Abstract

Described embodiments include a vision system and a method. A vision system includes a receiver circuit configured to receive data indicative of a presence of a wearable ophthalmic element in an optical path incident on a vision correction device. The vision correction device includes an electronically controllable vision parameter and configured to be placed in an eye of a human subject. The vision system includes a controller circuit coupled to the vision correction device and configured to change the electronically controllable vision parameter of the vision correction device at least partially in response to the received data indicative of the presence of the wearable ophthalmic element in the optical path.

First claim

The invention claimed is:

1. A vision correction system comprising:
a receiver circuit configured to receive data indicative of a presence of a wearable ophthalmic element in an optical path incident on a vision correction device, the vision correction device including an electronically controllable vision parameter and configured to be implanted in an eye of a human subject, wherein the vision correction device is configured to operate without the ophthalmic element and to adapt to the presence of the ophthalmic element being in the optical path; and
a controller circuit coupled to the vision correction device and configured to change the electronically controllable vision parameter of the vision correction device at least partially in response to the received data indicative of the presence of the wearable ophthalmic element in the optical path, operation of the vision correction device being adjusted to account for the presence of the wearable ophthalmic element in the optical path as determined by the receiver circuit responsive to the electronically controllable vision parameter being changed by the controller circuit.

2. The system of claim 1 , wherein the receiver circuit is carried by the vision correction device.

3. The system of claim 1 , wherein the data includes human-inputted data indicative of the presence of the wearable ophthalmic element in the optical path.

4. The system of claim 1 , wherein the data includes a data signal indicative of the presence of the wearable ophthalmic element in the optical path.

5. The system of claim 4 , wherein the data signal is originated by an electronic device associated with the wearable ophthalmic element.

6. The system of claim 4 , wherein the data signal includes a radiofrequency band data signal, an ultrasound frequency band data signal, or an optical frequency band data signal.

7. The system of claim 4 , wherein the data signal is transmitted by a sensor circuit configured to detect the presence of a wearable ophthalmic element in the optical path incident on the vision correction device.

8. The system of claim 1 , wherein the data includes data indicative of a focal length, optical transmissivity, or an identification of the wearable ophthalmic element of the wearable ophthalmic element.

9. The system of claim 1 , wherein the controller circuit is configured to correct a refractive error in the eye by changing the electronically controllable vision parameter of the vision correction device at least partially in response to the received data indicative of the presence of the wearable ophthalmic element in the optical path.

10. The system of claim 1 , wherein the controller circuit is configured to not change the vision parameter of the vision correction device responsive to an override signal.

11. The system of claim 1 , further comprising:
a transmitter circuit configured to broadcast data indicative of the presence of the wearable ophthalmic element in the optical path.

12. The system of claim 1 , further comprising:
a wearable structure configured to position or support the wearable ophthalmic element in the optical path incident on the vision correction device; and
a transmitter circuit carried by the wearable structure and configured to broadcast data indicative of the presence of the wearable ophthalmic element in the optical path.

13. The system of claim 1 , further comprising:
a wearable structure configured to position or support the wearable ophthalmic element in the optical path incident on the vision correction device; and
a human-interface circuit coupled to the wearable structure and configured to (i) receive a human-input indicative of a presence of the wearable ophthalmic element in the optical path, and (ii) broadcast data indicative of the presence of the wearable ophthalmic element in the optical path.

14. The system of claim 1 , further comprising:
a sensor circuit configured to detect and transmit data indicative of the presence of the wearable ophthalmic element in the optical path.

15. The system of claim 1 , further comprising:
a correction manager circuit configured to search an electronic database for a specified focal length of the wearable ophthalmic element.

16. The system of claim 15 , wherein the controller circuit includes a controller circuit coupled to the vision correction device and configured to change a vision parameter of the vision correction device at least partially in response to the specified focal length of the wearable ophthalmic element.

17. The system of claim 1 , further comprising:
a database stored on a non-transitory computer readable storage media and specifying a respective focal length of the wearable ophthalmic element for at least two identified wearable ophthalmic elements.

18. The system of claim 1 , wherein the wearable ophthalmic element includes an eyeglass lens.

19. The system of claim 1 , wherein the wearable ophthalmic element includes a contact lens.

20. A method of vision correction, the method comprising:
receiving data, by a receiving circuit, indicative of a presence of a wearable ophthalmic element in an optical path incident on a vision correction device implanted in an eye of a human subject, wherein the vision correction device is configured to operate without the ophthalmic element and to adapt to the presence of the ophthalmic element being in the optical path; and
changing, by a controller circuit, an electronically controllable vision parameter of the vision correction device at least partially in response to the received data indicative of the presence of the wearable ophthalmic element in the optical path.

21. The method of claim 20 , further comprising:
broadcasting the data indicative of the presence of the wearable ophthalmic element in the optical path incident.

22. The method of claim 20 , further comprising:
receiving a human-input indicative of the presence of the wearable ophthalmic element in the optical path; and
broadcasting data indicative of the presence of the wearable ophthalmic element in the optical path.

23. The method of claim 20 , further comprising:
searching an electronic database for a specified focal length of the vision correction device correcting a refractive error in the eye if a particular identified wearable ophthalmic element is present in the optical path; and
changing a vision parameter of the vision correction device at least partially in response to the specified focal length of the vision correction device.

24. A vision correction system comprising:
