1. A multi-piece insert device for an ophthalmic lens comprising:
an insert back curve piece;
an insert front curve piece;
a conductive material placed upon one or both of the insert front curve piece and the insert back curve piece;
an electronic component attached at least in part to the conductive material;
a self-locking feature including a groove on the insert front curve piece, a profile lip on the insert back curve piece configured to be pushed into the groove to fixedly hold the insert back curve piece in relative position to the insert front curve piece, thereby forming a cavity between the insert back curve piece and the insert front curve piece; and
a sealing feature provided within the groove of the insert front curve piece and in contact with the profile lip to form a seal around the cavity;
wherein the insertion of the profile lip into the groove compresses and maintains pressure on the sealing feature within the groove to form a seal around the cavity.
