convergently evolved eyes, cephalod pod eyes evolved very differently from tetrapods. cephalpod eyes evolved by forming an invagination of those tissues. whereas the tetrapods evolved as extensions of thier brain.

plus cephalopods eyes are more like a camera, the lens move back and forth, instead of changing shapes. they do have exceptions which allows them to simulate eyes of tetrapods. they also possess the ability to regenerate thier eyes too.
