Abstract: A system, method, and computer readable medium for determining at least one feature of at least one lens mounted in a spectacle frame. The system includes a non-point light pattern generating device configured to generate a predefined non-point light pattern, and arranged to have the predefined non-point light pattern reflected on the at least one lens, an image acquisition device configured to acquire an image of the spectacle frame including an image of the reflected non-point light pattern, and a processing unit configured to determine at least the contour of the at least one lens in function of at least one feature of the image of the reflected non-point light pattern.
