nanoflowers seeded from nano-sized particles of metals that grow, or self assemble, in a natural process. Eye surgeons would implant these fractal devices within the eyes of blind patients, providing interface circuitry that would collect light captured by the retina and guide it with almost 100 percent efficiency to neurons for relay to the optic nerve to process vision.

A section through the choroid layer of the eye. A pigment cell (red) is at upper center. The choroid layer lies behind the sclera (white of the eye) and in front of the retina. It is highly vascular and supplies blood to the back of the eye. It is pigmented to absorb excessive light, preventing internal reflections that would form multiple images on the retina.
In the scanning electron micrograph above, from Joseph Lust at the University of Rochester, part of the inner eye is revealed densely packed ganglion cells (false-colored green) are neurons that take visual information collected by the retina and transmit it to the brain. Photoreceptor rod cells, primarily used in night vision, are colored blue. Retinal pigmented epithelium is colored orange. This single layer of pigmented cells shields the retina from excessive incoming light.
