A system and method for determining a lateral position of an eye relative to an ophthalmic device are disclosed. One embodiment of the method includes receiving data comprising an image of a surface of an eye. An edge feature in the image is located, wherein the edge feature is in a known relationship to a pupil of the eye. The image is mapped from the edge feature to laterally define the pupil, and a center of the pupil is determined using the pupil definition. The pupil center comprises a location from which to achieve a preferred lateral eye position relative to an ophthalmic device. An embodiment of the system of this invention can include a processor and a software package executable by the processor, the software package adapted to cause the processor to carry out the method steps.
