This is a medical condition which is characterized by an inability to perceive faces. It is commonly known as “face blindness” — referring to an inability to remember faces, even those of people with whom one is familiar. Studies on prosopagnosia suggest that up to two percent of the population may be faceblind, and this estimate could be even higher with the assistance of better tracking and diagnostic tools. Currently, there is no known cure for prosopagnosia, although faceblind individuals can learn various tricks to help them get along socially. View My experiences of prosopagnosia.
