The invention relates to an ophthalmic lens having a main front face and a main rear face, one of said main faces comprising a filter that provides same with the following properties: an average reflection factor in the blue region over a wavelength range of 420 nm to 450 nm that is greater than or equal to 5% for an angle of incidence of between 0° and 15°; a spectral reflectivity curve for an angle of incidence of between 0° and 15°, said reflectivity curve having a maximum reflectivity at a wavelength less than 435 nm and a full-width at half maximum greater than or equal to 80 nm; and, for an angle of incidence &thetas; of between 0° and 15° and for an angle of incidence &thetas;' of between 30° and 45°, a parameter &Dgr;(&thetas;,&thetas;') defined by the relationship &Dgr;(&thetas;,&thetas;') = 1 - [ R |
