摘要:
A synthetic resin layered lens for a vehicle lighting device in which an upper lens layer is disposed on a lower lens layer thereby forming a layered lens of integral construction. The lower lens layer is molded in a state that the surface of the lower lens layer where it contacts the upper lens layer, faces the injection gate. The gate scar of the lower layer is thus hidden by the upper layer.
