Humans would have a triple eyelid too like camels so you could close one to prevent snowblindness, keep out the dust, and walk into windstorms, dust storms, and truck exhaust without having to wear goggles or close your eyes completely. In fact I might give humans another set of eyes either with telescopic vision equal to that of a bird of prey, or extreme night vision (or at least a tapetum for cat night vision), and a mechanism for comfortably keeping them closed when the other eyes were open.
One set of eyes would have to be able to see ultraviolet too, and would be able to directly appreciate a sunset without lasting eye damage. All eyes would recover from damage, and no one would need to wear glasses. Dry eye syndrome and eye diseases would not exist and progress.
I think I would give humans a prehensile long tail too for grasping objects, and maybe a pair of swiveling Andalite antlers with another set of eyes on the tip so you could check your surroundings for predators or enemies without moving your head. This set could move independently of each other like a chameleon's. Either that or dragon fly eyes on the side of your neck for giving you 360 degree vision - nothing could sneak up on you.
Everyone would be born with nanites for self repair (no more cancer), and you would have a super computer stored inside of you for memorizing facts, storing a photographic/sensory memory, doing calculations, and automating daily tasks. This computer would be able to hook up to the internet too via wi-fi or something so you could mentally chat or share memories.
