A method of forming a multi-piece insert for an ophthalmic lens, the method comprising:
- forming at least a first insert back curve piece;
- forming at least a first insert front curve piece;
- depositing a conductive material onto one or both of the first insert front curve piece and the first insert back curve piece;
- attaching an electronic component to one or both of the first insert front curve piece and the first insert back curve pieces, wherein the attachment is made to the conductive material;
- placing a first material to form a first seal upon a surface of either or both of the first insert front curve piece and the first insert back curve piece;
- and
- combining the first insert back curve piece with the first insert front curve piece to form a first ophthalmic insert piece, wherein the combining causes the first material to seal a first cavity interior to the combination of the first back curve piece and the first front curve piece.
