MINIATURIZED AMD VISION AIDS: PRINCIPLES AND REALIZATION

In this paper we discuss two kinds of adapted vision aids for people suffering from AgeRelated Macular Degeneration(AMD). Both concepts aim at redirecting the central visual information which cannot be seen by AMD patients to the outer, unimpaired parts of the retina. The first kind of vision aid redirects the central fieldof viewusing prismatic elements and magnifies it homogeneously with Galileantelescopes. The second principle is based on anamorphicprism pairs and leads to a one dimensional magnification of the full fieldof view. In both cases we apply segmented optics to realize the complex optical functions with lowweight components suitable for all day use. Replication in PDMS is discussed as an efficient fabrication process for segmented elements.
