1. A display device for displaying an image to a user having a visual impairment, the display device comprising:
a pixelated display comprising a plurality of pixels, each pixel comprising a plurality of subpixels;
an eye-tracking system for tracking a position of an eye of a user relative to the pixelated display;
a microlens array provided on the pixelated display; and
a processor;
wherein the processor is configured to:
determine, based on a focal length of the eye, a location of a virtual image plane, the virtual image plane corresponding to a viewing location of the eye and comprising a plurality of virtual pixels;
relate, for each subpixel, the subpixel to a corresponding virtual pixel of the virtual image plane by determining a path of a light ray emitted by the subpixel to the corresponding virtual pixel,
determine, for each subpixel, a first value of the subpixel by comparing a value of the subpixel to a value of its corresponding virtual pixel,
operate each subpixel based on the determined first value to display a corrected image on the pixelated display.
