Abstract: Method implemented by computer means for determining an ophthalmic lens adapted to a wearer and to a spectacle frame, the method comprising: providing wearer data comprising the wearer's ophthalmic prescription, providing mounting data comprising at least the tie points of the ophthalmic lens to be mounted in the spectacle frame, providing thickness requirement data comprising the minimum thickness of the ophthalmic lens at the tie points, determining ophthalmic lens data based on the wearer data, the ophthalmic lens data comprising the two optical surfaces of the ophthalmic lens and their relative positions, an oversize creating step (S5), during which the ophthalmic lens determined during the ophthalmic lens data determining step is locally thickened by creating an oversize at the tie points, so that the thickness of the ophthalmic lens at the tie points is greater than or equal to the minimum thickness.
