A method of providing image information regarding primary eyewear to a remote production center where secondary eyewear is to be produced based thereon. The method comprises the steps of obtaining with an imaging device an image of the primary eyewear suitable for obtaining therefrom image data indicative of at least one geometric characteristic of the primary eyewear, providing to the production center reference data associated with the primary eyewear, and transmitting the image data via an external communication means to the production center for production there of the secondary eyewear based on the image and reference data. The reference data is representative of at least one reference dimension.
摘要:
A positioning system for use with a platform adapted to hold primary eyewear and an imaging device in mutual disposition and designed to arrange eyewear such that a front face thereof is at a predetermined orientation of an imaging device. The positioning system comprises an alignment device having an eyewear supporting portion and an alignment portion. The alignment portion is adapted to bear against the front face of the eyewear and, at least in use, positioned so as to impart the orientation to the eyewear. The predetermined orientation is preferably such that the front face is perpendicular to the optical axis of the imaging device.
