Abstract

This invention discloses various designs for rings that make up the functionalized layers in a functional layer insert. More specifically, design parameters for the rings for incorporation into an ophthalmic lens. Additionally, functional aspects of the rings and materials for encapsulating the functional insert into an area outside the optical zone of the ophthalmic lens.

Claims

1. An active lens insert for an ophthalmic lens comprising:

a stacked composite structure comprising;

annular shaped full ring substrate layers with one or both of electrical and logical functionality; and

electrical interconnections between the annular shaped full ring substrate layers to create the active lens insert;

wherein each of the annular shaped full ring substrate layers have a different radius and encircle an optical zone of the ophthalmic lens; and

wherein a size and a stacking structure of the annular shaped full ring substrate layers are selected to allow encapsulation of the active lens insert in a region around an optical zone of the ophthalmic lens.

2. The active lens insert of claim 1, wherein the annular shaped full ring substrate layers are adhered to insulating layers forming the stacked composite structure.

3. The active lens insert of claim 1, wherein the annular shaped full ring substrate layers are cut from a wafer.

4. The active lens insert of claim 1, wherein the size and the stacking structure for the annular shaped full ring substrate layers is further based on a base curve of the ophthalmic lens.

5. The active lens insert of claim 1, wherein the size and the stacking structure for the annular shaped full ring substrate layers is further based on a diameter of the ophthalmic lens.

6. The active lens insert of claim 1, wherein the size and the stacking structure for the annular shaped full ring substrate layers is further based on encapsulation parameters of the ophthalmic lens.

7. The active lens insert of claim 1, wherein the active lens insert comprises at least three annular shaped full ring substrate layers.

8. The active lens insert of claim 1, wherein the active lens insert comprises a full ring annular shape.

9. The active lens insert of claim 7, wherein at least one of the annular shaped full ring substrate layers comprises a metallic layer configured to act as an antenna.

10. The active lens insert of claim 7, wherein at least one of the annular shaped full ring substrate layers of the active lens insert comprises an energization source.

11. The active lens insert of claim 7, wherein at least one of the annular shaped full ring substrate layers of the active lens insert comprises a power regulation source.

12. The active lens insert of claim 11, wherein the power regulation source comprises at least one semiconductor layer with electronic microcircuitry capable to control electric current flow from electrochemical cells.

13. The active lens insert of claim 12, wherein the electronic microcircuitry is electrically connected to an electroactive lens component within the ophthalmic lens.

14. The active lens insert of claim 12, wherein the power regulation source is capable of receiving power from external sources.

15. The active lens insert of claim 12, wherein the power regulation source is capable of charging a battery layer.

16. The active lens insert of claim 12, wherein the power regulation source is capable of controlling the use of power when the ophthalmic lens is not in a charging environment.

17. The active lens insert of claim 12, wherein the power regulation source is capable of controlling the use of power when the ophthalmic lens is in a charging environment.

18. The active lens insert of claim 12, wherein at least one of the annular shaped full ring substrate layers of the active lens insert comprises a solid state energy source.

19. The active lens insert of claim 1, wherein at least one of the annular shaped full ring substrate layers comprises microcircuitry to detect actuation signals for the active lens insert.
