Abstract

In functional terms, the cornea constitutes the foremost interface between the outer world and the cognitive system. Photons, on their way to retinal photoreceptors are here first confronted with a diffractive surface. The consecutive optical media from the cornea inwards are the narrow gateway through which informational bits have to pass before being processed in the neuronal system, starting in the retina itself.
