Abstract:
The invention relates to a method for determining an usage index value for an single-vision ophthalmic lens adapted to correct the vision of a myopic wearer. According to the invention the method comprises: an optical profile providing step S 1  during which an optical profile of said ophthalmic lens is determined; a material profile providing step S 2  during which a material profile of said ophthalmic lens is determined; a physical parameter determining step S 3  during which at least one physical parameter among physical parameters of said optical profile and material profile is determined; a gain assessing step S 4  during which at least two gains brought by at least one determined physical parameter is evaluated on at least one evaluation criterion of dissatisfaction of said wearer when wearing said ophthalmic lens; an usage index value determining step S 5  during which a value of an usage index is determined by adding the assessed gain for the evaluation criteria.

Claim (Index 4):
A method for assisting the choice of an ophthalmic lens by a wearer, said wearer being initially provided with a first pair of glasses comprising a first ophthalmic lens, said wearer wishing to replace said first ophthalmic lens with a second ophthalmic lens, wherein the method comprises:\n determining a value of a first usage index; determining at least one second usage index; providing an ophthalmic lens comprising supplying the second ophthalmic lens to the wearer, where the value of said second usage index is greater than the value of said first usage index; wherein determining a value of the first usage index comprises:\n determining a first optical profile of said first ophthalmic lens; \n determining a first material profile of said first ophthalmic lens; \n determining at least one first physical parameter among physical parameters of said first optical profile and first material profile; \n comprising evaluating at least two first gains brought by at least one determined first physical parameter on at least one first evaluation criterion of dissatisfaction of said wearer when wearing said first ophthalmic lens; and \n determining a value of a first usage index by adding the assessed first gain for the first evaluation criteria; \n wherein determining a value of the second usage index comprises:\n determining a second optical profile of said second ophthalmic lens; \n determining a second material profile of said second ophthalmic lens; \n determining at least one second physical parameter among physical parameters of said second optical profile and first material profile; \n comprising evaluating at least two second gains brought by at least one determined second physical parameter on at least one second evaluation criterion of dissatisfaction of said wearer when wearing said second ophthalmic lens; and \n determining a value of a second usage index by adding the assessed second gain for the second evaluation criteria.
