Eye Contact

Researchers studying eye movement during normal conversation have found that sustaining eye contact for any length of time is difficult, if not impossible. Special cameras reveal that what appears to be a steady gaze at someone is actually a series of rapid scans of the face. Eye movement is essential because the nerves in the eye need a constant change of stimulation if we are to see properly. Studies show that if we look at the same spot continuously, the rest of our visual field will go blank.
