In vertebrate eyes, the nerve fibers route before the retina, blocking some light and creating a blind spot where the fibers pass through the retina. In cephalopod eyes, the nerve fibers route behind the retina, and do not block light or disrupt the retina. 1 is the retina and 2 the nerve fibers. 3 is the optic nerve. 4 is the vertebrate blind ...
Seen from the side, its eyes are rectangular. This cylindrical design, with the lens centered, results in a restricted horizontal field of vision, but is thought to be an adaptation that reduces the eye's silhouette when viewed from below as part of the animal's method of camouflage . [ 5 ]

In extreme cases such eyes may fuse, effectively into a single eye, as in some of the Copepoda, notably in the genus Cyclops.
