Abstract
A method for providing a spectacle ophthalmic lens to a wearer, the method comprising the following consecutive steps: measuring the visual acuity value(s), VA, of the eye(s) of the wearer or the binocular visual acuity value, VAbino, of both eyes of the wearer where the eye(s) of the wearer is (are) substantially free of low order aberrations or is (are) corrected of low order aberrations; calculating thanks to computer means a design of the spectacle ophthalmic lens or selecting a design in a spectacle ophthalmic lens design data base by adapting the management of residual astigmatism based on the measured visual acuity value(s) of the eye(s) of the wearer.
