1. An apparatus, comprising:

a first lens located a first distance from an eye of a user, the first lens comprising a first array of optical elements, wherein the first lens is adapted to:

receive, at a first optic of the first lens, environment content from a location in front of the first lens relative to the eye; and

alter a focal vergence of the environment content;

receive the environment content from the first optic of the first lens; and

deliver the environment content and display content to a second lens, the second lens comprising a second array of optical elements; and

wherein the second lens is located a third distance from the eye, and wherein the second lens is adapted to:

receive, at a first optic of the second lens, the environment content and the display content from the see-through display;

alter the focal vergence of the environment content; and

alter a focal vergence of the display content, wherein the focal vergence of the display content is alterable substantially independent of the focal vergence of the environment content.

2. The apparatus of claim 1 , further comprising an environment sensor adapted to sense a distance along a target path from the apparatus to the location in front of the first lens.

3. The apparatus of claim 1 , wherein the first lens is adapted to alter the focal vergence of the environment content in the first optic of the first lens substantially independent of altering the environment content at a second optic of the first lens.

4. The apparatus of claim 1 , wherein the first lens is adapted to alter the focal vergence of the environment content in the first optic of the first lens substantially concurrent to altering the environment content at a second optic of the first lens.

5. The apparatus of claim 1 , wherein the second lens is adapted to alter the focal vergence of the environment content in the first optic of the second lens substantially independent of altering the environment content at a second optic of the second lens.

6. The apparatus of claim 1 , wherein the second lens is adapted to alter the focal vergence of the environment content in the first optic of the second lens substantially concurrent to altering the environment content at a second optic of the second lens.

7. The apparatus of claim 1 , comprising a receiver sensor adapted to sense an orientation of a sight path of the eye, wherein:

the first lens is adapted to alter the focal vergence of the environment content substantially exclusively in the first optic of the first lens along the sight path; and

the second lens is adapted to alter the focal vergence of the environment content and the focal vergence of the display content substantially exclusively in the first optic of the second lens along the sight path.

8. The apparatus of claim 1 , comprising a receiver sensor adapted to sense an orientation of a sight path of the eye, wherein:

the first lens is adapted to alter the focal vergence of the environment content substantially concurrently in the first optic of the first lens along the sight path and a second optic of the first lens along the sight path; and

the second lens is adapted to alter the focal vergence of the environment content and the focal vergence of the display content substantially concurrently in the first optic of the second lens along the sight path and a second optic of the second lens along the sight path.

9. The apparatus of claim 1 , wherein the environment content after alteration by the first lens and second lens is substantially equal to the focal vergence of the environment content before alteration by either the first lens or the second lens.

10. The apparatus of claim 1 , wherein the first lens is adapted to alter the focal vergence of the environment content in the first optic of the first lens along an interaction path from the eye to an interaction entity external to the apparatus.

11. The apparatus of claim 1 , wherein the second lens is adapted to alter the focal vergence of the environment content in the first optic of the second lens along an interaction path from the eye to an interaction entity external to the apparatus.

12. The apparatus of claim 1 , comprising a see-through modifier comprising a modifier region adapted to:

receive environment content at the modifier region; and

apply a modification to an optical property of the environment content in the modifier region.

13. The apparatus of claim 12 , wherein the modification comprises at least one of a darkening the environment content, changing in opacity level of the environment content, lightening environment content, or changing a color of the environment content.

14. The apparatus of claim 1 , wherein:

the first distance is longer than the second distance or the third distance; and

the second distance is longer than the third distance.

15. A device, comprising:

a first lens located a first distance from an optical receiver, the first lens comprising a first array of optical elements, wherein the first lens is adapted to:

receive environment content from a location in front of the first lens relative to the optical receiver; and

alter a focal vergence of the environment content;

a see-through display located a second distance from the optical receiver, wherein the see-through display is adapted to:

receive the environment content from the first lens; and

deliver the environment content and display content to a second lens, the second lens comprising a second array of optical elements; and

the second lens located a third distance from the optical receiver, wherein the second lens is adapted to:

receive the environment content and the display content from the see-through display;

alter the focal vergence of the environment content; and

alter a focal vergence of the display content.

16. The device of claim 15 , wherein the focal vergence of the display content is alterable substantially independent of the focal vergence of the environment content.

17. The device of claim 15 , wherein the optical receiver is an eye of a user or a camera.
