Abstract
The method includes: automatic measurement of the marking characteristics of the lens in a measurement position in order to produce a marking reference of the ophthalmic lens; transfer of the lens in a second transfer movement from the measurement position to an intermediate position which is distinct from the measurement position; transfer of the lens in a third transfer movement from the intermediate position to a trimming position which is distinct from the intermediate position; locking of the ophthalmic lens on trimming elements (6); trimming the lens. The third transfer is carried out by third transfer elements that make up a sub-unit which is distinct and independent from other units or includes elements carrying out the second transfer, and trimming elements, wherein full blocking of the lens on the trimming elements is only completed after the third transfer.
