Method implemented by computer means for determining the most appropriate lens design for a wearer for the purpose of providing a lens to the wearer, the method comprising: - a level of acceptance determination step S22 during which the levels of acceptance of the user for multiple lens designs are determined according to a method comprising: o a notation table receiving step S6 during which a notation table of the user is received, the notation table corresponding to a set of subjective values representing the sensitivity of the user to a set of optical aberrations; o a notation table associating step S10 during which the notation table of the user is associated to a lens design based on the set of optical aberrations; and o a level of acceptance determining step S12 during which the level of acceptance of the user for the lens design is determined based on the association of the notation table of the user and the lens design; - a comparison step S26 during which the levels of acceptance of the multiple lens designs are compared together; and - a lens design determining step S28 during which the most appropriate lens design for the wearer is determined, characterized in that the method further comprises prior to the notation table associating step, a zone defining step S8 during which zones are defined on a lens design map, and wherein the notation table associating step and the level of acceptance determining step are carried out for each defined zone; and comprising prior to the comparison step S26 a zone defining step S23 during which zones corresponding to each level of acceptance are defined on the design maps and a level of satisfaction determining step S24 during which a level of satisfaction is determined. - a level of acceptance determination step S22 during which the levels of acceptance of the user for multiple lens designs are determined according to a method comprising: o a notation table receiving step S6 during which a notation table of the user is received, the notation table corresponding to a set of subjective values representing the sensitivity of the user to a set of optical aberrations; o a notation table associating step S10 during which the notation table of the user is associated to a lens design based on the set of optical aberrations; and o a level of acceptance determining step S12 during which the level of acceptance of the user for the lens design is determined based on the association of the notation table of the user and the lens design; o a notation table receiving step S6 during which a notation table of the user is received, the notation table corresponding to a set of subjective values representing the sensitivity of the user to a set of optical aberrations; o a notation table associating step S10 during which the notation table of the user is associated to a lens design based on the set of optical aberrations; and o a level of acceptance determining step S12 during which the level of acceptance of the user for the lens design is determined based on the association of the notation table of the user and the lens design; - a comparison step S26 during which the levels of acceptance of the multiple lens designs are compared together; and - a lens design determining step S28 during which the most appropriate lens design for the wearer is determined, the method further comprises prior to the notation table associating step, a zone defining step S8 during which zones are defined on a lens design map, and wherein the notation table associating step and the level of acceptance determining step are carried out for each defined zone; and comprising prior to the comparison step S26 a zone defining step S23 during which zones corresponding to each level of acceptance are defined on the design maps and a level of satisfaction determining step S24 during which a level of satisfaction is determined.
