The Blind Spot Explained

You cannot see everything!
The eyes relay the image that forms on the retina to the brain via the Optic Nerves. These nerves connect to the retina from the inside, a quirk of evolution. Thus there is a blind spot at the back of each of our eyes where no rods or cones can interpret the image formed there.
