Corrective mirror assembly

Claim 1

A corrective mirror assembly adapted to the needs of a specific individual who requires spectacles for close work, comprising a plano-convex means ground substantially to the optical characteristics of one of the lenses of the spectacles of such individual, said plano-convex lens means including a reflective mirror surface on the planar side of said plano-convex lens means and being ground to a power one-half that of a similar lens which would focus onto the retina of an eye of such individual, an object located twice the distance from said eye that said lens means is supported in use, a second plano-convex lens ground substantially to the optical characteristic of the remaining lens of the spectacles of said individual, said second lens means including a reflective mirror surface on the planar side of said second plano-convex lens means, said second lens means being ground to the power one-half that of a similar lens which would focus onto the retina of the other eye of said individual, an object located twice the distance from the said other eye that said lens means is, when supported in use, said distance from each eye being on the order of 20 centimeters, each of said plano-convex means being housed in its own respectacle with the convex surface facing said individual when in use, said receptacles being connected by hinge means such that the distance between centers of said lens-mirror combinations correspond substantially to the interpupillary distance of said individual.
