ABSTRACT:
A method for generating a virtual entity of an ophthalmic lens blank in a computer environment and for using this entity to monitor and control a lens generation process. The method comprises the steps of analyzing an image of a lens blank, measuring a first surface of a lens blank, probing a second surface, and locating both surfaces and the contour of the lens blank in a spatial coordinate system. These data are used to generate a virtual entity that is a precise representation of the lens blank. The virtual entity is used throughout the lens generation process for blocking the lens, for calculating and selecting lens orientation, skewing, prism, tool angles and ideal tool paths that produce best lens quality.
