Abstract

A lens ordering system includes: a computer, the computer being provided with a CPU, a storage unit, and a selection unit that is configured to be controlled by the CPU. The storage unit stores data, configured to enable determination of lens information that includes a resin material type, a pigment type, and a coating type that are used for a lens material, based on user information that includes basic information pertaining to a user, and at least one of usage information pertaining to lens usage desired by the user or psychosomatic information including psychosomatic symptoms and conditions including the eyes of the user. The selection unit determines and outputs the lens information based on the user information acquired pertaining to the user and the data stored in the storage unit.

First claim

The invention claimed is:

1. A lens ordering system, comprising:
a computer, the computer being provided with a CPU and a storage unit, and functioning as an acquisition unit and a selection unit that are configured to be controlled by the CPU, wherein:
the storage unit stores a learned model configured to output lens information of color lenses using user information as input,
the user information includes basic information about a user, usage information pertaining to lens usage regarding the use of the colored lens desired by the user, and psychosomatic information indicating symptoms and conditions of the body and mind of the user, including the eyes of the user,
the acquisition unit acquires at least one of usage information or psychosomatic information serving as the user information, via an input from a user, while transitioning through interface screens in a predetermined order, respectively,
the selection unit uses the user information acquired about the user as input to the learned model, determines the lens information based on the output from the learned model, and outputs it to a display unit,
the lens information includes a resin material type, a pigment type, and a coating type that are used for a lens material,
the lens information further includes information about lens staining properties, and information about resin solubility, which indicates the compatibility of a specific pigment with a specific resin,
the learned model is trained in advance by using, as learning data, weights for elements of the user information, and correct answer data for elements of the lens information,
in the case of acquiring the usage information, the usage information is acquired by firstly receiving a user selection of a usage type, and secondly receiving a user selection of details for a hierarchy of selection items provided for the selected usage type, and
in the case of acquiring the psychosomatic information, the psychosomatic information is acquired by firstly receiving a user selection of a symptom type, secondly receiving a user selection of a symptom area for the selected symptom type, and thirdly receiving a user selection of related symptoms.

2. The lens ordering system according to claim 1 , wherein:
the learned model that is trained is a learned model in which weighting parameters of a neural network model are defined for the elements of the user information and are learned by a deep learning technique the using, as learning data.

3. The lens ordering system according to claim 1 or 2 , wherein:
the computer further includes a collection unit,
the collection unit collects, via a network, the user information pertaining to the user, which is input to a terminal, and records the user information in the storage unit.

4. A lens ordering method that causes a computer to execute processing, the computer storing a learned model that is configured to output lens information for a colored lens using user information as an input, the user information including basic information about a user, usage information regarding the use of the colored lens desired by the user, and psychosomatic information indicating symptoms and condition of the body and mind of the user, including the eyes of the user, the processing comprising:
acquiring at least one of usage information or psychosomatic information by receiving user selections of selection items via input interface screens, in a predetermined order, respectively,
inputting the user information, including the at least one of the usage information and the psychosomatic information acquired, to the learned model, determining the lens information based on the output from the learned model, and outputting the lens information to a display unit,
the lens information including a resin material type, a pigment type, and a coating type that are used for a lens material,
wherein:
the lens information further includes information about lens staining properties, and information about resin solubility, which indicates the compatibility of a specific pigment with a specific resin,
the learned model is trained in advance by using, as learning data, weights for elements of the user information, and correct answer data for elements of the lens information,
in the case of acquiring the usage information, the usage information is acquired by firstly receiving a user selection of a usage type, and secondly receiving a user selection of details for a hierarchy of selection items provided for the selected usage type, and
in the case of acquiring the psychosomatic information, the psychosomatic information is acquired by firstly receiving a user selection of a symptom type, secondly receiving a user selection of a symptom area for the selected symptom type, and thirdly receiving a user selection of related symptoms.

5. A non-transitory computer-readable storage medium storing a program that causes a computer to execute processing, the computer storing a learned model that is configured to output lens information for a colored lens using user information as an input, the user information including basic information about a user, usage information regarding the use of the colored lens desired by the user, and psychosomatic information indicating symptoms and condition of the body and mind of the user, including the eyes of the user, the processing comprising:
acquiring at least one of usage information or psychosomatic information by receiving user selections of selection items via input interface screens, in a predetermined order, respectively,
inputting the user information, including the at least one of the usage information and the psychosomatic information acquired, to the learned model, determining the lens information based on the output from the learned model, and outputting the lens information to a display unit,
the lens information including a resin material type, a pigment type, and a coating type that are used for a lens material,
wherein:
the lens information further includes information about lens staining properties, and information about resin solubility, which indicates the compatibility of a specific pigment with a specific resin,
the learned model is trained in advance by using, as learning data, weights for elements of the user information, and correct answer data for elements of the lens information,
in the case of acquiring the usage information, the usage information is acquired by firstly receiving a user selection of a usage type, and secondly receiving a user selection of details for a hierarchy of selection items provided for the selected usage type, and
in the case of acquiring the psychosomatic information, the psychosomatic information is acquired by firstly receiving a user selection of a symptom type, secondly receiving a user selection of a symptom area for the selected symptom type, and thirdly receiving a user selection of related symptoms.

6. A non-transitory computer-readable storage medium storing a data structure that includes user information and that is used by a lens ordering system, the lens ordering system comprising a computer, the computer being provided with a CPU and a storage unit, and functioning as an acquisition unit and a selection unit that are configured to be controlled by the CPU
the storage unit stores a learned model configured to output lens information for a colored lens using user information as an input,
the data structure including the user information, wherein the user information includes basic information about a user, usage information regarding the use of the colored lens desired by the user, and psychosomatic information indicating symptoms and conditions of the body and mind of the user, including the eyes of the user,
