Abstract
A method for optically inspecting an ophthalmic lens in an automated lens production process to determine an orientation state and an inversion state of the ophthalmic lens. The method comprises the steps of acquiring an image of the ophthalmic lens, determining from the acquired image an orientation value of the lens, comparing the determined orientation value with an orientation threshold value, and determining that the lens is oriented right side up when the determined orientation value is higher than the orientation threshold value, or determining that the lens is oriented upside down when the determined orientation value is lower than the orientation threshold value, or vice versa.
