1. A system comprising:
a head-mounted support structure;
a display coupled to the head-mounted support structure that is configured to provide an image containing computer-generated content; and
an optical system that has a first lens, a second lens, and an optical coupler and that provides the image using the optical coupler to an eye box through the first lens while a real-world object is visible through the first and second lenses from the eye box, wherein the first lens has a vision-correction component and a projection bias component, and wherein the second lens has a compensation bias component that compensates for the projection bias component.
