Abstract

Ray-tracing through Progressive Addition Lenses (PAL) has been performed. PAL is a deep non rotationally symmetric asp1ric lens used for the compensation of presbyopia. PAL and its mathematical model are presented. The special features of the ray-tracing program due to the model of the lens plus eye system are detailed. Typical results are presented showing in particular that computing conditions of contour-plots of power and astigmatism must be very strict and that coma must be taken into account for precise measurements of PAL. 1.
