| 摘要 |
The invention concerns a method comprising a step of contact-free optical measuring of the local value of at least one optical refraction characteristic of said lens on a local zone delimited about said measuring point of the lens, at least one step of tracing said lens during which the axial position of said measuring point on one of the sides of the lens is determined; combining the axial position of the measuring point obtained by tracing with the local value of the lens optical characteristic at the measuring point determined on the basis of the contact-free optical measurement, to deduce therefrom at least one front optical power of the lens in that measuring point. |
