METHOD FOR STORING INFORMATION ON A SPECTACLES LENS, SPECTACLES LENS BLANK OR SPECTACLES LENS SEMI-FINISHED PRODUCT

摘要

Information is stored in an optical element in the form of a glass or plastic body embodied as spectacles lens, spectacles lens blank or spectacles lens semi-finished product. The information in the form of data is stored on or in the glass or plastic body by creating at least one marking with a marking system. The marking can be read by a reading apparatus. The marking system has an interface for reading information individualizing the optical element. The marking is created permanently by the marking system on or in the optical element at a definition point of a local body-specific coordinate system set by two points on or in the optical element. In this body coordinate system, the manufacturer specifies the position of the lens horizontal and/or the far and/or the near and/or the prism reference point.

1. A method of storing information on a glass or plastic body defining a spectacle lens or a spectacle lens blank or a semi-finished product, said glass or plastic body having a local body specific coordinate system defining a definition point and said coordinate system being set by two points on or in said glass or plastic body with said coordinate system being for the manufacture-side specification of the position of at least one of the following: lens horizontal, far reference point, near reference point and prism reference point as defined by standard regulations set forth in DIN EN ISO 8980-2:2004, the method comprising the steps of:
storing said information in the form of data in or on the glass or plastic body by producing a permanent marking with a marking apparatus in or on said glass or plastic body at said definition point and configuring said marking to permit a reading thereof by a reading apparatus; and, using an interface of said marking apparatus to read in information individualizing said glass or plastic body.
