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.
