Claims

[Scope of utility model registration request]

Substantially the entire back surface of the lens is divided into a display pattern forming part and a non-display pattern forming part for forming a desired display pattern such as characters, figures, or symbols, and the display pattern forming part has a focal point in front or behind it. A first lens step consisting of a condensing or diffusing lens element is provided, and a second lens element having a curvature different from that of the lens element formed in the first lens step is provided in the non-display pattern forming section. A front lens for a vehicle lamp, characterized by forming a lens step.
