What the optics mean.

Erm... that would be the stuff in between you and the sensor. Like the lens. The integrated iSights appear to use plastic fixed-focus lenses, but somehow Apple does an outstanding job with them. I'm guessing they're not focused at infinity like camera phones are, and perhaps that's why? Given that you are sitting in front of the MacBook, etc, it's possible to know roughly where you will be and use a fixed focus....
