1. A system for displaying a virtual image to a user, the system comprising:
a light engine to generate a display light representing the virtual image;
one or more processors communicatively coupled to the light engine to modify the virtual image;
a diffractive waveguide optically coupled to an outcoupler for directing at least a portion of the display light from the diffractive waveguide to an eye of the user;
an incoupler optically coupled to the diffractive waveguide, the incoupler to receive the display light from the light engine and to direct the received display light to the diffractive waveguide; and
wherein the diffractive waveguide is configured to converge a first component light of the generated display light at a first focal distance from the eye of the user, and to converge at least one additional component light of the generated display light at one or more distinct other focal distances from the eye of the user; and
wherein to modify the virtual image includes to modify one or more aspects of the virtual image in order to compensate for a distortion that is based at least in part on convergence of the at least one additional component light at the one or more distinct other focal distances.
