Abstract: A method of measuring lens shape of a spectacle lens, the method comprising: a) providing a spectacle lens on a surface; b) providing an image recording apparatus comprising a camera and a display; c) positioning the image recording apparatus so that the camera is largely parallel to the surface; d) capturing an image of the spectacle lens, the captured image comprising a total surface area of a camera-facing side of the spectacle lens; e) indicating positions of features of the spectacle lens in the captured image; and f) measuring a shape of the spectacle lens and determining image coordinates of the spectacle lens features.

Abstract: A method of measuring pantoscopic tilt of spectacles includes a) providing a spectacle frame comprising a spectacle frame front and temples; b) placing the spectacle frame on a user's face in a position of normal wear; c) providing an image recording apparatus which contains spatial orientation sensors; d) positioning the image recording apparatus to capture a side view image of the user wearing the spectacle frame; e) capturing an image of the user wearing the spectacle frame, wherein a profile of the spectacle frame front is visible, and recording spatial orientation data with the image recording apparatus; f) determining pantoscopic tilt of the spectacle frame.

Abstract: A method of measuring parameters for eyeglasses includes a) providing a frame comprising a left eye rim, a right eye rim, and a bridge joining the left eye rim to the right eye rim; b) capturing a first image of a user wearing the frame, wherein the first image captures the left eye rim and the bridge of the frame on the user; c) capturing a second image of the user wearing the frame, wherein the second image captures the right eye rim and the bridge of the frame on the user; d) scaling the first image using a known measurement; e) determining one or more left lens parameters; f) scaling the second image using a known measurement; and g) determining one or more right lens parameters.
