Not Accessible

Your library or personal account may give you access

Abstract

A new method for characterizing the design of progressive addition lens is presented. The power gradient of the lens is measured in a small area using an automatic lensmeter. This measurement, designated PV, is repeated on selected, separated areas of the lens to create a profile of the lens gradient change. Results of measurements taken on lens of different designs are presented.
