Method for manufacturing spectacle lens
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.
1. A method for manufacturing a spectacle lens, wherein
the spectacle lens includes
a lens substrate, which consists of a single member, the single member including a plurality of microprotrusions arranged on at least one surface of the lens substrate, the microprotrusions adjusting a refractive power of the spectacle lens, and
a coating film formed directly on the surface of the lens substrate that has the microprotrusions;
the microprotrusions are spherical protrusions which have a height of 0.1 μm to 10 μm and a radius of curvature of 50 mmR to 250 mmR; and
the method includes forming the coating film by applying an application liquid, through spin coating, directly to the surface of the lens substrate that has the microprotrusions.
2. The method for manufacturing a spectacle lens according to claim 1 , wherein the application liquid is a curable composition including a curable compound, and the method further includes performing a curing treatment of the curable compound after the application.
3. The method for manufacturing a spectacle lens according to claim 2 , wherein the curable composition has a viscosity in the range of 1 mPa·s to 50 mPa·s.
4. The method for manufacturing a spectacle lens according to claim 1 , wherein the spin coating is performed by supplying the application liquid from above to a surface having the microprotrusions that faces vertically upward during spinning.
5. The method for manufacturing a spectacle lens according to claim 1 , wherein the coating film has a thickness in a range of 0.5 μm to 100 μm.
6. The method for manufacturing a spectacle lens according to claim 1 , wherein the application liquid is a composition in which a resin component is dispersed in a solvent.
