Abstract

An emitter-detector pair sensor may be incorporated into a powered or electronic ophthalmic lens. The emitter-detector pair sensor may be configured to determine the distance from the sensor to an object in its path. Based upon this information, a system controller of the ophthalmic lens may output a signal to an actuator of the ophthalmic lens to control a variable power optic of the ophthalmic lens.

First claim

What is claimed is:

1. A powered ophthalmic lens, the powered ophthalmic lens comprising: a contact lens including an optic zone and a peripheral zone; and an emitter-detector pair sensor system incorporated into the peripheral zone of the contact lens, the emitter-detector pair sensor system comprising an emitter for sending out a signal, a detector for capturing a reflection of the signal, a controller operatively associated with the emitter and detector configured to determine the distance between the contact lens and an object and output a control signal based on the determined distance, and at least one actuator configured to receive the control signal and implement a predetermined function, the emitter comprising an LED chip having a size of up 150×150 microns and the detector comprising a CMOS semiconductor.

2. The powered ophthalmic lens according to claim 1 , wherein the contact lens comprises a variable-power optic incorporated into the optic zone.

3. The powered ophthalmic lens according to claim 2 , wherein the actuator configures the variable-power optic for either near or for distance vision in response to the determined distance.

4. The powered ophthalmic lens according to claim 1 , wherein the controller comprises a microcontroller and associated memory.

5. The powered ophthalmic lens according to claim 1 , further comprising a power supply.

6. The powered ophthalmic lens according to claim 5 , wherein the power supply comprises a battery.

7. A powered ophthalmic lens, the powered ophthalmic lens comprising: a contact lens; and an emitter-detector pair sensor system incorporated into the contact lens, the emitter-detector pair sensor system comprising an emitter for sending out a signal, a detector for capturing a reflection of the signal, a controller operatively associated with the emitter and detector configured to determine the distance between the contact lens and an object and output a control signal based on the determined distance, and at least one actuator configured to receive the control signal and implement a predetermined function, the emitter comprising an LED chip having a size of up 150×150 microns and the detector comprising a CMOS semiconductor photodiode.

8. The powered ophthalmic lens according to claim 7 , wherein the contact lens comprises a variable-power optic incorporated into the optic zone.

9. The powered ophthalmic lens according to claim 8 , wherein the actuator configures the variable-power optic for either near or for distance vision in response to the determined distance.

10. The powered ophthalmic lens according to claim 7 , wherein the controller comprises a microcontroller and associated memory.

11. The powered ophthalmic lens according to claim 7 , further comprising a power supply.

12. The powered ophthalmic lens according to claim 11 , wherein the power supply comprises a battery.

13. A powered ophthalmic lens, the powered ophthalmic lens comprising: an intraocular lens; and an emitter-detector pair sensor system incorporated into the intraocular lens, the emitter-detector pair sensor system comprising an emitter for sending out a signal, a detector for capturing a reflection of the signal, a controller operatively associated with the emitter and detector configured to determine the distance between the intraocular lens and an object and output a control signal based on the determined distance, and at least one actuator configured to receive the control signal and implement a predetermined function, the emitter comprising an LED chip having a size of up 150×150 microns and the detector comprising a CMOS semiconductor photodiode.
