Randomized Large 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 four rows of saccadic Fixation Disparity Cross stimuli presented with a 20/100 target size, reflective of the visual demands of larger print books. Two-dimensional Fixation Disparity Cross stimuli with Number Central Fusion Lock help relate binocular alignment to accommodation (clarity of the target)
Answer Key is imprinted on back of card for checking number accuracy and includes: Manual & Standard Polarized Viewer.
