Abstract

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.

Claims (14)

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,

wherein the film-forming the water-repellant layer by the heat deposition method comprises:

heating a first deposition source, which comprises a silver-containing component and a fluorine-containing water-repellent component, by a first heater, and

heating a second deposition source, which comprises a silver-containing component and a fluorine-containing water-repellent component, by a second heater, and

wherein a heating start time and a temperature increase rate of the first heater are different from a heating start time and a temperature increase rate of the second heater.

2 . The method of producing a spectacle lens according to claim 1 ,

wherein the silver-containing component of at least one of the first deposition source or the second deposition source is silver particles.

3 . The method of producing a spectacle lens according to claim 2 ,

wherein the fluorine-containing water-repellent component of at least one of the first deposition source or the second deposition source is a fluorine-containing organic silane compound.

4 . The method of producing a spectacle lens according to claim 1 ,

wherein the fluorine-containing water-repellent component of at least one of the first deposition source or the second deposition source is a fluorine-containing organic silane compound.
