Abstract

This invention is directed to a method of forming a patterned multi-piece insert for an ophthalmic lens. The method may include forming first insert front and back curve pieces. The method may further include depositing a conductive material onto one or both of the first insert front and back curve pieces and attaching an electronic component at least in part to the conductive material. The method may further include placing an adhesive material onto a surface of one or both of the first insert front and back curve pieces so that a first ophthalmic insert is sealed when the first insert front and back curve pieces are combined. The method may further include combining the first insert back and front curve pieces to form the first ophthalmic insert and applying a colorant to at least one surface of one or both of the first insert back and front curve pieces.

First claim

The invention claimed is:

1. A method of forming a patterned multi-piece insert for an ophthalmic lens, the method comprising:
forming a first insert back curve piece;
forming a first insert front curve piece;
depositing a conductive material onto one or both of the first insert front curve piece and first insert back curve piece;
attaching an electronic component at least in part to the conductive material;
placing an adhesive material onto a surface of one or both of the first insert front curve piece and first insert back curve piece so that a first ophthalmic insert is sealed when the first insert front and back curve pieces are combined;
combining the first insert back curve piece with the first insert front curve piece to form the first ophthalmic insert; and
applying a colorant to at least one surface of one or both of the first insert back curve piece and the first insert front curve piece.

2. The method of claim 1 , comprising applying the colorant by a lithographic imaging process.

3. The method of claim 1 , comprising applying the colorant after combining the first insert back curve piece with the first insert front curve piece to form the first ophthalmic insert.

4. The method of claim 3 , further comprising the step of curing the colorant.

5. The method of claim 1 , comprising applying the colorant to at least one surface of one or both of the first insert back curve piece and the first insert front curve piece before combining the first insert back curve piece and the first insert front curve piece to form the first ophthalmic insert.

6. The method of claim 5 , further comprising the step of curing the colorant.

7. The method of claim 1 , comprising applying the colorant by a pad printing process.

8. The method of claim 1 , comprising applying the colorant by an ink jet printing process.

9. The method of claim 1 , comprising applying the colorant by a screen printing process.
