1. A display system comprising:
a display panel having a pixel array;
a light source that illuminates the pixel array to produce image light that includes an image, wherein the image has a central region of pixels and a peripheral region of pixels surrounding the central region of pixels;
a waveguide; and
a lens configured to receive the image light, wherein the lens is further configured to direct the image light towards the waveguide while applying a first magnification to the pixels in the peripheral region of the image and a second magnification to the pixels in the central region of the image, wherein the first magnification is greater than the second magnification, and wherein the waveguide is configured to propagate the image light as a foveated image via total internal reflection.
