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.
