaces. By means of multiple annular surfaces (13) disposed on the second lens surface (12) of the lens (1), parallel incident light that forms an angle with a horizontal direction can be separately incident on several small surfaces without affecting horizontal parallel light penetrating the lens and being focused, so that neither light reflected by the lens nor light penetrating the lens can be effectively focused.
