Method for constructing variable anamorphic lens

Claim 1

A PROCESS OF CONSTRUCTING SURFACES HAVING COMPOUND OPTICAL CURVATURE FOR A VARIBLE ASTIGMATIC LENS COPRISING THE STEPS OF PROVIDING PAIRED UPPER AND LOWER HOLLOW CYLINDERS HAVING SIDEWALLS WITH A HALLOW INTERIOR THERE BETWEEN, FORMING ON EACH SAID CYLINDER SIDEWALL WITH RESPECT TO A PLANE TAKEN NORMAL TO THE AXES OF GENERATION OF SAID CYLINDER A WALL HEGHT H ALONG THE SIDES OF SAID CYLINDER, SAID WALL HEIGHT H BEING DEFINED BY THE TERMS: H = A((X**3/3) - XY**2) + G WHEREIN: X REPRESENTS THE DISPLACEMENT ON A CARTESIAN COORDINATE SYSTEM FROM THE AXIS OF GENERATION OF THE CYLINDER TO THE WALL HEIGHT OF THE CYLINDER, Y REPRESENTS THE DISPLACEMENT ON A CARTESIAN COORDINATE SYSTEM WHEREIN Y IS AN AXIS SUBSTANTIALLY NORMAL TO SAID X AXIS AND TO THE AXIS OF GENERATION OF SAID CYLINDER, A IS A CONSTANT REPRESENTING LENS POWER VARIATION, G IS A CONSTANT CONTROLLING THE MAXIMUM DESIRED CYLINDER HEIGHT, AND H IS THE WALL HEIGHT BETWEEN A PLANE NORMAL TO THE AXES OF GENERATION OF SAID CYLINDER AND THE FORMED WALL HEIGHT ON SAID CYLINDER, AND, INCLUDING THE FURTHER STEPS OF CONFRONTING SAID CYLINDERS IN AN ORIENTATION WHEREIN THE RIDGES ON ONE CYLINDER ARE ALIGNED TO THE VALLEYS ON THE ADJACENT CONFRONTING CYLINDERS, DISPOSING A PIECE OF DEFORMABLE PLASTIC MATERIAL THEREBETWEEN HAVING PLANAR INTERFACES DISPOSED TOWARDS EACH OF SAID CYLINDERS, AND, MOVING SAID CYLINDERS TOWARDS ONE ANOTHER INTO COOPERATIVE CONTACT WITH SAID MATERIAL, IN THE PRESENCE OF HEAT TO PRODUCE A DEPTH FORMATION OF SAID MATERIAL BY PERMANENTLY DEFORMING SAID MATERIAL TO THE CONFRINTED RIDGES AND VALLEYS OF SAID CONFRONTED CYLINDERS WITHOUT DESTROYING SAID INTERFACES.
