Abstract:
The invention concerns an ophthalmic lens ( 1 ) that comprises a substrate ( 2 ) having a front main face ( 3 ) and a rear main face ( 4 ) and a photonic crystal layer ( 5 ) at least partially covering one of said main faces, and that has a spectral reflectivity curve for an incident angle on the front main face of between 0° and 45°, having a reflectivity peak with a maximum reflectivity value at a peak wavelength of between 420 and 450 nanometers, and a chroma value on reflection by the front main face with an incident angle of between 0° and 45° that is less than 30. The invention also concerns a method for producing such an ophthalmic lens.

Claim (Index 31):
A process for manufacturing an ophthalmic lens, including the following steps:\n a\u2032) depositing an initial layer of a solution containing a solvent and a composition containing colloidal particles in suspension in a matrix on at least one of the front and back main faces of a substrate of the ophthalmic lens; b\u2032) at least partially evaporating the solvent from the initial layer deposited on said main face so that the colloidal particles arrange themselves in said matrix to form an intermediate photonic crystal layer; and c\u2032) solidifying the matrix of the intermediate layer; wherein the composition implemented in step a\u2032) is such that the ophthalmic lens has\n a curve of spectral reflectivity for an angle of incidence on said front main face comprised between 0\u00b0 and 45\u00b0 that comprises a reflectivity peak having a maximum reflectivity value at a peak wavelength comprised between 420 and 450 nanometers; and \n a chroma value (C) in reflection from said front main face with an angle of incidence comprised between 0\u00b0 and 45\u00b0 that is lower than 30.
