Abstract: A method of determining eyeglass frame parameters from a digital image of the person's face and a digital image of an eyeglass frame. The method comprises the steps of: (a) providing a digital image of the person's face; (b) determining a physical scale of the face using a scaling factor; (c) locating center points P1, P2 of the left and right irises in the face image, and determining a pupil midpoint Pc; (d) providing a digital image of an eyeglass frame; (e) adjusting, if necessary, the size of the frame to the physical scale of the face; (f) combining the frame and face images such that the frame is superimposed on the face; (g) aligning the frame and face in accordance with the frame center point fc and the pupil midpoint Pc; and (h) determining the frame parameters.

Abstract: An eyeglass frame selecting system in which the eyeglass lens picture can be synthesized with the eyeglass frame image and the customer's facial image so that the effect for the eyeglass lens based on the lens prescription value of the customer can be known, is provided. The eyeglass frame selecting system comprises a keyboard 3 for inputting the prescription value data of an eyeglass lens and a lens mold contour data based on the refraction property of a customer's objective eye, and an operation control circuit 1b for synthesizing the eyeglass lens image based on the prescription value of the lens inputted by the keyboard 3 and a facial image 20 with the eyeglass frame image L through a picture synthesizing circuit 10 to display the synthesized image on a display device 8.

Abstract: An interactive eyewear selection system comprising: a video camera and digitizing system for acquiring a digital image of a person's face, including the temple areas of the face; an eyeglass frames database for storing digital eyeglass frame images; an automated interface for selecting an eyeglass frame image from the frames database, the image containing frame temple portions; a digital processing system for automatically superimposing the selected frame image on the image of the person's face, in a composite image, such that the frame appears to be worn naturally on the person's face and the frame temple portions are shown at the temple areas of the face; and a display device for displaying the digital image of the person's face and for displaying the composite image.

Abstract: A head mounted lens support for performing examination and photography of the posterior structures of the eye. The support includes a lateral support to which a pair of adjustable earpieces, and an adjustable nosebridge are attached. Right and left lens positioners are moveably and pivotable attached to the lateral support. The lens positioners each are adjustable by lateral positioners, depth positioners, and angle positioners. The angle positioners swivel from their nominal positions, perpendicular to the lateral support, through an arc of approximately 25 degrees in order to allow full examination of the structures in the posterior chamber of the eye. Right and left lens cradles are attached, respectively, to the ends of the right and left angle positioners. The lens cradles are forms of arc clamps which receive a lens sleeve. The lens sleeve is itself an arc clamp which contains the actual lens.

Abstract: A method is provided for custom manufacturing or fitting eyeglasses wherein a digital camera is used to take a series of digital images of selected portions of a subjects head, the images then being stored in a computer electronically associated with the camera, wherein the images contain frame and lens fitting information with respect to the size and shape of the subjects head, and thereafter providing a visual image display screen functionally associated with the computer for receiving and visually displaying the images such that an eyeglass frame and lens can be structurally and dimensionally configured in accordance with the fitting information.

Abstract: An ophthalmic lens holder for holding lenses in a tinting bath has an upright support with oppositely directed base channels and spring loaded pivoted clamping arms over the base channels. Lenses are held side by side between the clamping arms and the base channels. The holder is designed to facilitate insertion and viewing of the lenses.

Abstract: This invention will for the first time provide a digital read-out showing the amount of diopters either Positive or Negative with a zero starting point midway between the Positive and Negative dioxter readings. The people having their eyes checked will now be able to communicate in the most accurate way with their eye doctor using an adjustment knob for each eye respectively to obtain the prescription needed. This is achieved through a specially designed lens unit and through the use of direct gear rack drives attached to the movable lenses coupled to an encoder and that is battery powered producing a DC square wave output voltage and fed into a Positive to Negative read-out display Totalizer unit with LED electronic digital read-out that is available with a scaling factor for precise conversion to diopter values for each eye respectively. The Totalizer is a computerized unit with microchip circuitry running on DC battery current which makes the Vari-Lens.TM.

Abstract: An eyeglass testing device is provided with independent side-to-side positioning of left and right lenses and independent side-to-side and front-to-back positioning of a separate set of front left and right test lenses on a platform attached with universal adjustment to a head harness and worn by a patient while being tested for vision assistance.

Abstract: A trial frame is disclosed presenting pairs of lens holders on one or both sides of a common beam for ocular therapy and testing by a plurality of test lenses. Each lens frame holder is grooved to simultaneously accommodate plural lenses and may completely or partially encircle lenses to releasably hold them. Secured at each lateral extremity of the common beam is an elastic head band to quickly and securely position the test frame for use especially as on an active younger child.

Abstract: A pair of trial spectacles for allowing a wearer to test the feeling and effect of a pair of spectacles and lenses before an actual pair is constructed. The trial spectacles include a frame member adapted to be supported on the face of a wearer having at least a first eye rim portion positioned in front of one of the eyes of wearer when the frame member is supported on the face of the wearer. The first rim portion is adapted to removably support a first lens. The first lens is horizontally slidable in the first portion so that the first lens can be horizontally adjusted to meet the wearer's visual requirements.

Abstract: Eye glasses for experimentation and testing comprising a frame on which adjustable lens holders can be shifted.They comprise a frontal mounting 1 which is extended downwardly in its central portion in the direction of the patient's nose by a bar 5 of short length and on which glides a vertically adjustable support 6 for engagement with the patient's nose or his regular eye glasses which the patient has to wear during the testing.Application of the eye glasses for allowing tests to be taken with a patient who has to get new glasses with different corrective lenses and different positions of said lenses with respect to the eyes of the patient.

Abstract: A lens holder having a pair of spring connected clamping members with apertures therein mountable over a lens socket of spectacle frames. The clamping members have an extent which is sufficient to completely span lens sockets and extend a distance beyond. Transverse lateral rulings on at least one of the clamping members permit gauging an aperture in a clamping member relative to a socket in a spectacle frame. In this manner, geometrical characteristics of a test lens may be measured and recorded for the purpose of making permanent lenses for a selected spectacle frame. In addition to transverse lateral rulings on a clamping member, angular rulings about an aperture in a clamping member may also be applied for determining angular orientations of a test lens.
