Thy hands have made me and fashioned me:
Psalm 119:73
"There are approximately 120 million rods and 6 million cones in each eye, with the cones being more concentrated toward the rear of the retina. In the retina, the photo-receptor cells synapse (or connect) directly onto receptors, which in turn synapse onto ganglion cells of the outermost layer, which then conduct impulses to the brain.
Lying at the rear of the brain, the visual cortex is the largest system in the human brain and is responsible for processing the visual image. The human mind recognizes objects with highest contrast to their surroundings first." BMD
