Abstract
A method includes a step of contactless optical measurement of the local value of at least one refringence optical characteristic of the lens over defined local zone around the measurement point of the lens, and at least one step of determining the axial position of the measurement point on one of the faces of the lens; the axial position of the measurement point obtained 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 the measurement point.
