Abstract
Disclosed is a method implemented by a computer, for determining the position of an optical lens member having a surface placed on a lens blocking ring, the blocking ring including a bearing zone arranged to bear at least partially a placed known surface of the optical lens member when the known surface of the optical lens member is placed on the lens blocking ring and hold by a force applied on the optical lens member, the method includes finding a trio of points of the bearing zone that forms a triangle including the projection on the main plane of the point of application of the force; and a position of the optical lens having a virtual contact between the placed known surface and the ring at the location of the trios of points.
