1. An augmented reality device comprising:
a frame having a user-facing side and real-world facing side and comprising an aperture;
a light projector configured to emit light;
an optical combiner configured to receive the light and output a virtual image within a user field of view, wherein the virtual image is visible through a portion of the aperture;
a first optical lens attached to the frame at the real-world facing side, wherein the first optical lens is disposed in only the portion of the aperture, and wherein the entirety of the first optical lens is characterized by a first optical power that provides a near-field correction; and
a second optical lens attached to the frame at the user-facing side, wherein the second optical lens is disposed in and fully occupies the aperture, and wherein the entirety of the second optical lens is characterized by a second optical power that provides a far-field correction;
wherein the optical combiner is disposed in the aperture and between the first optical lens and the second optical lens, and
wherein the first optical power has a first value that equals a value of the near-field correction minus a second value of the second optical power.
