Both these photoreceptors A camera and the human eye have much in common, far more than just the ability to capture images. Unlike the vertebrate eye, a cephalopod eye is focused through movement, much like the lens of a camera or telescope, rather than changing shape as the lens in the human eye does. But animals that live in water, which has a high refractive index compared with air, need stronger lenses. Lv 4.

The human eye is often compared with a camera. Eyes and wings are among the most stunning innovations evolution has created. The structure of human and octopus eye is shown in figure 2. Structurally, that is the only difference between the eyes. This is the point at which the octopus eye and the human eye began to diverge and evolve independently to the eyes we and the octopi have today. This gives us binocular vision, so except for the images on the periphery of our vision, we use both eyes to see clearly.

But then — without any possible cross-communication — another Pax6 gene on a completely separate branch leading to vertebrates had to learn to create a camera eye … This gives us the ability to see how far an object is (a phenomenon known as depth of field) and how quickly something is moving (a speeding car, for example). Why would animals so distantly related as a fish and a cephalopod have developed an eye that is so similar? However, the octopus and the human are not closely related and reside far from each other on the phylogenetic tree of life.

Its rods and cones face forwards, and blood supply and nerves come from behind. These … However, the optic ganglion of an octopus is behind the retina already and so there is not a blind spot present in there vision.
