Claim:
The process of functionalizing an optical lens by a conforming apparatus for conforming a functionalized flexible planar film onto an optical lens, characterized in that it comprises: a module comprising a mechanical piston and a plate mounted above said mechanical piston; said piston being capable of presenting a vertical translational movement along the axis (y), within said module; a mechanical anti-return device for said piston capable of blocking the plate at a determined height on the inside of the module; a lens-holder positioned on the top face of the plate, comprising a holding device for an optical lens; a film carrier capable of holding a flat flexible film, said film carrier comprising a holding device making it possible to position and locking said film carrier on the module at its upper end (Ia), the locking involving the hermetic closure of said module; a stamp situated vertical to the module; electrical, pneumatic or mechanical translation devices connecting said stamp to a support shaft, said devices being capable of effecting controlled vertical and/or horizontal movements of the stamp; actuation of the stamp, the piston, the translation devices, according to a predetermined sequence and governed by an automatic device makes it possible to establish the contact between the stamp, the flexible planar film and the optical lens until obtaining a conformal contact between said optical lens and said film, wherein said process comprises the following steps: a) contact with the stamp and the planar film under the action of the translation devices and preforming of said film by the application of a mechanical force up to a threshold P 1 or a position threshold Z 1 controlled by a force sensor and/or position sensor, wherein the force threshold P 1 is between 1 N and 200 N; b) activation of the piston in the module involving an ascending vertical translational movement at a speed of VO of the optical lens up to initiation of the contact between the preformed film and said lens; c) maintenance of the ascending vertical translation of the optical lens by the action of the piston until attaining the target force threshold P 2 or the position threshold Z 2 controlled by the force sensor and/or the position sensor involving the propagation and establishment of the conformal contact between the face of the lens to be treated and the film; d) maintenance of the lens/film conformal contact during a temporization time t 2 ; e) ascending vertical translation of the stamp at a speed V 2 ; f) interruption of the pressure applied to the piston; and g) opening of the module.
