TLDR
In this article, a method for making monocentricric BIFOCAL contact LENSs is presented. The reading section is composed of a MATERIAL POSESSING and the OPTICAL CENTER of the reading segment is located at the center of the UPPER STRAIGHT EDGE of the SEMICIRCULAR READING SEGMENT.
Abstract: 
A METHOD FOR MAKING MONOCENTRIC BIFOCAL CONTACT LENSES. THE READING SEGMENT BEING COMPOSED OF A MATERIAL POSESSING A HIGHER INDEX OF REFRACTION THAN THE MATERIAL OF THE LENS AND BEING SEMI-CIRCULAR IN SHAPE AND THE OPTICAL CENTER OF THE READING SEGMENT LOCATED AT THE CENTER OF THE UPPER STRAIGHT EDGE OF THE SEMICIRCULAR READING SEGMENT.

Oxygen permeable bifocal contact lenses and their manufacture

Lisa A. Pettigrew, +3 more
TL;DR: An oxygen permeable bifocal contact lens with a Dk of at least 10×10-11 in which a distance vision portion having a refractive index of not more than 1.49 is formed as a pre-form in which there is provided a recess, and a near distance vision part having at least 1.540 is formed by filling the recess with a monomer mixture and polymerizing.
