The shifting field of Förster refers to the field which is wider on the side on which the test is begun.³ Thus, if we begin on the nasal side and cross over to the temporal side, through the fixation point, the test object will be seen for a greater distance on the nasal side and will disappear more quickly on the second, or temporal, side.
