There is provided a method for manufacturing a spectacle lens, including: preparing a lens substrate having a resin-containing hard coat film formed on at least one main surface; and forming a plurality of protuberances in which at least one of the lens substrate or the hard coat film is protruded, by irradiating the hard coat film with a laser.
Claims9
A method for manufacturing a spectacle lens, comprising:
- preparing a lens substrate having a resin-containing hard coat film formed on at least one main surface;
- and
- forming a plurality of protuberances in which the hard coat film is protruded, by irradiating the hard coat film with a laser, wherein the protuberances are formed due to local expanding of the hard coat film by laser irradiation.
A spectacle lens, comprising:
- a base portion where a light incident from an object-side surface is emitted from an eyeball side surface and converges on a retina through an eyeball;
- and
- a plurality of protuberances in contact with the base portion and having a property that light beams passing through at least a part of the protuberance are incident on the retina as a divergent light,
- the spectacle lens including a lens substrate and a hard coat film on the lens substrate, and
- the plurality of protuberances being the protuberances in which a surface of the hard coat film is protruded due to local expanding of the hard coat film.
