The Maddox wing is designed to work at 30cm. The patient looks through two slit holes and the presence of a septa means that separate views are seen by each eye i.e. different targets are presented to each eye so fusion cannot occur. The right eye sees arrows while the left eye sees tangent scales. The Maddox wing is used for quantifying near phoria.
