| 221 | Water sportsman's face mask for viewing objects above and below the line of vision | US539195 | 1990-06-18 | US5170190A | 1992-12-08 | Joseph J. Berke |
| A water sportsman's face mask for enabling a swimmer on or below the surface of a body of water to view objects which lie substantially above or below his normal line of vision without rotation of the swimmer's head or body. The mask comprises a frame, a lens mounted in the front of the frame, a flexible seal attached to the rear of the frame for forming a water-tight seal between the frame and the face of the swimmer, an adjustable strap for attaching the mask to the swimmer's head, and a pair of triangular prisms mounted on the lens which enable the swimmer to view objects above or below the swimmer's normal line of vision. One face of the prism is mirrorized and is in oblique relationship to the lens. In one embodiment of the invention the prisms are rotatably mounted to the frame and are selectively adjustable to a forward operative position and to a rearward inoperative position. | ||||||
| 222 | Ophthalmic prismatic image relocating eye glasses for persons having retinitis pigmentosa and hemianopia and method for making same | US410119 | 1989-09-20 | US5155508A | 1992-10-13 | Michael Onufryk |
| A pair of rotatable optical image deflector assemblies is disclosed which are detachably mounted via an adapter bracket to a conventional eye testing apparatus. Each optical image deflector assembly has a fixed light reflecting optical element, and a pivotal reflecting optical element. The optical image deflector assembly directs light onto a peripheral area of a visually sensitive or functional area of the retina which is normal to the central field of the retina. The pivotal optical element scans a pre-set field expanding test chart and projects an image thereof to the visually sensitive or functional area of the retina. The optical image deflector assembly is usable in making prismatic eye glasses to expand the normal central field of view of a person suffering from retinitis pigmentosa or hemianopia. The prismatic eye glasses refract images from a field outside the normal central field of view within and long the peripheral edge of the visually sensitive central area of the retina for expanding the normal central field of view. | ||||||

| 226 | Stereoscopic process and apparatus using different deviations of different colors | US470993 | 1990-01-22 | US5002364A | 1991-03-26 | Richard A. Steenblik |
| A method and apparatus for producing and viewing stereoscopic images through the use of a color coded image whereby the desired depth or distance is based upon the color of the portion of the image being viewed. Therefore the parts of the image which are to appear distant are colored red whereas the parts of the image to appear in the foreground are colored blue with the middle ground or intermediate distances being colored green or yellow. The color coded image is viewed through a prism glass constructed so that blue light which passes through the prism is bent toward a sharper angle than red light. Because the apex of the prism before each eye points toward the nose or center of the glasses the eyes must then turn more inward to see a blue object than to see a red object even though they are in actuality in the same plane on the display. This leads to brain to interpret, by means of parallax, that the blue image is closer and the red image is more distant unless the parallax is greatly contradicted by other depth clues such as relative size, position and perspective. In a preferred form, a double prism is used for each eye in order to eliminate single prism problems such as visual disorientation and eye strain. | ||||||

| 228 | Head movement indicating device and method | US410103 | 1989-09-20 | US4957295A | 1990-09-18 | Sam A. McConkey |
| An optical device is provided for determining the movement of the head of a user of the device relative to a fixed object that the user is viewing while performing a specific physical task. The optical device includes a pair of spectacles that are worn by the user. A flexible optical altering membrane substantially smaller than the lenses of the spectacles is adhesively secured to each lens of the spectacles in the area of the lens through which the user normally views the object. The optical altering membrane is selectively removable and reattachable to the spectacle lenses. The membrane causes the object to appear to the user to be in a first position when viewed through the optical altering membrane and to "jump" to a second position when viewed through portions of the spectacle lenses not covered by the membrane. | ||||||

| 232 | Forward-lens, lateral field reflector | US723504 | 1985-04-15 | US4733958A | 1988-03-29 | Robert E. Gorsich |
| A visual field image reflector attached to standard eyeglasses to extend vision into an impaired lateral visual field characteristic of a patient suffering from homonymous hemianopsia. The reflector is attached to the eyeglass frame adjacent the patient's nose, forward the lens for an eye having an impaired lateral field and displaced from the line of central fixation of gaze. The reflector includes a light-transmitting substrate and two differently tinted coatings. The first coating, near the patient's eye, is a partially-reflective and partially light-transmitting yellow tinted layer. The second coating, away from the patient's eye, is a light-transmitting, blue-violet layer. The reflected image of the lateral field is thus observed in yellow by the patient, and the portion of the central field image transmitted through the reflector is seen in blue-green. | ||||||
| 233 | Optical viewing accessory | US675352 | 1984-11-27 | US4647165A | 1987-03-03 | Stanley P. Lewis |
| An optical viewing system for use by bicycle riders and the like to increase the field of vision thereof includes headgear for supporting the system on the head of the user and an optical viewing accessory attached to the headgear. The optical viewing accessory has a pair of prisms thereon mounted for pivotal movement between retracted and extended positions. In their retracted positions, the prisms do not interfere with the direct line of sight of the user. However, in their extended positions, the prisms intersect the direct line of sight of the user and the internal reflection and refraction of the prisms allow the user to view objects located at positions at an angle, approximately ninety degrees, from the direct line of sight. The pivotal movement of the optical viewing accessory is activated under the influence of gravity as the head of the user is manipulated alternatively between the erect and prone positions. | ||||||
