Patent ID: 8543236

Claim:
A method for blocking an optical lens comprising: an orienting step in which the optical lens is oriented in a first reference position (P 1 ) and placed on a plurality of at least three pre-located pins which are vertically translated into a preset position (Z 1 , Z 2 , Z 3 ), so that, when the optical lens is placed on the plurality of at least three pre-located pins, the optical lens is oriented in the first reference position (P 1 ) where the vector perpendicular to the tangential plan at the prism reference point (PRP) of the optical lens corresponds to a desired vector (α f , β f , Z f ), a moving step in which the optical lens is moved from the first reference position (P 1 ) to a second reference position (P 2 ), so as to be in contact with a blocking material, the blocking material being in a molding block, the second reference position (P 2 ), being a function of the first reference position (P 1 ).
