This paper relates to the marked differences between the eyes of invertebrates and vertebrates with particular reference to retinal function and structure, the latter accentuating grave problems in their supposed evolutionary development. In image-producing eyes (Cephalopods and vertebrates) the exceedingly unlikely occurrence of two distinct and structurally contrasting retinas evolving by any non-teleological chance process is discussed. From the material presented it is concluded that omniscient Intelligence has designed and created the organs of vision as we encounter them in living organisms.
