scope:

This International Standard establishes a method by which machines and computer software systems used in the fabrication of ophthalmic lenses can exchange information. The International Standard defined herein provides: a method by which machines and computer systems conduct their exchanges of data; a method by which computer systems can initialize such parameters on machines as the manufacturers thereof allow; a method by which machines can initialize computer systems with information that the systems can use for various purposes; a method by which a machine can inform a computer system as to what information it wants to receive, thus allowing machines to define new interfaces dynamically; a standard set of records and device types that are used to communicate agreed upon sets of information. The last feature listed above requires that this International Standard be amended on a regular basis, as the need for new data elements is inevitable.
