1. An eye-mounted display comprising:

  • a contact lens containing a plurality of femtoprojectors that project an image to a user'"'"'s retina;

    the plurality of femtoprojectors including a first group of one or more central femtoprojectors that projects a first portion of the image with a first resolution to a first region of the retina, where each central femtoprojector comprises reflective optics;

    the plurality of femtoprojectors further including a second group of one or more peripheral femtoprojectors that projects a second portion of the image with a second resolution to a more peripheral region of the retina, where the second resolution is lower than the first resolution;

    each of the peripheral femtoprojectors comprising;

    an image source;

    an optically transparent core bounded by a first end and a second end opposite the first end;

    a sidewall structure that extends between the two ends; and

    a lens element positioned at the second end.
