Randomized Small Fixation Disparity Polarized Target
Randomized Small Fixation Disparity Polarized Target Assessment tool for measuring binocular/accommodative function during a saccadic eye movement task using a sequence of saccadic identification targets. Vectographic silvered card with five rows of saccadic Fixation Disparity Cross stimuli presented with a 20/63 target size to monitor visual, binocular & accommodative functions more reflective of reading demands at higher grade levels (smaller print books). Two-dimensional Fixation Disparity Cross stimuli with Number Central Fusion Lock help relate binocular alignment to accommodation (clarity of the target)
Randomized Small Fixation Disparity Polarized Target has answer Key imprinted on back of card for checking number accuracy and includes: Manual & Standard Polarized Viewer
