Abstract

An ophthalmic spectacle lens and a plurality of electronic components arranged in a form of at least one strip in contact with and along the periphery of the ophthalmic lens. An ophthalmic apparatus includes at least one frame and at least one ophthalmic device.

First claim

The invention claimed is:

1. An ophthalmic device comprising:
an ophthalmic spectacle lens comprising two main surfaces and an edge linking the two main surfaces; and
a plurality of electronic components arranged on a support forming a strip deposited in contact with and at a periphery on at least one of the main surfaces of the ophthalmic lens or on the edge of the ophthalmic lens, the plurality of electronic components being masked by a part of a frame configured to receive the ophthalmic device.

2. The ophthalmic device as claimed in claim 1 , wherein the edge of the ophthalmic lens comprises a groove in which the electronic components arranged in the form of a strip are disposed.

3. The ophthalmic device as claimed in claim 1 , wherein the length of the strip is greater than or equal to 10 times the width of the strip.

4. The ophthalmic device as claimed in claim 3 , wherein the length of the strip is greater than or equal to 50 times the width of the strip.

5. The ophthalmic device as claimed in claim 1 , wherein the ophthalmic lens has an electro-controlled functionality activatable in part or entirely by at least one of the electronic components arranged in the form of a strip.

6. The ophthalmic device as claimed in claim 1 , wherein the ophthalmic lens is an ophthalmic lens with phase variation and/or an ophthalmic lens with amplitude variation and/or an ophthalmic lens comprising at least one electro-controlled layer and/or a smart ophthalmic lens.

7. The ophthalmic device as claimed in claim 6 , wherein the ophthalmic lens is a lens with amplitude variation of an electrochromic ophthalmic lens, wherein the lens comprises two rigid parts linked together to form a cavity within which is arranged an electrochromic material, and wherein the plurality of electronic components arranged in the form of a strip are linked by an equipotential line to at least one of the rigid parts.

8. The ophthalmic device as claimed in claim 1 , wherein the electronic components arranged in the form of at least one strip are passive components and/or active components.

9. The ophthalmic device as claimed in claim 8 , wherein the electronic components arranged in the form of at least one strip are chosen from among a resistive component, a capacitive component, and/or among a diode, a radio component, an imaging device, a battery, a sensor, a motor.

10. The ophthalmic device as claimed in claim 1 , wherein the electronic components arranged in the form of at least one strip are linked together by at least one conducting wire and/or a conducting track configured to simultaneously convey electrical power and at least one signal relating to a piece of data.

11. The ophthalmic device as claimed in claim 1 , wherein the electronic components arranged in the form of a strip are deposited directly in contact with the ophthalmic lens.

12. An ophthalmic apparatus comprising at least one frame and at least one ophthalmic device as claimed in claim 1 .

13. The ophthalmic apparatus as claimed in claim 12 , wherein at least one strip comprising a plurality of electronic components is masked by a part of the frame.

14. An ophthalmic apparatus comprising:
at least one frame; and
at least one ophthalmic device, which comprises an ophthalmic spectacle lens and a plurality of electronic components arranged in a form of at least one strip in contact with and at a periphery of the ophthalmic lens,
wherein the electronic components arranged in the form of a strip are arranged on a support forming a strip and the support is deposited in contact with the ophthalmic lens, and wherein a part or the totality of the electronic components is masked by the frame.

15. A method for producing an ophthalmic device including an ophthalmic spectacle lens and a plurality of electronic components arranged in a form of at least one strip in contact with and at a periphery of the ophthalmic lens, the method comprising:
providing an unedged ophthalmic lens;
providing an edging contour for the ophthalmic lens;
providing a flexible strip comprising electronic components arranged on a support;
cutting the ophthalmic lens according to the edging contour to produce an edged ophthalmic lens;
fixing the flexible strip at the periphery of the edged ophthalmic lens.

16. A method for producing an ophthalmic apparatus which includes at least one frame and at least one ophthalmic device, which includes an ophthalmic spectacle lens and a plurality of electronic components arranged in a form of at least one flexible strip in contact with and at a periphery of the ophthalmic lens, the method comprising:
providing at least one flexible strip;
arranging the electronic components on the flexible strip;
providing at least one unedged ophthalmic lens;
providing at least one edging contour for the ophthalmic lens;
cutting at least the ophthalmic lens according to the edging contour to produce an edged ophthalmic lens;
fixing the flexible strip with the electronic components at a periphery of the edged ophthalmic lens;
fitting into place in the frame of the ophthalmic device comprising the edged ophthalmic lens and the flexible strip with the electronic components, such that a plurality of electronic components is in part or entirely masked by a part by the frame.
