Abstract: Patients suffering severe retinal damage and focusing impairment are examined in an area having actual or simulated outdoor illumination by viewing a large graphic having colored familiar objects, number and letters of graduated incremental sizes thereon with colored backgrounds either darker or lighter than the objects, numbers and letters involved which the patient points out to ascertain the patient's estimated optimal correction for distance vision. Based on said estimate, the patient is provided with a combination of a soft contact lens either between the estimated correction and a correction obtained by traditional testing methods using black letters against a white background in a darkened room, or the best correction obtained by the examination with the large graphic and a plurality of spectacle type lenses in incremental diopter corrections of two or three diopters for training purposes.

Abstract: A pair of non-prescription eyeglasses is mounted on a cantilevered support by a hanger that includes an element constructed of relatively stiff resilient plastic material. Such element includes a relatively wide main section having an aperture which receives the support arm, and a relatively narrow extension. The latter passes through the nose gap of the eyeglasses and is reversely bent to form a loop that surrounds the eyeglass frame bridge. In a first embodiment of this invention a rivet maintains the loop closed and prevents casual removal of the hanger from the eyeglasses. In a second embodiment a snap-type device holds the loop closed. This snap-type closure cannot be opened casually, at least for the first opening thereof.

Abstract: For three-dimensional viewing of television and movies, in the format wherein left-eye and right-eye images are presented alternately on the screen, a pair of 3-D viewing glasses have correspondingly alternating on/off left and right lenses. The lenses each contain liquid crystal material which varies from a nearly totally obscured state by scattering, to nearly 100% transmission, as controlled by a signal from the television or movie projector. In this way, in instances when the left-eye image is presented on the screen, the left-eye lens is "ON" so that the viewer sees the image with his left eye, and when the right-eye image is presented on the screen, the right-eye lens is "ON" to enable the viewer to see that image with his right eye. The two images on the screen are taken from different photographic angles, and the images alternate at a sufficient frequency for the viewer to perceive that both images are occurring at once, and he sees them as a composite three-dimensional image.

Abstract: Described is a device for testing for a perfect fit of spectacle frames on the head of the spectacle wearer. The device has at least one plate- or blade-shaped force or pressure sensor, which is mounted on a holder and can be applied to the respective contact surfaces between the frame and head.

Becausede of the negligible structural height of the pressure sensor, the individual contact areas between the frame and head can be tested without having to make any change in the controlled vane position in space existing when the spectacles are worn in place.
