Abstract

A system can include a display configured to emit light rays; an adjustable-prescription optics overlay; and circuitry to adjust the adjustable-prescription optics overlay to a selected prescription to alter a focus of light rays emitted by at least a portion of the display. Various other apparatuses, systems, methods, etc., are also disclosed.

Claims

1. A system comprising:

a display that emits light rays;

an adjustable-prescription optics overlay; and

circuitry that adjusts the adjustable-prescription optics overlay to a selected prescription to alter a focus of light rays emitted by at least a portion of the display wherein an adjustment to the adjustable-prescription optics overlay by the circuitry depends at least in part on a lens prescription parameter.

2. The system of claim 1 wherein the adjustable-prescription optics overlay is configured to form a Fresnel lens.

3. The system of claim 1 wherein the adjustable-prescription optics overlay comprises a fluidic network.

4. The system of claim 3 wherein the circuitry to adjust is configured to control fluid pressure in the fluidic network.

5. The system of claim 1 wherein the adjustable-prescription optics overlay comprises liquid crystal material.

6. The system of claim 5 comprising compartments that comprise at least a portion of the liquid crystal material.

7. The system of claim 1 wherein the adjustable-prescription optics overlay comprises a ferromagnetic fluid.

8. The system of claim 1 wherein the adjustable-prescription optics overlay comprises rings.

9. The system of claim 8 wherein the rings are adjustable to form a Fresnel zone.

10. The system of claim 1 wherein the adjustable-prescription optics overlay comprises features configured to form circular optical structures and configured to form annular optical structures.

11. The system of claim 10 wherein the adjustable-prescription optics overlay comprises features configured to form a circular optical structure surrounded by a plurality of annular optical structures.

12. The system of claim 1 comprising sensing circuitry to sense distance between the display and an object.

13. The system of claim 12 wherein the circuitry to adjust comprises a distance parameter wherein an adjustment to the adjustable-prescription optics overlay by the circuitry depends at least in part on the distance parameter.

14. The system of claim 1 comprising detection circuitry to detect eye squinting.

15. The system of claim 14 wherein the circuitry to adjust comprises an eye squinting parameter wherein an adjustment to the adjustable-prescription optics overlay by the circuitry depends at least in part on the eye squinting parameter.

16. A system comprising:

a processor;

memory operatively coupled to the processor;

a display operatively coupled to the processor wherein the display emits light rays and wherein the display comprises adjustable optics; and

circuitry that adjusts the adjustable optics based at least in part on a user parameter to alter a focus of light rays emitted by at least a portion of the display.
