Not your "usual" anatomy book ! 🙂 
Introduction by Bruce Wayne 😐
Superman has multiple lenses not just one for micro and telescopic vison . He can perceive wide range of the EM spectrum including gamma rays and he can use his eyes as weapon to generate heat beam equivalent to energy of lightening ! I which our visual system was that complex 🤔
How is Superman so strong ? His heart has bivalves and trivalves ! His muscle filaments (myofilament) are several times thicker than human and he as “conscious” control over his peripheral blood vessels ! It’s not “autonomic” it’s voluntary blood vessel contractions ! 😄
What about his brain ? He has a larger occipital cortex to support his visual capabilities , his thalamus is significantly larger than humans to process immense amount of sensory data and his synaptic matrices run deep into his frontal lobe to process and analyze data quickly! 🙂
