Abstract:
1. A remote method for measuring a pupillary distance taking into account relevant physiognomy and a desired frame of an individual, comprising: providing a calibration frame with at least one known measurement between two identified points, wherein the calibration frame is dimensioned and configured substantially the same as the desired frame, wherein the calibration frame provides two eye-frames joined at a nose-bridge, and wherein each eye-frame defines a periphery of a lens; capturing a photographed image of the calibrated frame with a co-planar imaging device at a predetermined distance from the individual's left and right eye, wherein the calibrated frame is being comfortably worn by the individual; determining a scale factor of the photographed image by comparing the at least one known measurement to an apparent distance between the two identified points captured on the photographed image; and calculating a horizontal distance between a first portion of each eye and a center of the nose-bridge by scaling each apparent horizontal distance captured on the photographed image by the scale factor of the image.
