This still supports your argument, but the wikipedia entry has a different meaning of the phrase "Apple of my eye".
From the wiki entry[0]: "Its meaning does indeed derive from an expression signifying the pupil of the eye, one of the most sensitive parts of the body. For example, one can tolerate an eyelash on the white of his eye, but let it barely touch the pupil, and everything else is of secondary importance."
It's kind of funny though, I always assumed it was like saying, "out of all the apples around me, you're the one that I notice, the one apple I see with my eye". And all of these definitions kind of hint at the same point. Definitely a misunderstood quote.
