Abstract
Official abstract text for this publication.
There is provided a spectacle lens including a lens substrate and an inorganic layer, and further including a metal-containing layer on the side of the surface of the inorganic layer opposite to the lens substrate, wherein a metal contained in the metal-containing layer includes a first metal and a second metal, the first metal is silver, and the second metal is one or more metals selected from the group consisting of cobalt, nickel, zinc, copper, zirconium, molybdenum, lead, platinum, gold and palladium.
First claim
Opening claim text (preview).
1 . A spectacle lens, comprising a lens substrate and an inorganic layer, further comprising a metal-containing layer on the side of the surface of the inorganic layer opposite to the lens substrate, wherein a metal contained in the metal-containing layer includes a first metal and a second metal, wherein the first metal is silver, and wherein the second metal is one or more metals selected from the group consisting of cobalt, nickel, zinc, copper, zirconium, molybdenum, lead, platinum, gold and palladium. 2 . The spectacle lens according to claim 1 , wherein the second metal is one or more metals selected from the group consisting of zirconium, platinum, gold and palladium. 3 . The spectacle lens according to claim 1 , wherein the second metal includes platinum. 4 . The spectacle lens according to claim 1 , wherein the inorganic layer is a multilayer film composed of two or more inorganic layers. 5 . The spectacle lens according to claim 1 , wherein the metal-containing layer is a water-repellent layer. 6 . The spectacle lens according to claim 5 , wherein the water-repellent layer contains a fluorine-based organic compound. 7 . A method of producing the spectacle lens according to claim 1 , the method comprising: film-forming the metal-containing 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. 8 . The method of producing a spectacle lens according to claim 7 , 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. 9 . Spectacles comprising the spectacle lens according to claim 1 . 10 . The spectacle lens according to claim 2 , wherein the second metal includes platinum. 11 . The spectacle lens according to claim 2 , wherein the inorganic layer is a multilayer film composed of two or more inorganic layers. 12 . The spectacle lens according to claim 2 , wherein the metal-containing layer is a water-repellent layer. 13 . The spectacle lens according to claim 12 , wherein the water-repellent layer contains a fluorine-based organic compound. 14 . A method of producing the spectacle lens to claim 2 , the method comprising: film-forming the metal-containing 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. 15 . The method of producing a spectacle lens according to claim 14 , 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. 16 . Spectacles comprising the spectacle lens according to claim 2 . 17 . The spectacle lens according to claim 3 , wherein the inorganic layer is a multilayer film composed of two or more inorganic layers. 18 . The spectacle lens according to claim 3 , wherein the metal-containing layer is a water-repellent layer. 19 . The spectacle lens according to claim 18 , wherein the water-repellent layer contains a fluorine-based organic compound. 20 . A method of producing the spectacle lens according claim 3 , the method comprising: film-forming the metal-containing 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.
