  Curb feelers? Nah, I am going to go with Optically tested and Corrected vision. A uniquely human trait.

    That's what's usually called a Mk1 eyeball, but the OP said the Mk2 eyeball so I'm curious what he considers the predecessor.

  Urban Dictionary comes to the rescue: "Mk1 Eyeballs: Unaided vision. Commonly used by military internet know it alls to confuse people in an argument." I don't know whether MkII is an upgrade to aided vision or just a new version of the confusion. http://www.urbandictionary.com/define.php?term=Mk1%20eyeball http://www.urbandictionary.com/define.php?term=Mk1%20eyeball
