Try to move your eyes smoothly from left to right and back looking across your room. Your eye will probably actually move in a jittery pattern of fast sweeps (saccades) and brief stops (fixations). When you are reading, the eyes move very similarly. The brain blocks out the images from the eye during the bursty movements, avoiding motion blur. This makes it very difficult to ever see your own eyes moving in the mirror.
