Abstract: The invention relates to an ophthalmic device (1) satisfying a prescription for at least one power correction for a wearer, to a method for manufacturing it and to a use of a semi-finished hybrid ophthalmic lens.
The device comprises at least one electro-active cell (3) which comprises a rear shell (4) and a front shell (5) defining for the device a backside surface and an opposite front surface, the shells (4 and 5) being provided with transparent electrodes and delimiting a sealed cavity.
According to the invention, the rear shell (4) derives from a semi-finished hybrid ophthalmic lens comprising:
a front mineral part having a first mineral face proximal to the front shell (5) and a second mineral face opposite to the first mineral face, and
a rear plastic part attached to the front mineral part, the rear plastic part having a front plastic face bonded to said second mineral face and an unsurfaced rear plastic face which defines said backside surface and is configured to impart said prescription to the ophthalmic device, after surfacing said semi-finished hybrid ophthalmic lens.-

Abstract: A method and an optical system adapted for a wearer having an ophthalmic prescription. The optical system includes an optical device having a planar optical function, and an optical lens having an optical function based on the prescription of the wearer. The rear face of the optical device is attached to the front face of the optical lens, the optical device having at least one mechanical reference so as to allow an accurate relative position of the optical device and the optical lens.

Abstract: A method for superposing a first ophthalmic lens having a first face and a second ophthalmic lens having a second face in order to build an optical assembly delimited by the first and second faces. The method includes detecting respective positions in space and shapes of the first and second ophthalmic lenses, by using at least one sensor, detecting a first reference point on the first ophthalmic lens and a second reference point on the second ophthalmic lens, based on these respective positions in space and shapes, and modifying the respective positions so as to superpose the first and second reference points.

Abstract: Holding devices adapted for holding edged optical elements, manufacturing systems including such holding devices, and a corresponding method for manufacturing a compound optical element. The holding devices include a base for supporting a main surface of an edged optical element and either exactly three pegs or a plurality of clamps. The pegs are arranged so that two pegs are in contact with a first area of the side surface of an edged optical element positioned on the base while the remaining peg is in contact with a second area of the side surface only if a specific portion of the first or of the second area is within a specific position and orientation range about three perpendicular axes. The clamps are arranged to collectively hold an edged optical element positioned on the base by restricting its mobility with respect to three degrees of freedom.

Abstract: A device for pressing against each other a first ophthalmic lens having a first face and a second ophthalmic lens having a second face in order to build an electrochromic cell comprising a cavity delimited by the first and second faces, the first and second ophthalmic lenses being superposed and an adhesive substance being applied on at least one of the first and second faces to form the cavity, comprises the first and second ophthalmic lenses and at least one spring adapted to apply a pressure effort on the first and second ophthalmic lenses. It further comprises a programmable electric motor adapted to actuate said at least one spring and to control said pressure effort.
