The Optina project uses a hyperspectral retinal camera to detect patterns on a sub molecular level. The following description is offered on their web site.
The eye offers a natural window to the brain via the retina. This light-sensitive layer, which lines the interior of the eye, is an extension of our central nervous system. Recent research has reported that the Aβ photon imprinting plaques in the retinas of both humans and mice continue to receive and store neurological charges for as long as 2 minutes after death. This discovery opens the possibility that these patterns could in fact constitute a 2 minute window into the metaphysical plane.
What we perceive here is largely open to interpretation. In Arbour’s words “The vivacity of thing is not furthered nor hindered by a photograph. Both are simply external visual data. If you do not believe that you will be able to see through the firmament into the metaphysical, you wont be.”
