Small Fixation Disparity Polarized Target

Small Fixation Disparity Polarized Target Vectographic two-dimensional card with 2 Fixation Disparity Crosses positioned vertical to one another to facilitate the comparison of binocular performance when using a lower versus higher spatial frequency or acuity demand. Top Fixation Disparity Cross at 20/95 acuity level reflective of visual demands of larger print books and bottom Fixation Disparity Cross at 20/63 acuity level more reflective of reading demands at higher grade levels (smaller print books).

Sensitive to suppression and measures vertical & horizontal binocular function for assessing Near Point of Fixation Disparity (NPFD) (50 inches / 127cm) & Associated Vergence Measures at Near (16 inches - 18 inches/ 41cm - 46cm). Two-dimensional Fixation Disparity Cross stimuli with E Central Fusion Lock help relate binocular alignment to accommodation (clarity of the target).

Small Fixation Disparity Polarized Target Vectograph includes manual and standard polarized viewer.
