When any joint is moved in such a way that the angle between the two bones of the joint decreases i.e. the two ends of the bones come closer, then the movement is called Flexion. In the second case when we try to rub our eyes we fold the elbow, hence the angle of elbow joint decreases. So, it is an example of flexion.
