1. An electronic display assembly comprising:

  • a first microlens layer on a first side of a circuit board and comprising a first plurality of cells, the first plurality of cells being arranged in a grid pattern comprising a center cell and a plurality of surrounding cells that surround the center cell;

    a pixel array layer adjacent to the first microlens layer, the pixel array layer comprising a plurality of display pixels;

    a second microlens layer on an opposite side of the circuit board from the first microlens layer, the second microlens layer comprising a second plurality of cells;

    an image sensor layer adjacent to the second microlens layer, the image sensor layer comprising a plurality of sensor pixels configured to detect incoming light through the second plurality of cells; and

    a logic unit layer coupled to the circuit board, the logic unit layer comprising logic configured to;

    display, using some of the plurality of display pixels, a sub-image in each particular cell of the first plurality of cells;

    access vision correction parameters of a user;

    perform linear transformations on a plurality of the sub-images of the surrounding cells according to the vision correction parameters of the user; and

    shift the plurality of sub-images of the surrounding cells according to the linear transformations, thereby providing digital vision correction for the user;

    wherein each cell of the first and second plurality of cells comprises;

    a transparent lenslet; and

    a plurality of opaque walls configured to prevent light from bleeding into adjacent cells.
