GT2 by ZEISS: The Science of Satisfaction.

The article highlights the ZEISS Optical Optimization & Management process used by Carl Zeiss Vision in developing GT2 lens in the U.S. The author stated that ZEISS has always relied on a sophisticated lens design process that delivers the most advanced progressive lenses available. He added that careful management of the overall global configuration of the lens design is the first stage of the ZEISS Optical Optimization & Management process. Moreover, the second stage of the process is an intensive, point-by-point refinement of the entire lens surface using computer raytracing and sophisticated optimization routines.
