Abstract: A system and method for determining the measurements needed to fabricate prescription eyeglasses. A person is scanned with a time-of-flight scanner while wearing the eyeglass frames. This produces depth maps from known distances. Common measurement points are identified within at least some of the scans. The positional changes of the common measurement points and the known distance to the imaging camera are utilized to map three dimensional coordinates for the measurement points using an actual measurement scale. Fabrication measurements are calculated between the various three-dimensional coordinates in the same scale.

Abstract: A method of obtaining ophthalmic measurements. An individual wears frames. Control simulations are performed to determine an average far gaze view line, average intermediate gaze view line, and average near gaze view line. The average far gaze view line intersects the lens plane at a second intersection point. The average intermediate gaze view line intersects the lens plane at a third intersection point. The average near gaze view line intersects the lens plane at a fourth intersection point. The far region extends from a first position above the first intersection point to a second position below the second intersection point. The intermediate region extends from the second position to a third position below the third intersection point. The near region extends from the third position to a fourth position below the fourth intersection point. The control simulation takes into account the height and stature to fit the natural viewing dynamic.

Abstract: A system and method for determining the measurements needed to correctly fabricate prescription eyewear for an individual who is purchasing the eyewear. The individual is provided with an initial set of frames. The initial set of frames is fitted to the requirements of the individual to obtain a fitted frame. An eye exam is also conducted to obtain a proper lens prescription for the fitted frames. The individual is imaged while the fitted frames are being worn. This creates reference images. At some point, the individual may select a subsequent set of frames. Once the subsequent set of frames is selected, a retailer recalls the reference images and obtains fitting measurements from the reference images. The online retailer can also recall the lens prescription for the initial fitted frames. Utilizing the fitting measurements, the retailer can custom fit the subsequent set of frames.

Abstract: A system and method for determining the measurements needed to fabricate prescription eyeglasses. A person is imaged wearing the eyeglass frames, from a first camera position and a subsequent camera position. This produces images having differing perspectives from known distances. Common measurement points are identified within at least some of the images. The common measurement points undergo positional changes between the images having said differing perspectives. The positional changes of the common measurement points and the known distance to the imaging camera are utilized to map three dimensional coordinates for the measurement points using an actual measurement scale. Fabrication measurements are calculated between the various three-dimensional coordinates in the same scale.

Abstract: A system and method for determining the measurements needed to fabricate prescription eyeglasses. The system and method take into account how the frames fit naturally on the head and how the person's posture orients the head and alters the line of sight through the lens of the eyeglasses. A sensor unit is provided that is attached to the eyeglass frames. The individual then wears the eyeglass frames and moves through at least one situational simulation. The sensor unit generates data that corresponds to changes in orientation. The data is used to determine how a person's line of sight is altered by the anatomy of the face and the posture of the head.
