Dominant eye Dominant or leading eye is the eye that we use when we look very carefully at near or at far and can use only one eye. Even when both eyes are used simultaneously one of the eyes is more dominant than the other. We have hand, foot, and eye preference. Eye motility and its disturbances Eye movements are usually well controlled. The eyes look at the same object.
Eyes turn because of the function of six eye muscles.
Eye muscles seen from above. The left outer muscle has developed palsy , the left eye turns inward. If an eye muscle is not functioning properly the person sees double when trying to look in the direction where the muscle should function. When the eyes are turned in the opposite direction the double image is fused again. The eye with the disturbed motility is covered until the muscle function returns to normal.
