1. An eye-mountable device comprising:

  • a transparent material having a central region, a concave surface and a convex surface, wherein the concave surface is configured to be removably mounted on a corneal surface overlaying a pupil and the convex surface is configured to be compatible with eyelid motion when the concave surface is mounted on the corneal surface;

    a ring-shaped substrate at least partially embedded in the transparent material;

    a light source disposed on the ring-shaped substrate away from the central region of the transparent material, wherein the light source is configured to emit light that is viewable through the pupil when the concave surface is mounted on the corneal surface; and

    circuitry disposed on the ring-shaped substrate, wherein the circuitry is configured to modulate the light emitted by the light source to provide modulated light.
