Paper Abstract

This paper describes a simple Hartmann test data interpretation that can be used to evaluate the performance in spherical ophthalmic lenses. Considering each spot of the Hartmann pattern like a single ray, using traditional ray tracing analysis it is possible to calculate the value of the spherical power in the point corresponding with each spot. The values of spherical power for each spot obtained by this procedure are used to obtain a spherical power distribution map of the entire lens.
