The present invention relates to a method for optimally designing a lens having a totally internal reflection (TIR) structure for a desired illumination function in an asymmetric illumination region. The method comprises the steps of: (220) designing a quasi collimated lens having a totally internal reflection (TIR) structure; and (230) independently or repeatedly performing optimized design for a cross-sectional shape of an exit surface of the lens by using the lens designed at once. The step (230) of performing optimized design for a cross-sectional shape of an exit surface of the lens comprises the steps of: (240) orthogonally coupling optimized 2-dimensional lens exist surface shapes to be a three-dimensional shape surface; and (250) coupling a quasi-collimated lens having a totally internal reflection (TIR) structure with the orthogonally coupled three-dimensional shape surface.
