Abstract
Official abstract text for this publication.
There is provided a method of producing a spectacle lens, wherein the spectacle lens has a water-repellent layer, and the method including film-forming the water-repellent layer by a heat deposition method and heating a plurality of deposition sources according to different temperature profiles in the film-forming by the heat deposition method, wherein, in the plurality of deposition sources, at least one deposition source contains a water-repellent component and at least one deposition source contains a metal component.
First claim
Opening claim text (preview).
1 . A method of producing a spectacle lens, wherein the spectacle lens has a water-repellent layer, the method comprising: film-forming the water-repellent layer by a heat deposition method; and heating a plurality of deposition sources according to different temperature profiles in the film-forming by the heat deposition method, wherein, in the plurality of deposition sources, at least one deposition source contains a water-repellent component, and at least one deposition source contains a metal component. 2 . The method of producing a spectacle lens according to claim 1 , wherein the metal component includes a silver-containing component. 3 . The method of producing a spectacle lens according to claim 2 , wherein the silver-containing component is silver particles. 4 . The method of producing a spectacle lens according to claim 1 , wherein the water-repellent component is a fluorine-containing component. 5 . The method of producing a spectacle lens according to claim 4 , wherein the fluorine-containing component is a fluorine-containing organic silane compound. 6 . The method of producing a spectacle lens according to claim 1 , wherein, in the different temperature profiles, one or more heating parameters selected from the group consisting of a temperature increase rate, a heating start time and a heating end time are different. 7 . The method of producing a spectacle lens according to claim 2 , wherein the plurality of deposition sources include a deposition source containing only one of the metal component and the water-repellent component. 8 . The method of producing a spectacle lens according to claim 7 , wherein the plurality of deposition sources include a deposition source containing only the metal component among the metal component and the water-repellent component, and a deposition source containing only the water-repellent component among the metal component and the water-repellent component. 9 . The method of producing a spectacle lens according to claim 2 , wherein the water-repellent component is a fluorine-containing component. 10 . The method of producing a spectacle lens according to claim 9 , wherein the fluorine-containing component is a fluorine-containing organic silane compound. 11 . The method of producing a spectacle lens according to claim 2 , wherein, in the different temperature profiles, one or more heating parameters selected from the group consisting of a temperature increase rate, a heating start time and a heating end time are different. 12 . The method of producing a spectacle lens according to claim 2 , wherein the plurality of deposition sources include a deposition source containing only one of the metal component and the water-repellent component. 13 . The method of producing a spectacle lens according to claim 12 , wherein the plurality of deposition sources include a deposition source containing only the metal component among the metal component and the water-repellent component, and a deposition source containing only the water-repellent component among the metal component and the water-repellent component. 14 . The method of producing a spectacle lens according to claim 3 , wherein the water-repellent component is a fluorine-containing component. 15 . The method of producing a spectacle lens according to claim 14 , wherein the fluorine-containing component is a fluorine-containing organic silane compound. 16 . The method of producing a spectacle lens according to claim 3 , wherein, in the different temperature profiles, one or more heating parameters selected from the group consisting of a temperature increase rate, a heating start time and a heating end time are different. 17 . The method of producing a spectacle lens according to claim 3 , wherein the plurality of deposition sources include a deposition source containing only one of the metal component and the water-repellent component. 18 . The method of producing a spectacle lens according to claim 12 , wherein the plurality of deposition sources include a deposition source containing only the metal component among the metal component and the water-repellent component, and a deposition source containing only the water-repellent component among the metal component and the water-repellent component. 19 . The method of producing a spectacle lens according to claim 4 , wherein the water-repellent component is a fluorine-containing component. 20 . The method of producing a spectacle lens according to claim 19 , wherein the fluorine-containing component is a fluorine-containing organic silane compound.
