Abstract

An optical testing instrument, the Eyeglass Image Quality Mapper, has been developed that maps the power, astigmatism, and modulation transfer function over the surface of a progressive addition eyeglass lens. This instrument models the manner in which the eye views different regions of the lens and is automated so that testing can be performed without supervision and in a reasonable amount of time.In this paper, we describe the concept development, final design, and use of the instrument.
