| 英文摘要 | The method comprises a step of contactless optical measurement of the local value of at least one refringence optical characteristic of said lens over defined local zone around said measurement point of said lens, and at least one step of feeling said lens during which the axial position of said measurement point on one of the faces of the lens is determined; the axial position of the measurement point obtained by feeling is compared with the local value of the optical characteristic of the lens at the measurement point as determined from the contactless optical measurement, in order to deduce therefrom at least one vertex optical power of the lens at said measurement point. |
