Here you can see where the ASR is placed between the outer and inner retinal layers. Photo courtesy Optobionics The ASR contains about 3,500 microscopicsolar cellsthat are able to convertlightintoelectricalpulses, mimicking the function of cones and rods. To implant this device into the eye, ...
Through the cornea, the light is refracted and continues into the eye through the lens to then reach the retina. The image is filtered and processed as soon as it reaches the retina, and then sent to the brain's vision center for a complete interpretation. The eye can be compared to a...
