Claims6
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.
