	First Claim: Show all 27 claims			What is claimed: 1. An oriented, optically corrected non-prescription dual lens to eyeglass, comprising: a left non-glass lens body and a right non-glass lens body, said left lens body having a left mechanical center and said right lens body having a right mechanical center; a frame for supporting the right lens in the path of a wearer's normal line of sight from a right eye and the left lens in the path of a wearer's normal line of sight from a left eye, each lens exhibiting an amount of wrap and an amount of rake in an as worn orientation with respect to the wearer's right and left normal lines of sight; a front surface and a rear surface on each of the right and left lens bodies, defining a lens thickness therebetween for each of the right and left lenses; each of the front surface and rear surface of the right lens conforming substantially to portions of the surfaces of a front right sphere having a first center and a rear right sphere having a second center, respectively, such that the thickness of the right lens is tapered in both horizontal and vertical planes; each of the front surface and rear surface of the left lens conforming substantially to portions of the surfaces of a front left sphere having a third center and a rear left sphere having a fourth center, respectively, such that the thickness of the left lens is tapered in both horizontal and vertical planes; each of said first, second, third and fourth centers offset from one another; a right optical centerline extending through the first and second centers of the right lens; a left optical centerline extending through the third and fourth centers of the left lens; wherein the right mechanical center is offset both horizontally and vertically from the right optical centerline, by a vertical distance which corresponds to the amount of rake exhibited by the right lens in the as worn orientation and by a horizontal distance which corresponds to the amount of wrap exhibited by the right lens in the as worn orientation, and the left mechanical center is offset both horizontally and vertically from the left optical centerline, by a vertical distance which corresponds to the amount of rake exhibited by the left lens in the as worn orientation, and by a horizontal distance which corresponds to the amount of wrap exhibited by the left lens in the as worn orientation to produce eyewear which is optically corrected for prismatic error which would otherwise have been induced by said rake and wrap.
