Hybrid diffractive–refractive achromatic spectacle lenses

Abstract

The possible utility of high‐power hybrid achromatic spectacle lenses, each consisting of a contact combination of refractive and diffractive components, is considered. It is shown that such a combination can, in principle, minimize blur due to transverse chromatic aberration in high‐power prescriptions such as those for uphakes and high myopes. The combination has essentially the same thickness and weight as a conventional singlet lens. Some practical problems relating to hybrid designs are discussed. Copyright © 1994, Wiley Blackwell.
