The present disclosure relates to a lamp lens with a reduced chromatic aberration, and a lamp for a vehicle using the same. In the lamp lens with a reduced chromatic aberration, a thin film formed of a predetermined material is coated or deposited on a surface of the lamp lens and the thin film is formed within 30% of a diameter of the lamp lens above and below a center of the lamp lens, to increase a reflection of light in a specific wavelength band, thereby efficiently reducing a chromatic aberration.
