Abstract

A method for detecting the orientation of a contact lens (3) in a blister package (1) comprising the steps of placing a contact lens (3) having a convex side and a concave side into an open blister (2), aligning the blister (2) with a light source (12) and a digital camera (13), detecting a reflected and/or refracted image from the blister (2) and contact lens (3) with the digital camera (13) and determining whether a correctly oriented lens is present from a characteristic of the reflected and/or refracted image with an analysis means (15).
