Abstract

A method of controlling a programmable lens device comprising a programmable lens and an optical function controller, the programmable lens having an optical function and extending between at least one eye of the wearer and the real world scene when the device is used by the wearer, and the optical function controller being arranged to control the optical function of the programmable lens, the method comprising: an optical function data receiving step during which optical function data relating to the optical function of the programmable lens is received by the optical function controller, an optical function modifying step during which the optical function of the programmable electronic lens device is modified by the optical function controller based on the optical function data.

Claims

1. A method of controlling a programmable lens device comprising a programmable lens and an optical function controller, the programmable lens having an optical function and extending between at least one eye of a wearer and a real world scene when the programmable lens device is used by the wearer, and the optical function controller being arranged to control the optical function of the programmable lens, the method comprising:

an initializing step during which the optical function of the programmable lens device is initialized based on user data comprising at least the wearer'"'"'s ophthalmic prescription;

an optical function data receiving step during which optical function data relating to the optical function of the programmable lens is received by the optical function controller; and

an optical function modifying step during which the optical function of the programmable lens is modified by the optical function controller based on the optical function data.

2. The method according to claim 1, wherein the optical function data comprise a computer program adapted to be executed by the optical function controller and during the optical function modifying step the computer program is executed by the optical function controller so as to modify the optical function of the programmable optical lens.

3. The method according to claim 1, wherein the optical function data comprise at least dioptric function data relating to a dioptric function based at least on an ophthalmic correction adapted to the wearer.

4. The method according to claim 3, wherein the dioptric function data relate a progressive multifocal optical design.

5. The method according to claim 1, wherein the method further comprises:

a viewing condition data receiving step during which viewing condition data relating to the viewing condition of the wearer are received by the optical function controller; and

wherein during the optical function modifying step the optical function is modified based on the viewing condition data.

6. The method according to claim 5, wherein the viewing conditions comprise a sighting distance of the wearer.

7. The method according to claim 5, wherein the viewing conditions comprise a proximity of objects in the wearer'"'"'s environment.

8. The method according to claim 5, wherein the viewing conditions comprise a luminosity of the wearer'"'"'s environment.

9. The method according to claim 5, wherein the viewing conditions comprise elements relating to a posture of the wearer.

10. The method according to claim 5, wherein the method further comprises:

an activity data receiving step during which activity data relating to the activity of the wearer are received by the optical function controller; and

wherein during the optical function modifying step the optical function is modified based on the activity data.

11. The method according to claim 5, wherein the device further comprises:

a visual information display device arranged to display visual information over the real world scene viewed by the wearer through the programmable lens when the programmable lens device is used by the wearer; and

a visual information display controller arranged to electronically control the display of the visual information; and

wherein the method further comprises a display modifying step during which the displayed information is adapted based on at least one of the viewing condition data, user data, the activity data, and the optical function data.

12. The method according to claim 5, wherein the optical function data are received from a distant entity.

13. The method according to claim 12, wherein at least one of the viewing condition data, activity data, and user data are sent to the distant entity and the optical function data are adapted based on said data.

14. The method according to claim 1, wherein the user data further comprise at least one of morphologic data relating to a morphology of a head of the wearer, viewing strategy data relating to a viewing strategy of the wearer, lens usage, and wearer preferences.

15. A network system comprising at least a programmable lens device and a distant entity, the programmable lens device and the distant entity being configured so as to enable communication between the programmable lens device and the distant entity, and the distant entity configured to store at least one computer program product comprising one or more stored sequences of instructions that when executed by an optical function controller of the programmable lens device, causes the optical function controller being operable to:

adapt an optical function at least according to a user'"'"'s ophthalmic prescription;

receive optical function data relating to an optical function of the programmable lens device; and

modify the optical function of the programmable lens device, and wherein the distant entity is further configured to store dioptric function data that when used by the optical function controller of the programmable lens device, causes the optical function controller to adapt the optical function at least according to the user'"'"'s ophthalmic prescription.

16. A computer program product comprising one or more stored sequences of instructions that are accessible to an optical function controller of a programmable lens device, and which, when executed by the optical function controller, causes the optical function controller to adapt an optical function of the programmable lens device to an ophthalmic prescription;

receive optical function data relating to an optical function of the programmable lens device; and

modify the optical function of the programmable lens device.
