Abstract: For surreptitiously stymieing a recognition of facial characteristics by a facial recognition system using a camera, a user wears an object in front of at least one eye, where the object includes a light displacer. The light displacer optically displaces light radially relative to the original light direction, but still parallel to the original light direction so that a view by the eye through the light displacer is not distorted. With the light displacer, there is an apparent position of the eye perceived by the camera which is shifted relative to other features of the face and relative to the actual position of the eye. Consequently, an image of the face obtained by the camera locates the eye at the apparent position which is substantially different from an image which would have been obtained with the actual position of the eye, so that the facial recognition system is stymied.
