THE uncanny ability of blind people to "sense" unseen objects has been demonstrated for the first time in sighted volunteers whose vision was blanked out by scientists.
The findings suggest "blindsight", which has been observed in blind people whose eyes function normally but who have suffered damage to the brain's visual centre, is a real and not imagined phenomenon.
In tests, the blind have been able to distinguish basic shapes of objects they cannot see, as well as their orientation and direction of motion. On other occasions a blind person has reported experiencing a "feeling" that an object is present, while not being able to see it.
