Abstract

A contact lens blister package 1 includes (i) a cavity 4 for storing a contact lens 20 and (ii) charging circuitry 3 configured to charge an electronic device 22 forming part of a contact lens 20 stored in said cavity 4. Related methods are also described.

First claim

The invention claimed is:

1. A contact lens blister package for storage of contact lenses prior to first use of the lens, the package comprising (i) a cavity for storing a contact lens and (ii) charging circuitry configured to charge an electronic device forming part of a contact lens stored in said cavity, wherein the charging circuitry comprises a power source that is a battery or other element arranged to retain an electrical charge and wherein the charging circuitry comprises a switch arranged to control the operation of the charging circuitry, wherein the package is a blister package for storage of contact lenses prior to first use of the lens, and wherein the switch comprises a detachable portion arranged such that detaching said portion from the blister pack initiates charging of the electronic device.

2. The contact lens blister package according to claim 1 , wherein the power source is a battery and the charging circuitry includes a DC/AC inverter arranged to turn direct current from the battery into alternating current.

3. The contact lens blister package according to claim 1 , wherein the charging circuitry is configured to charge the electronic device wirelessly.

4. The contact lens blister package according to claim 3 , wherein the charging circuitry includes a first induction coil arranged to receive current from a power source and to provide power wirelessly to the electronic device.

5. The contact lens blister package according to claim 4 , wherein the first induction coil extends around at least a portion of the perimeter of the cavity.

6. The contact lens blister package according to claim 4 , wherein the electronic device includes a second induction coil electromagnetically coupled to the first induction coil, the first and second induction coils preferably having the same resonant frequency.

7. The contact lens blister package according to claim 1 , wherein the blister package includes a base member, wherein the base member includes at least part of the charging circuitry.

8. The contact lens blister package according to claim 1 , wherein the blister package includes a sealing member, wherein the sealing member includes at least part of the charging circuitry.

9. The contact lens blister package according to claim 1 , wherein the blister package further comprises a contact lens including an electronic device being located within the cavity.

10. A method of providing a charge to an electronic device contained within a contact lens, the method comprising sealing the contact lens into a blister package, to obtain the contact lens bluster package of claim 2 .

11. The method according to claim 10 , wherein the charging circuitry comprises a power source, and the method comprises charging the power source after the contact lens has been sealed into the blister package.

12. The method according to claim 11 , wherein said charging the power source takes place more than one month after the blister package is sealed.

13. The method according to claim 10 , wherein the method comprises activating the charging circuitry in order to charge the electronic device.

14. The method according to claim 13 , wherein said activating the charging circuitry takes place more than one month after charging the power source.

15. A method of manufacturing a packaged electronic contact lens, the method comprising placing the contact lens, containing one or more electronic components, in a cavity of a blister pack comprising charging circuitry configured to charge the electronic device, and then sealing the blister pack with the contact lens contained within the cavity.

16. An array of contact lens blister packages, said array comprising two or more contact lens blister packages coupled together, wherein each of the two or more contact lens blister packages are for storage of a single contact lens prior to first use of the lens, and comprising (i) a cavity for storing a contact lens and (ii) charging circuitry configured to charge an electronic device forming part of a contact lens stored in said cavity, wherein the charging circuitry comprises a power source that is a battery or other element arranged to retain an electrical charge and wherein the charging circuitry comprises a switch arranged to control the operation of the charging circuitry, and wherein the switch comprises a detachable portion arranged such that detaching said portion from the blister pack initiates charging of the electronic device.
