Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a system for manufacturing order-made colored eyeglass lenses and an order-receiving system for colored eyeglass lenses.

[0002]

2. Description of the Related Art Conventionally, in a spectacle shop, when a customer orders a colored spectacle lens, it is usually performed as follows. That is, for example, a customer who has damaged one of the colored spectacle lenses in the spectacles brings the spectacles in which the other lens remains without being damaged to a spectacle shop as a color sample of the colored spectacle lens to be ordered. Then, the spectacle store sends the spectacle itself with the broken one lens to a lens manufacturer as a color sample, and the lens manufacturer uses a dye that has been color-mixed according to the color sample (the other non-damaged colored spectacle lens). The lens was stained. And
The finished colored spectacle lens was sent from the lens manufacturer to the spectacle store, where it was handed over to the customer.

Further, as described above, even if a customer breaks one of the colored spectacle lenses of the spectacles, if the customer orders at a spectacle shop where the spectacles were previously made, a color sample is used. Even if the spectacles are not brought in, if the color name of the colored spectacle lens (for example, 15% of Acute Brown) is clear, the spectacle store can inform the lens manufacturer of the color name. , Instead of sending color samples. Therefore, in this case, the mixing ratio of the dye to be used for dyeing the colored spectacle lens corresponding to the color name is checked from the data provided by the lens manufacturer, and the lens is dyed with the dye adjusted according to the data. Then, the finished colored spectacle lens is sent to the spectacle store and handed over to the customer in the same manner as described above.

[0004]

However, the above-described order manufacturing system (ordering system) has the following problems.

[0005] In other words, in the former case, the spectacle shop had to send to the lens manufacturer as a color sample for manufacturing spectacles with one lens damaged by a customer. Therefore, while the optician needs to send a color sample (glasses) to the lens manufacturer,
The lens manufacturer needs a procedure for receiving a color sample from an eyeglass store, which is problematic. In addition, when sending a color sample between an eyeglass shop and a lens manufacturer, it is necessary to use a method such as mailing, and there is a problem that a distribution cost is incurred.

In the latter case, the spectacle store informs the lens manufacturer of the color name of the colored spectacle lens,
Lens manufacturers dye colored spectacle lenses according to their color names. However, the other colored spectacle lens (the lens that is not damaged) of the spectacles owned by the customer may have a different color from that at the time of purchase due to fading due to aging. For this reason, even if the color name is the same, when the new colored eyeglass lens that is completed is fitted to the eyeglass frame, the colors are often slightly different between the left and right lenses, resulting in complaints from customers. There was a problem that it was easy.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and aims to reduce the complicated management work involved in ordering colored eyeglass lenses, and to prevent the occurrence of complaints from customers and reduce the total cost. The purpose is to achieve reduction.

Now, for example, if a customer breaks one of the colored spectacle lenses in the spectacles and brings the spectacle with the broken one of the lenses to the spectacle store 12 as a color sample,
At the spectacle store 12, the RGB color data is measured from the other color lens 20 (color sample) fitted without damage to the spectacles using the color discriminator 19 (B) shown in FIG. 2B. (Step (hereinafter abbreviated as "S") 1). That is, the color lens 20 (color sample) is placed on the placement table 25, the light from the light 27 is irradiated to the color lens 20, and the reflected light is photographed by the CCD camera 26. Then, the color discriminator 19 performs image processing to calculate RGB color data for the color lens 20. Then, from the color discriminator 19, the RG
When the B color data is transmitted to the ordering terminal 13, the CPU provided in the terminal 13 converts the RGB color data into color identification data (HSI color data) (S2).

Thereafter, the ordering terminal 13 transmits the converted color identification data (HSI color data) as color ordering data to the order receiving terminal 16 via the VAN 14 (S).
3). Then, the order receiving terminal 16 of the lens manufacturer 15
Receives the transmitted color identification data (S4).
Then, the order receiving terminal 16 stores the received color identification data in the memory and transmits the data to the color tone control terminal 17 and the lens color inspection terminal 18.

Accordingly, when the color-mixing control terminal 17 obtains the color-mixing ratio from the dye-mixing map based on each numerical value of the transmitted color identification data, it transmits the mixing data to the color-mixing machine 28. Then, in the color blender 28,
A dye for dyeing to be used for lens dyeing is prepared according to the preparation ratio shown in the preparation data (S6). And
Using the prepared dye for dyeing, a colorless lens (not shown) dyes the colorless lens (S7).

Next, the color inspection processing of the finished lens (stained colored eyeglass lens) will be described with reference to the flowchart of FIG. When the lens dyeing process in S7 is completed, the lens manufacturer 15 uses the lens color discriminator 29 shown in FIG. 2B to measure RGB color data of the completed lens (S11).
