Definitions
- the present invention relates to a system and a method for processing incoming orders and manufacturing spectacle lenses.
- the manufacturing process of a spectacle lens from the determination of the ametropia of a spectacle lens user to the manufacture of the actual spectacle lens is today, due to the large number of different lens types, materials, customization options, etc., very complex.
- the systems and processes used have a high degree of decentralization and are highly interdependent.
- An example of a conventional distributed system and method is described in WO 2017/102003 A1.
- a first aspect of the invention relates to a system for incoming order processing of at least one spectacle lens, such as a system for incoming order processing of a spectacle lens, a pair of spectacle lenses or a large number (for example a batch) of spectacle lenses.
- the system comprises: a receiving unit for receiving order data for at least one spectacle lens, with a catalog of spectacle lens classes being stored in the receiving unit which are each defined by a fixed number of predetermined and freely selectable order parameters and differ from one another in the number of freely selectable order parameters, the receiving unit being configured to classify the order data using the catalog of spectacle lens classes, and one Processing unit for processing the order data, wherein only the highest lens classes of the catalog of lens classes are stored in the processing unit, wherein the processing unit is configured to select one of the highest lens classes, to adapt the order data to the selected highest lens class and a respective to generate a digital image of the at least one spectacle lens using a calculation model and the customized order data, and include a communication device which connects the receiving unit and the processing unit or which is designed
- the system according to the first aspect of the invention makes it possible for orders for spectacle lenses to be processed more easily and with less effort, ie more cost-effectively and with less resource consumption.
- Resources means, in particular, the storage space for the incoming order processing of the data relevant to the spectacle lenses, such as different classes of spectacle lenses.
- the system according to the first aspect of the invention has a minimum of decentralization, so that the maintenance of the system is designed to be more efficient, in particular simpler.
- the system according to the first aspect of the invention comprises the two units: receiving unit and processing unit, each of which has a signal connection with one another.
- the receiving unit and processing unit are connected via a communication device which enables the exchange of data (for example via a communication network).
- the communication device may include, for example, a communication network (network).
- the data can, for example, be exchanged via the communication device using XML, JSON or another suitable format or can be transmitted from one unit to another.
- the units can also communicate via the communication device (such as via the network) by Remote Procedure calls communicate with each other.
- the ordering parameters of the lenses or the glasses of the glasses to correct the ametropia are conventionally determined by an optician and/or with the aid of a machine.
- the order parameters here include, for example, the product designation and the refraction values, such as sphere (in dioptres) and/or cylinder (in dioptres), the axis position and/or the prism (amount and base) for the distance and/or the near and/or an addition and/or data from the trial glasses used to determine the refraction values for the distance and/or the near, such as the position in front of the eye and the optical effect of the trial lenses used.
- the ordering parameters can also be individual parameters of the spectacle wearer and/or the usage position of the spectacles and/or the geometric shape of the spectacle frame and/or the centering and/or parameters for controlling the design variants and/or the use of the spectacles and/or the product design and/or services and/or biometric characteristics of the eye or eyes of the prospective glasses wearer, etc.
- Exemplary individual parameters are the frame lens angle, the tilt, the pupillary distance, the corneal vertex distance, etc.
- Exemplary product designs are lens coloring, lens tinting, lens coatings, etc.
- Exemplary services include taking out insurance for the glasses or financing, whether the lenses on the specified frame should be rounded, whether the lenses should be centered in the specified glasses, etc.
- Biometric properties that describe the eye are for example. Wavefront errors including higher orders (e.g. as Zemike coefficient set), pupil sizes and/or positions at different viewing directions, eye length, curvatures and positions of the refracting surfaces of the eye, refractive index of the media, etc..
- order parameters After the order parameters have been determined, they are transmitted to the system according to the first aspect of the invention and received or received by the receiving unit in the form of order data.
- the receiving unit classifies the order data received using the catalog of spectacle lens classes stored in the receiving unit.
- the catalog can be stored, for example, in the form of a computer-readable list.
- the spectacle lens classes differ in the quantity or number of ordering parameters that can be freely selected and/or customized and are taken into account when calculating the spectacle lens.
- the spectacle lens classes can reflect different levels of customization of the spectacle lens.
- a spectacle lens class can thus be defined in particular by the subset of freely selectable and/or individualizable order parameters.
- a higher class of spectacle lenses can be defined, for example, by a larger subset of freely selectable and/or customizable order parameters than a lower class of spectacle lenses.
- the freely selectable and/or customizable order parameters assigned to each spectacle lens class can also be stored in the catalog (for example in the form of a list).
- a first (the lowest) lens class can only contain refraction values or refraction parameters, such as sphere and/or cylinder with axis position and/or prism with axis position.
- a second, higher class of spectacle lenses can also contain other individual parameters of the spectacle wearer and/or the position of use, such as interpupillary distance, corneal vertex distance, frame lens angle, frame shape, etc.
- a third, even higher class of spectacle lenses can also contain further individualization parameters, such as biometric properties of the eye, etc., in addition to the individual parameters mentioned above.
- the division into spectacle lens classes for single-vision spectacle lenses or multifocal spectacle lenses can be carried out in a similar way to the division into spectacle lens classes for progressive lenses.
- a first spectacle lens class can only contain refraction values or refraction parameters, such as a sphere and/or cylinder with an axis position and/or a prism with an axis position and/or addition.
- a higher class of spectacle lens can also contain other individual parameters of the spectacle wearer and/or the position of use, such as pupillary distance, corneal vertex distance, frame lens angle, frame shape, etc.
- An even higher lens class can be added to the previous ones mentioned individual parameters also further individualization parameters, such as parameters for controlling the design variants and/or biometric properties of the eye and/or the use of the glasses, etc., contain.
- a first spectacle lens class can also only contain refraction values or refraction parameters, such as addition, sphere and/or cylinder with axis position and/or prism with axis position.
- a higher class of spectacle lenses can also contain other individual parameters of the spectacle wearer and/or the position of use, such as pupillary distance, corneal vertex distance, frame lens angle, frame shape, etc.
- an even higher class of spectacle lenses can also contain further individualization parameters, such as use of the spectacles and/or biometric properties of the eye, etc.
- the receiving unit can check whether the transmitted order data contain the parameters of a spectacle lens class to be selected and classify the order data accordingly in a spectacle lens class.
- the classification can also be based on other ordering parameters.
- the receiving unit can be configured to classify and clean up the order data if the order data contain parameters determined by the catalog of spectacle lens classes that are not permitted for at least one spectacle lens.
- the order data can be cleaned up, for example by removing the parameters that are not permitted.
- Parameters that are not permitted can be, for example, parameters that are not permitted, cannot be selected, or cannot be customized for a specific ordered lens class.
- An example of impermissible order parameters are individual parameters (such as pupillary distance, corneal vertex distance, etc.) for a non-individual product. Other examples are certain glass materials and/or coatings.
- this embodiment makes it possible to reduce memory consumption and data traffic in the system.
- the receiving unit then transfers the classified order data to the processing unit via the communication device.
- Only the highest spectacle lens classes for example the highest spectacle lens classes for one of different product categories, such as single vision, varifocal, multifocal, near comfort lenses, etc., are stored in the processing unit.
- the highest lens class (for a specific product category) is the British lens class with the largest number of order parameters to be specified (e.g. freely selectable or customizable).
- the processing unit adapts the classified order data to one of the highest spectacle lens classes if the classified order data corresponds to a lower spectacle lens class.
- the processing unit can adapt the order data that has been assigned to a spectacle lens class to the selected highest spectacle lens class by filling in the parameters of the highest spectacle lens class that are not specified in the ordered spectacle lens class with standard values or by adding the missing order parameters of the highest spectacle lens class to the ordered spectacle lens class and the default values for the missing parameters are extended.
- this embodiment makes it possible that within the processing unit for a number of spectacle lens classes only one highest spectacle lens class and possibly the parameters necessary for expanding the ordering data have to be created.
- the possibly adjusted order data is then processed in such a way that the processing unit generates a digital image of the ordered spectacle lens on the basis of this order data.
- the digital image can be a simulation of the spectacle lens and/or a theoretical spectacle lens, for example.
- the processing unit accesses a calculation model that can be filed or stored in the processing unit. The processing unit thus processes the received and classified order data.
- the receiving unit and the processing unit may each have their own data storage.
- the receiving unit and the processing unit are preferably units that operate independently of one another.
- this embodiment allows the system to have a low level of complexity and a low degree of decentralization, thereby simplifying maintenance and testing of the system.

- the parameters can be, for example, the contour of the boundary of the blank, the front and rear surfaces and their position and orientation in relation to one another, and the blank material.
- the merchandise management system can also carry out a pre-selection of the production, in particular the production means, based on, for example, production parameters and/or utilization indicators.
- the processing of certain glass geometries, materials and/or layers may not be possible in old production locations, so that production, in particular the production location and/or or the tooling, can be preselected (step S35).
- the parameters from the calculation can be the average curvature and/or the maximum curvature and/or the minimum curvature of the surface to be produced and its orientation to the base curve, for example determined by the angle of rotation.
- the parameters can include, for example, the shape of the lens contour.
