Abstract: Provided is an eyeglass lens configured to cause rays that have entered from an object-side surface to be emitted from an eyeball-side surface and cause the emitted rays to converge at a predetermined position A. The eyeglass lens includes a lens base material having a plurality of base material convex portions on at least one of the object-side surface and the eyeball-side surface, and the eyeglass lens has a configuration for suppressing stray light rays that do not pass through the vicinity of the predetermined position A or the vicinity of the position B that is closer to the object than the predetermined position A is.

Abstract: Provided is an eyeglass lens 1 configured to cause rays that have entered from an object-side surface 3 to be emitted from an eyeball-side surface 4, and cause the emitted rays to converge at a predetermined position A. The eyeglass lens 1 includes a lens base material 2 having a plurality of base material convex portions 6 on at least one of the object-side surface 3 and the eyeball-side surface 4, and a coating film covering the surface provided with the base material convex portions 6. The shape of convex portions present on the outermost surface of the eyeglass lens located on a side on which the base material convex portions 6 are provided is an approximate shape of the base material convex portions configured to cause rays that have entered the eyeglass lens 1 to converge at a position B that is closer to the object than the predetermined position A is.

Abstract: Provided is a method for manufacturing a spectacle lens, wherein: the spectacle lens includes a lens substrate having microprotrusions on at least one surface, and a coating film formed on the surface of the lens substrate that has the microprotrusions; and the method includes forming the coating film by applying an application liquid, through spin-coating, to the surface of the lens substrate that has the microprotrusions.

Abstract: A lens holding jig (3) includes a lower holding portion (15) that holds the lower surface of a lens base material (1). The upper surface of the lower holding portion (15) forms support surfaces (16) that support the lower edges (S1, S2) of a cut end surface (1a) of the lens base material (1) at two points. An application liquid release portion (17) running downward is provided at the center of the support surfaces (16). The application liquid release portion (17) is formed from a long hole, a long groove, or a projection.

Abstract: A method for manufacturing an optical member by vapor depositing an antireflective film on a plastic optical member and vapor depositing a water-repellent thin film over the antireflective film. The vapor deposition of the water-repellent thin film is conducted by evaporating a fluorine-containing organic silicon compound in which the plastic optical member does not exceed the maximum temperature during the vapor deposition of the antireflective film. The heating for evaporation comprises a first stage where the temperature is raised from an ordinary temperature to the prescribed temperature (1) not exceeding the starting temperature of vapor deposition of the compound, and the second stage where the temperature is raised from the prescribed temperature (1) to the prescribed temperature (2) equal to or higher than the starting temperature of the vapor deposition. The rate of raising temperature of the first stage of raising temperature is higher than that of the second stage.
