1. A method for manipulating light using an artificial reality (XR) system to control an image shell at a user's eye, the method comprising:
displaying, by the XR system, an XR environment to a user;
tracking, by the XR system, one or more of the user's eyes, the user eye tracking comprising at least pupil tracking; and
manipulating light entering the user's eye by varying one or more physical characteristics of one or more lenses of the XR system according to the user's tracked eye position, the one or more lenses comprising an optical component of the XR system,
wherein the manipulating controls one or more optical parameters of an image shell created at the user's eye by the entering light,
wherein the controlled one or more optical parameters comprise at least a peripheral curvature of the image shell or a center of curvature of the image shell,
wherein the peripheral curvature of the image shell relates to its curvature relative to a peripheral retina of the user's eye, and
wherein the center of curvature of the image shell corresponds to a point that is a distance from the image shell curvature equal to a radius of the image shell curvature.
