People who suffer from motion blindness have "normal vision": They can see different objects sharply, can tell the distance between them (that one is "farther away" than the other) and they see the different colors the objects might have. This applies to shapes, objects and faces. They do not, however, see the objects move. Besides simple perception, akinetopsia also disturbs motoric tasks which rely on visual perception, such as reaching for objects and catching objects. When doing tasks, feedback of one's own motion appears to be important.
