A computer-implemented method (100, 200) for determining an improved design for a progressive lens, the method comprising the following steps: • Obtaining (110, 210) an aberration information of an eye, the aberration information comprising lower order aberrations of the eye and higher order aberrations of the eye, wherein the lower order aberrations are aberrations up to and including second radial order Zernike polynomials; • Obtaining (120, 220) a design optical power distribution, wherein the design optical power distribution is designed to correct for the lower order aberrations of the eye and to provide for a desired addition power based on a model of the aberrations of the eye, wherein the model includes aberrations only up to and including second order; • Obtaining a first design of the progressive lens, wherein the first design of the progressive lens is determined to provide for the design optical power distribution based on the model of the aberrations of the eye, wherein the model includes aberrations only up to and including second order; • Calculating (130, 230) a perceived optical power distribution perceived by the eye based on the first design of the progressive lens, the lower order aberrations of the eye and the higher order aberrations of the eye which are the lower order aberrations and the higher order aberrations of the obtained aberration information of the eye; • Determining (140, 240) a translation of the first design of the progressive lens and/or a rotation of the first design of the progressive lens, such that a deviation between the perceived optical power distribution and the design optical power distribution is minimized; and • Determining (150, 270) the improved design of the progressive lens by translating and/or rotating the first design of the progressive lens according to the determined translation and/or rotation. • Obtaining (110, 210) an aberration information of an eye, the aberration information comprising lower order aberrations of the eye and higher order aberrations of the eye, wherein the lower order aberrations are aberrations up to and including second radial order Zernike polynomials; • Obtaining (120, 220) a design optical power distribution, wherein the design optical power distribution is designed to correct for the lower order aberrations of the eye and to provide for a desired addition power based on a model of the aberrations of the eye, wherein the model includes aberrations only up to and including second order; • Obtaining a first design of the progressive lens, wherein the first design of the progressive lens is determined to provide for the design optical power distribution based on the model of the aberrations of the eye, wherein the model includes aberrations only up to and including second order; • Calculating (130, 230) a perceived optical power distribution perceived by the eye based on the first design of the progressive lens, the lower order aberrations of the eye and the higher order aberrations of the eye which are the lower order aberrations and the higher order aberrations of the obtained aberration information of the eye; • Determining (140, 240) a translation of the first design of the progressive lens and/or a rotation of the first design of the progressive lens, such that a deviation between the perceived optical power distribution and the design optical power distribution is minimized; and • Determining (150, 270) the improved design of the progressive lens by translating and/or rotating the first design of the progressive lens according to the determined translation and/or rotation.
