Lens Product Description Standard

This standard addresses the need for an industry-wide data file structure and related terminology. It is for use by lens manufacturers and designers in describing the technical attributes of lens products. Suppliers of laboratory lens layout software use this data in the selection and processing of prescription lenses. Data describing the front surface geometry of non-spherical lenses is included to enable accurate control of lens thickness. Additional information required for the production of an individualized product design can be described through the inclusion of parameters. This standard replaces the many proprietary file formats currently in use when supplying software vendors with lens specifications in electronic form.
