Abstract

A vehicle lamp includes a light source, and an aberration correction lens unit, that corrects chromatic aberration, irradiates in a frontward direction with direct light from the light source. The aberration correction lens unit includes a first lens located in a front side of the light source, and a second lens located in front of the first lens. The aberration correction lens unit performs vibration control for vibrating intersections in a front-back direction. The intersections are intersections of an optical axis, and red, green, and blue components of white light incident in parallel from the front toward the outside in the radial direction from the optical axis side of the aberration correction lens unit.
