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

Explanation:
Latent inward deviation (esophoria) is kept in check by fusional vergence, but when fusion is disrupted by covering one eye, the eye with the latent inward tendency drifts toward the nose. That inward drift makes the viewed image appear to shift in the noseward direction. On a typical horizontal field, that translates to the image moving to the left when the paddle is switched from covering the left eye to covering the right eye.
