Devices and methods for a contact lens with an inward facing light source

摘要

An eye-mountable device can include a transparent material and a substrate at least partially embedded in the transparent material. The transparent material can have a concave surface and a convex surface, with the concave surface configured to removably mount the eye-mountable device on a corneal surface overlaying a pupil. A light source can be disposed on the substrate and configured to emit light through the concave surface and towards the corneal surface such that the emitted light is viewable through the pupil. The light source can be controlled by circuitry disposed on the substrate. The circuitry can be configured to modulate the light emitted by the light source to provide modulated light.

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.
