1. An apparatus, comprising:
a first lens located a first distance from an eye of a user, the first lens being adapted to:
receive, at a first optical region 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;
a see-through display located a second distance from the eye, the see-through display being is adapted to:
receive the environment content from the first lens; and
deliver the environment content and display content to a second lens; and
the second lens located a third distance from the eye, the second lens being is adapted to:
receive, at a first optical region 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.
