• the store and the factory exchange necessary data such as the wearer's prescription information, the lens specifications to be applied, the frame shape, etc., to manufacture the desired eyeglass lenses.
• necessary data such as the wearer's prescription information, the lens specifications to be applied, the frame shape, etc.
• new data handling for the decoration process is required.
• data for decoration does not directly affect the main function of spectacle lenses, which is to correct refractive power, or other functions that ensure comfortable vision for the wearer, it creates new value for the product as an appearance function due to the decoration or display. Therefore, it is becoming recognized that it is extremely important to determine how to adapt decoration data to the known data handling involved in the manufacture of eyeglass lenses, and to obtain decorated lenses with excellent appearance performance and high shape and positional accuracy without compromising productivity.
• the present invention provides a technology that makes it possible to form a desired decorative pattern with high precision at an appropriate position on the optical surface of an optical component.
• the first aspect of the present invention is a method for producing a cellular membrane comprising the steps of: A method for manufacturing an optical member having a decorative pattern formed on an optical surface, comprising the steps of: obtaining shape data that specifies an outer shape of the optical component and design pattern data that specifies the decorative pattern to be disposed within the outer shape; A step of measuring a three-dimensional shape of a treated surface of a substrate that is a base of the optical member; a step of irradiating the treated surface of the base material with a laser beam in accordance with position control based on the design pattern data while performing focusing according to the measurement result of the three-dimensional shape, thereby forming the decorative pattern on the treated surface; and processing the outer shape of the base material in accordance with position control based on the shape data to make the base material have the outer shape of the optical member.
• the measurement of the three-dimensional shape of the base material, the formation of the decorative pattern, and the processing of the outer shape are performed while maintaining a base material supported by a jig block that supports the base material,
• This is a method for manufacturing an optical member, in which position control is performed when forming the decorative pattern and when processing the external shape, while corresponding a reference point set in a common coordinate system of the shape data and the design pattern data to a reference point of the jig block in the substrate supporting state.
• a second aspect of the present invention is a method for producing a composition
• a third aspect of the present invention is a method for producing a composition comprising the steps of: In the method for producing an optical member according to the first aspect, the laser beam is irradiated onto the surface to be treated via a telecentric optical system.
• a fourth aspect of the present invention is a method for producing a composition comprising the steps of: The method for producing an optical member according to any one of the first to third aspects, wherein the decorative pattern is formed by removing a part of a surface layer of the treatment surface by irradiating the treatment surface with the laser light.
• a fifth aspect of the present invention is a method for producing a composition comprising the steps of: The method for producing an optical member according to the fourth aspect, wherein the surface layer portion is constituted by an optical film having a multi-layer structure.
• a sixth aspect of the present invention is a method for producing a composition comprising the steps of: The method for producing an optical member according to the fourth aspect, wherein the decorative pattern is formed by non-heating processing using irradiation of a short pulse laser beam.
• the shape processing unit 28 After the laser processing unit 27c forms the decorative pattern 3 by irradiating the laser light, the shape processing unit 28 then performs edge processing (frame cutting processing) on the uncut lens 1 (S208). As a result, the outer shape of the uncut lens 1 is processed to become the outer shape 2 of a spectacle lens.
• the shape processing unit 28 also performs edge processing on the uncut lens 1 based on the shape data obtained by the data receiving unit 23. In other words, based on the shape data, the shape processing unit 28 performs edge processing on the uncut lens 1 according to position control based on the shape data, and the uncut lens 1 becomes the outer shape 2 of a spectacle lens.
• a reference point e.g., the boxing center
• the edging process by the shape processing unit 28 does not necessarily have to be performed after the formation of the decorative pattern 3 by the laser processing unit 27c, but may be performed prior to the formation of the decorative pattern 3 by the laser processing unit 27c. That is, in this specification, the step of forming the decorative pattern 3 and the step of edging the outer shape 2 mean that both steps are performed, regardless of whether they are performed in order. Therefore, in addition to the case where the step of edging the outer shape 2 is performed after the step of forming the decorative pattern 3, the case where the step of forming the decorative pattern 3 is performed after the step of edging the outer shape 2 is also included.
• the edging process is performed after the formation of the decorative pattern 3, lens cleaning between each process can be omitted, unlike the case where the decorative pattern 3 is formed after the edging process, which is preferable from the viewpoint of processing efficiency (productivity).
• a positional accuracy of the predetermined position (specifically, the relative positional accuracy of the decorative pattern 3 with respect to the outer shape 2) of, for example, a positional accuracy of ⁇ 500 ⁇ m or less, preferably a positional accuracy of ⁇ 100 ⁇ m or less, more preferably a positional accuracy of ⁇ 75 ⁇ m or less, and even more preferably a positional accuracy of ⁇ 50 ⁇ m or less.
• the processed uncut lens 1 i.e., the eyeglass lens having the decorative pattern 3
• the jig block 26 deblocking
• the removed eyeglass lens is then washed to remove any processing residue or adhering matter (foreign matter) as necessary, and a final lens appearance inspection is performed, after which the lens is inserted into an eyeglass frame selected by the eyeglass wearer (assembly of eyeglasses) (S211), completing the manufacture of the eyeglass lens.
• a reference point set in a common coordinate system of the shape data and the design pattern data is made to correspond to a reference point of the jig block 26 in a substrate supporting state, and position control is performed when forming the decorative pattern 3 and when edging the outer shape 2 of the eyeglass lens. Therefore, regardless of the shape of the outer shape 2 of the eyeglass lens, it is possible to place the decorative pattern 3 at an appropriate position on the optical surface of the eyeglass lens (specifically, a predetermined position within the range of the outer shape 2). Furthermore, in this embodiment, the uncut lens 1 supported by the jig block 26 is maintained in a supported state while the decorative pattern 3 is formed and the outer shape 2 is shaped.
• the three-dimensional shape of the treated surface of the uncut lens 1 supported by the jig block 26 is measured, and the laser light is irradiated while being focused according to the measurement result to form the decorative pattern 3. Therefore, it becomes possible to appropriately reflect the decorative pattern 3 on the treated surface (optical surface) of the uncut lens 1, which is a three-dimensional curved surface. As described above, according to this embodiment, even if the treated surface (optical surface) of the uncut lens 1 is a three-dimensional curved surface, it is possible to form the decorative pattern 3 with high precision at an appropriate position on the optical surface.
• the decorative pattern 3 when manufacturing the eyeglass lens, the decorative pattern 3 is positioned relative to the outer shape 2 of the eyeglass lens using a reference point set in a common coordinate system of the shape data and the design pattern data.
