WebFixation disparity is a tendency of the eyes to drift in the direction of the heterophoria.While the heterophoria refers to a fusion-free vergence state, the fixation disparity refers to a small misalignment of the visual axes when both eyes are open in an observer with normal fusion and binocular vision. The misalignment may be vertical, horizontal or both. WebJul 15, 2024 · Disparity. Binocular disparity is the difference in the images of a single object as seen by the two eyes.
