Randomized Large Fixation Disparity Polarized Target107103
The Randomized Large Fixation Disparity Polarized Target is an assessment tool that measures binocular/accommodative function during a saccadic eye movement task using a sequence of saccadic identification targets. This vectographic silver card features four rows of saccadic Fixation Disparity Cross stimuli presented with a 20/100 target size that is reflective of the visual demands of larger print books. The two-dimensional Fixation Disparity Cross stimuli with Number Central Fusion Locks help relate binocular alignment to accommodation (clarity of the target).
The answer key is printed on the back of the card for checking number accuracy and includes a manual and a standard polarized viewer.
