In fully blind persons in whom homogenizing of visual sphere is maximum, violation of parameters of automaticity of saccades also reaches its maximum: 100% of saccades are oriented in one direction and they all are larger in amplitude. As a result the eyes of a blind person look senselessly roving. Just by that criterion it is so easy to distinguish a blind person from a sighted one. Similar abnormalities of saccadic automaticity can be found in puppies when kept under black-out conditions.
