19 Claims

1. A method for manufacturing a spectacle lens, the spectacle lens having a lens substrate and at least one coating, the method comprising at least:

providing a lens substrate having an uncoated or precoated front surface and an uncoated or precoated back surface;

applying at least one coating to at least one of the surfaces of the lens substrate, partially or completely;

contacting the at least one surface of the at least one coating, partially or completely, with at least one medium; and

obtaining the spectacle lens having the lens substrate and the at least one coating, the surface of the at least one coating being modified,

wherein the modification of the surface of the at least one coating is a diffusion-controlled surface modification resulting in a swelling of the at least one coating, and wherein the modification of the surface of the at least one coating is considering an individual peripheral refraction of at least one wearer's eye.
