A patient with an exophoria will see the image move to which direction as the paddle is switched from covering the left eye to the right eye?

Explanation:
Exophoria is a latent outward misalignment that is kept in check by fusion when both eyes are open. In the paddle test, you alternately occlude each eye to reveal that latent deviation. When fusion is disrupted, the eye that would drift outward moves relative to the target, causing the seen image to shift toward the side of the eye that is currently occluded. So, as the paddle switches from covering the left eye to covering the right eye, the image will appear to move to the right.
