Abstract
An apparatus for assisting in establishing a correction for correcting heterotropia or heterophoria is disclosed. The apparatus tests a prescription for correcting the heterotropia or heterophoria before the prescription is actually realized. The apparatus includes a simulation device with an input interface, a generator unit, and a viewing device. The input interface receives diagnostic data, classification data, and magnitude data concerning the heterotropia or heterophoria, and prescription data indicating a suitable prism. The generator unit generates a right simulation image for the right eye and a left simulation image for the left eye, wherein the right and left simulation images each represent the same object or scene looked at by the respective viewing angles of the eyes. The viewing device has separate displays or display sections for displaying the simulation image to the right eye and the left eye of the patient.
