| 1. Method for designing and optimizing an individual spectacle lens, said method comprising the acts of:
making a draft design at an ophthalmologist's site on a video workstation by means of a computer program;
communicating the draft design to a manufacturer or an optical computing office; and
optimizing an individual spectacle lens on the basis of the communicated draft design, wherein making the draft design comprises:
(a) defining a type of spectacle lens;
(b) establishing an object distance as a function of a horizontal and a vertical coordinate;
(c) optionally establishing an accommodation;
(d) selecting regions of good vision from a set of given designs, or setting up regions of good vision by adjusting a shape
of borderlines which separate zones of good vision from zones of poor vision; and
(e) determining a location and a magnitude of a maximum imaging error or a minimum visus.
