Abstract:
1. A method, at least partly implemented by one or more computers, for providing a spectacle ophthalmic lens to a wearer, the method comprising: a) providing the wearer with an ophthalmic correction device so as to correct a low order (spherical and/or cylindrical) aberration of an eye of the wearer if said aberration is greater than 0.25 Diopter; b) measuring a visual acuity value of the eye of the wearer or a binocular visual acuity value of both eyes of the wearer where the eye of the wearer is substantially free of low order aberrations or is corrected according to step a); and c) calculating, using the one or more computers, a design of the spectacle ophthalmic lens or selecting a design in a spectacle ophthalmic lens design data base by adapting management of residual astigmatism based on the measured visual acuity value of step b), wherein the residual astigmatism is a difference between an astigmatism of the lens and a prescribed astigmatism corresponding to the aberration of the eye.
