Abstract

A method for designing a progressive lens is disclosed. The method includes obtaining a wavefront measurement of an eye, determining an initial design for the progressive lens based on the wavefront measurement, determining information about how changes in one or more higher order aberrations of the eye affect a second order correction for the aberrations of the eye based on information derived from the wavefront measurement, modifying the initial design of the progressive lens to provide a final progressive lens design, and outputting the final lens design.
