ABSTRACT:
A method and system for automatically inspecting an ophthalmic lens. The method includes the steps of directing a light beam through the lens and onto an array of pixels, and assigning to each pixel a data value representing the intensity of the light beam on the pixel. The data values are then processed according to a predetermined program to determine if the lens contains any one of a group of predetermined conditions.
